This work was inspired by conversations with a community of practice based at Nunavut Arctic College in Iqaluit, including Andrea Burry, Maryse Cohen, Goota Jaw, Kaviq Kaluraq, and Gloria Uluqsi. The author gratefully acknowledges their contributions, as well as theindispensable contribution of the land itself.We outline the broad epistemic tendencies of Inuit and Qallunaaq[i] teaching, in the context of a faculty member in the Mathematics department of a large, research-oriented Qallunaaq university. We argue that, against the recommendations of academic literature, historical support and personal experience, the South maintains a position of strong cultural assertiveness. Finally, we propose two shifts in position, aimed at protecting the North and learning from it, that centre the Inuit voice.[i] While Qallunaaq simply means “non-Inuit” (the noun is Qallunaat), the implied meaning here, as in common usage, is “settler Canadian” or “settler North American”.

A Small collection of fossils from the Bokkeveld Beds has recently been sent to me for identification by the South African Museum, and some of them have been generously presented to the Sedgwick Museum. Amongst this material it is interesting to find some genera not previously recorded from the Cape and some new species. The majority of the specimens are in the condition of internal casts, and hence present especial difficulties in their determination, so that in a few cases some uncertainty must remain as to the generic position of the fossils. However, I am able to record for the first time from these beds the occurrence of the well-known lamellibranchiate genus Buchiola, and of a shell which may be identified with Nyussa arguta, Hall, of the North American Devonian. The genus Buchiola occurs in argillaceous nodules from the Zwartberg Pass crowded with individuals of the species which I have named B. subpalmata and with a few examples of an undetermined species. No other associated fossils can be recognised in these nodules, but I am informed that an abundant fauna is found in the beds at this locality.

Again, the genera Citheronia and Eacles are a South American element in our fauna, while the typical Attacinæ, such as Actias, probably belong to the Old World element in our fauna, together with all our Platypteryginœ. Among the Hawk Moths the genera Philampelus and Phlegethontius are of probable South American extraction, though represented now by certain strictly North American species. Mr. Robert Bunker, writing from Rochester, N. Y., records the fact that Philampelus Pandorus, going into chrysaiis Augnst 1, came out Sept. 10 as a moth, showing that in a warmer climate the species would become doublebrooded. And this is undoubtedly the case with many species the farther we go South, where insect activities are not interrupted so long and so strictly by the cold of winter. Since the continuance of the pupal condition is influenced by cold, a diminishing seasonal temperature for ages may have originally affected, if not induced, the transformations of insects as a whole. Butterflies and Moths which are single brooded in the North become double brooded in the South.

We describe a new species of chorus frog of the North American treefrog genus Pseudacris from the south-central United States. This new species is morphologically similar to the parapatric species P. feriarum and has thus previously been considered synonymous with this species. The new species is geographically distinct from P. feriarum and from its sister species, P. nigrita. We diagnose the new species based on advertisement call, morphological, and genetic characters.

The Nahanni and Liard mountain ranges are located at about 61° N latitude and 122° W longitude. They form the easternmost slopes of the Rocky Mountains and lie just east of Nahanni National Park in the southwestern corner of the District of Mackenzie, Northwest Territories. The moss flora of the area is rich in the number of taxa; 207 species and two varieties are reported from this relatively small area. Of these, 53 species are new records for the South Nahanni region. A number of rare or disjunct bryophyte species are found in the area. Moss species which are either disjunct or occur at the edge of their range include Arctoa fulvella (Dicks.) B.S.G., Aulacomnium acuminatum (Lindb. & Arn.) Kindb., Andreaeobryum macrosporum Steere & B. Murray, Geheebia gigantea (Funck) Boul., Isopterygiopsis muelleriana (Schimp.) Iwats., Mnium spinosum (Voit) Schwaegr., Psilopilum cavifolium (Wils.) Hagen, Rhabdoweisia crispata (With.) Lindb., Seligeria calcarea (Hedw.) B.S.G., S. polaris Berggr., Trematodon brevicollis Hornsch., and Trichostomum arcticum Kaal. The North American distribution of these species is mapped. Herbertus stramineus (Dum.) Trev., Metacalypogeia schusterana Hatt. & Mizut., Scapania crassiretis Bryhn, and S. simmonsii Bryhn & Kaal. are four hepatic species of phytogeographic interest.

