Species of Deiracephalus Resser, 1935, are rare elements in most Guzhangian (upper Marjuman) trilobite faunas of Laurentian North America, and are characterized by striking cephalic spinosity that includes very long genal and occipital or preoccipital glabellar spines. Almost all previous reports of the genus have assigned sclerites to two species, Deiracephalus aster (Walcott, 1916) and Deiracephalus unicornis Palmer, 1962. However, new material from the Shallow Bay Formation of western Newfoundland and restudy of type material from the southern Appalachians show that as many as eight species are present, although not all of them are sufficiently well known to be formally named. Deiracephalus aster and D. unicornis are restricted to their respective holotypes from the Conasauga Formation of Alabama; new species from the Shallow Bay Formation are Deiracephalus narwhali, Deiracephalus rhinocerotis, Deiracephalus dynastoides, and Deiracephalus phanaeus. Deiracephalus unicornis, D. narwhali, D. rhinocerotis, and a poorly known species from Nevada all possess preoccipital glabellar spines, and form an informal “unicornis group” of species. This group occurs high in the traditional Crepicephalus Zone (latest Guzhangian) and offers a potentially important means of biostratigraphic correlation. Species with occipital spines are older than the unicornis group and extend down into the Cedaria Zone as used traditionally in North America.

Sixty-two taxa are recognized in this study of the species of Puccinia completing their life cycle on Heliantheae. Six new species are described: Puccinia guatemalensis Parmelee on Zexmenia spp. and Wedelia spp., P. ghiesbreghtii Parmelee on Wedelia ghiesbreghtii, P. abramsii Parmelee on Geraea viscida (= Encelia viscida), P. chloracae Parmelee on Viguiera spp., P. calanticariae Parmelee on Viguiera spp., and P. praetermissa Parmelee on Lagascea spp. Six new varieties are recognized: Puccinia electrae var. robusta Parmelee and P. electrae var. depressiporosa Parmelee on Zexmenia brevifolia, P. caleae var. cuernavacae Parmelee on Calea spp., P. cognata var. echinulata Parmelee on Verbesina spp., P. cognata var. fraseri Parmelee on Viguiera fraseri, and P. affinis var. triporosa Parmelee on Viguiera spp. Three taxa have been restored from synonomy under P. abrupta, viz. P. subglobosa, P. ximenesiae, and P. affinis, the last two parasitic on Verbesina spp., the first on Rhysolepis (= Viguiera). P. tithoniae, P. nanomitra, and P. ordinata, are reduced to synonomy with P. enceliae var. enceliae, P. iostephanes, and P. melampodii respectively. New combinations include: P. enceliae var. aemulans (Syd.) Parmelee and P. abrupta var. partheniicola (Jacks.) Parmelee. A key based on uredinial and telial characters, others based initially on the hosts, and a host index are provided. Each taxon is illustrated by a photomicrograph from type material. Distribution and host extensions, supplementary to those given in Arthur's Manual of the Rusts, are indicated.

Echinus gyracanthus Eaton, 1832, was the first tentaculitid reported from North America, but the original description and illustration are vague by present-day standards. Study of the type material and topotypes from the Lower Devonian Manlius Limestone in the Town of Schoharie, New York, suggests that Tentaculites gyracanthus (Eaton) is a discrete species, but one with pronounced and remarkable intraspecific variability. Tentaculites simmondsi new species also occurs in the same unit and locality.

Distinct Taxon

Exceptionally well preserved Lower Triassic conodonts from Oman include an array ofNeospathodusspecies, many of which are new. Those from the upper Lower Triassic, or Spathian, are described in conjunction with a restudy of conodont type material from Chios, Greece, and an assessment of contemporary collections from Pakistan and western North America. The taxonomic scope of three key species from Chios,Neospathodus homeri, N. triangularis, andN. gondolelloides, is revised. Seven new species are described from Oman:N. abruptus, N. brevissimus, N. brochus, N. crassatus, N. curtatus, N. pusillus, andN. symmetricus;and one new species,N. clinatus, is described from Pakistan. The alliedIcriospathodus collinsoniis also described from Oman. The occurrence and range ofNeospathodusspecies are presented in the context of the ammonoid succession in the Spathian of North America. BothN. homeriandN. triangularis, as revised, have shorter ranges and are more age diagnostic than previously thought.Neospathodus gondolelloidesis a distinct taxon, and not synonymous withChiosella timorensis.Five informal faunal divisions are identified based onNeospathodusand allied species. In ascending stratigraphic order, these are typified byIcriospathodus collinsoni, Neospathodus homeri, N. triangularis, N. symmetricus, andN. gondolelloides.Oman collections represent three of these faunas, which occur also in theColumbitesthroughProhungarites/Subcolumbitesammonoid beds of western U.S.A.

