The literature on the two described species of Nymphomyiidae, Nymphomyia alba Tokunaga and Palaeodipteron walkeri Ide, is reviewed. Previous opinions on the systematic position of the family and what is known or surmised about their biology are outlined. The occurrence of P. walkeri in Canada is discussed and new records are given from a small upland stream in western Quebec. The larvae of Nymphomyiidae were previously unknown, but those of P. walkeri have been discovered. It is confirmed that they are aquatic. Details of habitat of P. walkeri are given, and the larva is described and figured in detail. An outline of the probable bivoltine life history of this species and some further considerations regarding the relationships of the Nymphomyiidae are also made. An appendix makes additional comments on P. walkeri adults and the opportunity is taken by the second author to describe a new genus and species, Felicitomyia brundini, from the eastern Himalaya.

A new genus and species of amynodontid rhinoceros, Rostriamynodon grangeri, from the early Late Eocene of Inner Mongolia, People's Republic of China, is the most primitive amynodontid recognized to date. Rostriamynodon exhibits the major diagnostic characteristics of amynodontids: quadratic M3, preorbital fossa, and loss of upper and lower P1. It differs from more advanced members of the family in its long preorbital region and lower cheek tooth morphology. Comparisons with other Eocene ceratomorphs show the crucial position Rostriamynodon has in determining phylogenetic relationships between rhinocerotoids and tapiroids. Evidence is presented for the monophyly of the Rhinocerotoidea, including amynodontids.

The new genus Iberostomata (Bryozoa, Ptilodictyina) from the Cystoid Limestone Formation in the Iberian Chains (NE Spain) is here described and its phylogenetic relationships analyzed using cladistic methods. Twenty-eight identifying characters used in traditional systematics have been codified for nine ptilodictyine families, two timanodictyine families and 34 ptilodictyine genera. The results obtained in this analysis place the new genus Iberostomata and the genus Stellatodictya, traditionally included in the family Ptilodictyidae, in the family Rhinidictyidae, question the validity of the family Intraporidae, question the assignment of Amurodictya and Astrovidictya to the family Stictoporellidae, as well as the assignment of the genera Junggarotrypa, Goniotrypa, and Prophyllodictya to the family Rhinidictyidae, and place the family Phragmopheridae in a uncertain systematic position.

Thirty-six species of various thecate hydroids occur in two recent, deep-water collections from off New Caledonia. Of these, nine are new, namely Solenoscyphus subtilis Galea, sp. nov., Hincksella immersa Galea, sp. nov., Synthecium rectangulatum Galea, sp. nov., Diphasia alternata Galea, sp. nov., Dynamena opposita Galea, sp. nov., Hydrallmania clavaformis Galea, sp. nov., Symplectoscyphus acutustriatus Galea, sp. nov., Symplectoscyphus elongatulus Galea, sp. nov. and Zygophylax niger Galea, sp. nov. The male and female gonothecae of Caledoniana decussata Galea, 2015, the female gonothecae of Caledoniana microgona Galea, 2015, as well as the gonothecae of both sexes of Solenoscyphus striatus Galea, 2015 are described for the first time. The systematic position of the genera Solenoscyphus Galea, 2015 and Caledoniana Galea, 2015 is discussed on both morphological and molecular grounds, and both are confidently placed within the family Staurothecidae Maronna et al., 2016. In light of the molecular data, the genera Billardia Totton, 1930 and Dictyocladium Allman, 1888 are assigned to the families Syntheciidae Marktanner-Turneretscher, 1890 and Symplectoscyphidae Maronna et al. , 2016, respectively. The previously undescribed gonothecae of Hincksella neocaledonica Galea, 2015, and the male gonothecae of Sertularella tronconica Galea, 2016, were found. Thyroscyphus scorpioides Vervoort, 1993, a peculiar hydroid with putative stem nematothecae, is redescribed and assigned to the new genus Tuberocaulus Galea, gen. nov. Noteworthy new records from the study area are: Tasmanaria edentula (Bale, 1924), Hincksella sibogae Billard, 1918, Dictyocladium reticulatum (Kirchenpauer, 1884), Salacia sinuosa (Bale, 1888) and Billardia hyalina Vervoort & Watson, 2003. Most species are illustrated to facilitate their identification, and the morphology of the new ones is compared to that of their related congeners.

