ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 207 



Notes on Bothriocephalidse.* — Herr M. Ltihe discusses Bothrio- 

 cephalidge with marginal genital apertures, and in particular Abothrium 

 fragile (Rud.) ( = Bothriocephalus fmgilis Rud.). Fislulicola (g. n.) 

 plicatm (Rud.) ( = B. plicatus Rud.), Anchislrocephalus imbricatus (Dies.) 

 (= Diboihrium imbricatwm Dies.), and Trisenophorus nodulosus (Pall.) 

 Rud. (= Taenia nodulosa Pall.). 



Cestodes in Birds. — Herr O. Fuhrmann describes t two remarkable 

 forms — Gyrocoelia perversus g. et sp. n., notable for the absence of a 

 vagina, and Acoleus armatus g. et sp. n., also without a vagina, with a 

 peculiarly formed receptaculum, and with an unusual disposition of the 

 musculature. The hosts were Himantopus autumnalis and Limosa rufa. 

 He also discusses t Taenia crateriformis and T. muscnlosa, which he 

 proposes to include in a new genus Monopylidium, beside Oochoristica, 

 Davainea, &c. Herr K. Wolff hiigel § criticises Cohn's proposed syste- 

 matic arrangement of the Cestodes from birds, maintaining that it is 

 much too soon to attempt this with success. 



Genus Rhopalias.|| — Herr M. Braun has some remarks on this 

 apparently isolated genus, which was founded by Diesing as Bhopalo- 

 phorus for two flukes found in JDidelphjs, and emended by Hassall. 

 Braun has studied very many specimens belonging both to the species 

 recognised by Diesing, and to a new species, and finds that all show a 

 close internal resemblance to typical Echinostomse, which makes the 

 possession of the two characteristic bristle-crowned proboscis-like struc- 

 tures all the more remarkable. But careful examination shows that in 

 Bhnpalias coronatus a double row of bristles connects the orifices of the 

 proboscides, and recalls the bristle-bearing disc of the Echinostomes. 

 There can be no doubt that the Bhopalias-con&ition can be derived from 

 the Echinostome, from which the species must be supposed to have 

 arisen. The observation thus deprives Bhopalias of its apparently 

 isolated position. 



Trematodes of Egypt.l — Prof. A. Looss describes a large number of 

 new forms, many of which require new genera. He breaks up the genus 

 Distomum into numerous sub-families. The general classification recog- 

 nised is the following : — 



A. Aspidocotylea. 



B. Malacotylea. 



Metastatica, Fam. Holostomida3. 

 Digenea s. strict., Fam. Distomidte. 



„ ? Rhopaliadae. 



„ Schistosomidag. 



„ Gasterostomidfe. 



„ Didymozoonidpe. 



„ Monostomida?. 



Studies on Distomidse.** — Herr S. Jacoby describes some peculiar 

 species of Distomum : — (1) D. heterolecithodes Braun from Porphyrio