When the isthmian land bridge triggered the Great American Interchange, a large majority of land-mammal families crossed reciprocally between North and South America at about 2.5 Ma (i.e., Late Pliocene). Initially land-mammal dynamics proceeded as predicted by equilibrium theory, with roughly equal reciprocal mingling on both continents. Also as predicted, the impact of the interchange faded in North America after about 1 m.y. In South America, contrary to such predictions, the interchange became decidedly unbalanced: during the Pleistocene, groups of North American origin continued to diversify at exponential rates. Whereas only about 10% of North American genera are derived from southern immigrants, more than half of the modern mammalian fauna of South America, measured at the generic level, stems from northern immigrants. In addition, extinctions more severely decimated interchange taxa in North America, where six families were lost, than in South America, where only two immigrant families became extinct.This paper presents a two-phase ecogeographic model to explain the asymmetrical results of the land-mammal interchange. During the humid interglacial phase, the tropics were dominated by rain forests, and the principal biotic movement was from Amazonia to Central America and southern Mexico. During the more arid glacial phase, savanna habitats extended broadly right through tropical latitudes. Because the source area in the temperate north was six times as large as that in the south, immigrants from the north outnumbered those from the south. One prediction of this hypothesis is that immigrants from the north generally should reach higher latitudes in South America than the opposing contingent of land-mammal taxa in North America. Another prediction is that successful interchange families from the north should experience much of their phylogenetic diversification in low latitudes of North America before the interchange. Insofar as these predictions can be tested, they appear to be upheld.

The interesting new species of water-bug described below was received some time ago from Abbé P. A. Bégin, of Sherbrooke, Canada. It was captured swimming on a fresh-water stream some little distance above Sherbrooke, and is of more than ordinary interest, from the fact that it belongs to the genus Halobatopsis, Bianchi, a genus not yet recognized in the North American fauna, and only recently characterized, being based upon the South American Halobates platensis, Berg., also a fresh-water species.

The act of decentring established Euro-North American sites and flows of knowledge as longstanding geopolitical anchors of epistemological authority presents déjà vu scenarios, involved in centre-staging processes. The very position of being a messenger from the ‘North’ of knowledge and theory from the ‘South’ can reproduce the same patterns the undertaking seeks to unsettle. The context in which academic performativity is shaped is integral to both the making and taking of space in intellectual circuits of production and circulation. This article considers how centre-staging in academia performatively involves particular features. As a case in point, the focus is on the centre-staging of Boaventura de Sousa Santos (epistemology of the South) and Raewyn Connell (Southern Theory), who have become globally known for insisting on bringing knowledge from the South to the North. The wider ecology of the global circuits of academia, as well as their own performative dramaturgy, constitutes points of observation. A self-enterprising ownership of big global conceptual programmes places them high in the decentring of knowledge. There is a leap frogging over former stocks of published academic knowledge, as well as a centre-staging of knowledge projects, whereby it is they who become the flag bearers of this enterprise. Within this process it is important to recognise who is illuminated. Bibliographic tracks become traced over, in the very ways in which fields are mapped in order to produce a point of intervention.