Decaying Wood

1. An account is given of Aproctonema entomophagum Keilin 1917, a Nematode parasite of the larvae of a Mycetophilid fly, Sciara pullula Winn., inhabiting decaying wood.2. The life history of this parasite is remarkable in the following respects:(a) The free-living stage is very short.(b) Both sexes are parasitic.(c) The usual host is the larva of the fly, from which the parasite escapes by actively breaking through the skin; but some parasites may be carried through to the imagines, from which they escape largely by the aid of the egg-laying movements provoked by them in the flies.3. Metamorphosis of the Sciara larva is delayed by the parasitism, so that at least two generations of Nematodes may be found in one host.4. All the parasitised imagines so far examined have been females.5. The systematic position of Aproctonema is discussed, the conclusion being that this worm and its near relative, Tetradonema plicans Cobb 1919, represent two closely allied genera of the family Mermithidae, but are not synonymous with Mermis. It is proposed to dispense with the family Tetra-donematidae Cobb.

A Preliminary outline of the life history of the lungworm of the cat and its confusion with that of Ollulanus tricuspis, has been given in a previous paper. Since that paper was published, the name of the family of lungworms has been changed to Protostrongylidæ by Professor Leiper; and an examination of adults of the lungworm from the cat, shewed that it belonged to a different genus from the type of the old genus Synthetocaulus. To this new genus, the name ælurostrongylus has been given.

AbstractMicroberotha macculloughigen. nov. and sp. nov. from Early Eocene Okanagan Highlands amber of Hat Creek, British Columbia, Canada, is described. This new genus and species represents one of the smallest members of the family Berothidae and the first occurrence of the family in the New World Tertiary. The systematic position of the genus Microberotha within the family is rather unclear, but the structure of the male genitalia indicates a close association with the subfamily Cyrenoberothinae. Stratigraphy and palaeoenvironment of the Hat Creek locality are briefly discussed.

The bogidiellid amphipod crustaceans Stockigi diella aequim ana new genus and species and Om angidiella p arvid actyl a new genus and species are described from subterranean groundwater habitats in the Sultanate of Oman on the Arabian Peninsula. Stockigidiell a is easily distinguished by a row of long, deeply bifid setae on pereopods 5 and 6, whereas Omangidiell a is distinguished by a greatly reduced propodus of gnathopod 2 and elongate oostegites; it also possesses a third coxal lobe on the maxilliped, a unique character noted only in three other bogidiellid genera from northern and eastern Africa. At present, the family Bogidiellidae contains 35 genera and 105 species but a significant number of provisionally recognized new species and possibly several new genera await description. The geographic distribution of the family Bogidiellidae is nearly circumglobal, but species tend to be clustered in discontinuous regions. A number of important questions regarding the origin and biogeographic history of the family remains unanswered.

1. Four remarkable new species of Caryophyllaeidae from the Anglo-Egyptian Sudan are described, three of which (from Siluroid fishes) are referred to a new genus, Wenyonia --W. virilis, W. acuminata, and W. minuta--and the fourth (from Mormyrus caschive) to the original genus Caryophyllaeus--C. filiformis. The chief characteristics of the new genus are the situation of the sexual apertures in the anterior half of the body, and the elongated uterus. The family Caryophyllaeidae, after deletion of the genera Diporus, Monobothriuin, and Glaridacris, thus contains three genera--Caryophyllaeus, Archigetes, and Wenyonia--all of which are re-defined, with their known species. 2. Very young immature forms of Wenyonia occur in the same (Siluroid) host as the adult and are devoid of a ‘caudal’ appendage, whence it would appear that the life-history of these new forms is different from that of C. laticeps. 3. The three families of the Cestodaria--Caryophyllaeidae, Gyrocotylidae, and Amphilinidae--are re-defined. 4. The Cestodaria, after eliminating Sanguinicola (a Trematode ?), are provisionally grouped into two Orders: the Amphilinidea (with one family, the Amphilinidae) and the Paralinidea (with two families, the Caryophyllaeidae and the Gyrocotylidae), the latter being closely allied to the Bothriocephalidae. These two Orders are defined.