Established Species

Almost all of the members of the subfamily Ethopolyinae occur in western North America, a few Pacific islands, the Orient and Europe, but only one established species had been known from North America east of the Rocky Mountains. This widespread and very common form, Bothropolys multidentatus (Newport), ranges throughout the East as far west as Missouri. The present new species is therefore of special interest in that it is the second endemic member of the subfamily to he recorded from east of the Rockies. The only other members of Zygethopolys, a genus closely allied to Bothropolys, are known only from Alaska, British Columbia, and thk state of Washington.

The Neotropical species of Genea Rondani, 1850 (Diptera, Tachinidae, Tachininae, Leskiini) are revised by the examination of type-material of almost all species and a large material deposited in many scientific collections. G. australis (Townsend), G. brasiliensis (Townsend), G. gracilis James, G. jaynesi (Aldrich), G. major (Townsend), G. pellucens (Curran), G. tenuirostris (James), G. trifaria (Wiedemann) were keyed and redescribed with the first descriptions of male terminalia. G. longipalpis (Wulp) was not included in this study as no material was examined and the available data are restricted to the original description. G. glossata (Townsend) is proposed as a junior synonym of G. trifaria. G. paulistana sp. nov. from São Paulo is proposed as a new species.

The key presents all 59 species of the genus Trichocera Meigen which occur in Europe. Four subgenera are represented: Trichocera Meigen 1803 (five species), Metatrichocera Dahl 1967 (seven species), Saltrichocera Krzemińska 2002 (35 species), and Staryia Krzemińska & Gorzka 2016 (13 species). The type material of two species, one from North America and one from Asia, are described (Trichocera columbiana Alexander, 1927 and T. arctica Lundström, 1915), whose identities cause some problems and whose presence in the northern regions of Europe is possible. Two new species are described, Trichocera (Saltrichocera) longa, n. sp., and T. (Staryia) oulankae, n. sp. Trichocera versicolor is resurrected from synonymy; T. limpidipennis is synonymized with T. regelationis. There are separate keys to males and females; species are illustrated with camera pictures of diagnostic features: genitalia, antennae, and male tarsal claws, and additionally, wings and thoraces when only one sex is known, to enable further search. The state of knowledge of the genus in Europe and in the world is discussed.

Ceratophyllus Gallinae

One may well assume that almost all the Nearctic species of mammalian fleas have probably been discovered. Concentrated collecting and study of mammals and their parasites for more than half a century has not only yielded a largely complete roster of the flea species present but has also elucidated the geographical distributions and host associations of many of them. However, this can hardly be said for the bird flea, which have been relatively neglected. The distributions and ecology of the known species are imperfectly understood and interesting records and new species can still be found, especially in the western and northern parts of the region, if one takes the trouble to search. For example, recent collections from birds' nests in Alaska, made by Dr. Robert Rausch, have yielded a number of distributional surprises (e.g., Ceratophyllus gallinae (Schrank), formerly believed to be confined to eastern North America) and examination of the nests of a mere six species of birds by the writer and J. E. H. Martin of the Entomology Research Institute during a brief collecting trip on the Alaska Highway in August, 1959, revealed five species of fleas, all belonging to the genus Ceratophyllus Curtis, and including two of special interest. One of these is new to science. The second, identified here as Ceratophyllus balati Rosicky, a species recorded in the literature only from Czechoslovakia, is redescribed here for the convenience of North American students, and also to supplement the original description. In addition to describing these, the writer wishes, in this paper, to emphasize the paucity of our knowledge of bird fleas in the hope that ornithologists and others who may find opportunities to collect and examine birds' nests (after the fledglings have left) will search for fleas.