The Lower Pennsylvanian Hale Formation, which comprises the lower portion of the type Morrowan Series, in northwestern Arkansas, is subdivided into the Cane Hill and overlying Prairie Grove Members. The Cane Hill Member includes interbedded shale and sandstone with a basal conglomerate containing clasts reworked from underlying, truncated Mississippian formations. The Prairie Grove Member is highly variable, but includes sandy biosparite and calcareous sandstone. Highly fossiliferous pebble conglomerate and calcirudite lenses occur sporadically throughout the Hale Formation. Ammonoids and conodonts show that the Cane Hill-Prairie Grove boundary is unconformable.Several thousand ammonoids collected from more than 100 localities in the Hale Formation show that four ammonoid zones and two subzones are recognizable in the Hale succession, and consequently in the redefined Halian Stage of the Morrowan Series. These are, in ascending order, the Retites semiretia, Quinnites henbesti, Arkanites relictus (including the Arkanites relictus relictus and overlying Cancelloceras huntsvillense Subzones) and Verneuilites pygmaeus Zones. Halian Stage ammonoids are known primarily from northern Arkansas, but an upper Arkanites relictus Zone (Cancelloceras huntsvillense Subzone) ammonoid assemblage occurs in the Primrose Member of the Golf Course Formation in south central Oklahoma.Conodont-ammonoid associations in the Hale sequence provide a basis for integration of independently based zonal information. Rhachistognathus primus Zone conodonts occur in the Retites semiretia Zone; the Idiognathoides sinuatus Zone ranges through the Quinnites henbesti and Arkanites relictus relictus Subzone. The overlying Cancelloceras huntsvillense Subzone and Verneuilites pygmaeus Zone both contain conodonts of the Neognathodus symmetricus Zone.The Hale ammonoid succession has few, if any, species in common with the type Namurian of Europe, but numerous genera are common to both sequences and the generic successions coincide and are equivalent in degree of development. The Retites semiretia Zone is equivalent to the Reticuloceras circumplicatile Zone (R1a); the Quinnites henbesti and lower Arkanites relictus Zones correspond to some portion of the R2b–R2c interval; and the upper Arkanites relictus Zone and the Verneuilites pygmaeus Zone correlate to Zone G1. The Retites semiretia Zone correlates to the lower Reticuloceras-Baschkortoceras Genozone (Nm2b1) of the upper Namurian in the south Urals; the Quinnites henbesti Zone is equivalent to some portion of the Nm2b2–3 intervals of this zone; the lower Arkanites relictus Zone is equivalent to the lower Bilinguites-Cancelloceras Genozone (Nm2c1) and the upper Arkanites relictus and Verneuilites pygmaeus Zones correspond to the uppermost interval (Nm2c2) in the south Urals sequence.Systematic descriptions of biostratigraphically significant Halian taxa, including Reticuloceras tiro Gordon, R. wainwrighti Quinn, Retites semiretia McCaleb, Arkanites relictus relictus (Quinn, McCaleb, and Webb), A. relictus redivivus n.subsp., Quinnites n.gen. (type species Q. henbesti (Gordon)), Q. textum (Gordon), Bilinguites eliasi n.sp., Cancelloceras huntsvillense n.sp., and Verneuilites pygmaeus (Mather) are also presented.

Europe’s dependency on North American cotton gave the South leverage. Once hostilities began, the Confederates hoped to inspire a diplomatic choice in their favour through economic pressure since France and Britain felt the effects of the “cotton famine.” The Tuileries cabinet tried to determine the origin of the shortage while assessing the real impact of the crisis on the workforce. Though it initially seemed that the North’s blockade of Southern ports was to blame, proof was uncovered that the cotton supply was being intentionally limited with the Southern leaders’ assent, with some Southern planters burning their cotton rather than see it fall into the hands of Northerners. The effects of the cotton crisis were less dramatic than first expected due to the existence of a cotton surplus in France right before the war, alternate suppliers outside Dixie, and the relatively low number of French workers who were directly dependent on cotton. France also did not lose sight of trade in wheat and other products with the states loyal to the Federal government. This concern for trade in the North explains why France, like the United Kingdom, confounded Southern expectations by not recognizing the Confederacy or otherwise intervening in the conflict.

Dyar (1913) listed Diathrausta reconditalis (Walker) as a “form” of the South American D. nerinalis (Walker) and described as new the “form” harlequinalis from Arizona. From the context it is evident that in that paper Dyar used “form” as equivalent to geographic race, and the form names he proposed there can accordingly be treated as valid trinomina. Haimbach (1915), apparently in ignorance of Dyar's paper, described Diathrausta montana from Colorado. This was sunk by Barnes and McDunnough (1917) as a synonym of harlequinalis. Barnes and McDunnough listed harlequinalis as a geographical race of reconditalis, but did not follow Dyar in uniting these with nerinalis.
