ZOOLOaY AND BOTANY, MICROSCOPY, ETC. 237 



Of tlie Anthuridse there are four new genera — Cyathura, Anthelura, 

 Hyssura, and CalaiJiura. 



In a postscript reference is made to works published since 1884 ; with 

 regard to the species which forms the basis of Prof. Claus's memoir — 

 Ajpseudes latreillii — the authors point out that it is certainly not that 

 species as ordinarily understood, and they propose for it the name of A. 

 hastifrons ; two very important papers have also been published by Prof. 

 Sars. 



Diagnostic tables accompany the descriptions of the families and genera. 



New Isopoda.* — Mr. C, Bovallius, in two essays on new or imperfectly 

 known Isopoda, describes eight new species from various localities ; with 

 these, as with the previously named species which he re-describes, he 

 gives, when he can, descriptions of males, ovigerous and virgin females and 

 larvae. 



Asellidae.f — Mr. C. Bovallius, in his notes on the Asellidae, institutes 

 three new generic names with the object of getting more uniformity in the 

 system ; these are lamna, lath-ippa, and lais. A useful analytical table of 

 the genera is given. lais haryeii is the only species; the old ones are 

 carefully described and their synonymy fully given. 



AmpMpods.J — Dr. H. Blanc has described seventeen Amphipod forms 

 found in the Bay of Kiel. The memoir also contains a histological de- 

 scription of the calceoli or peculiarly shaped sensory organs found on the 

 antennee of many Amphipods. These were regarded by Sars, Leydig, and 

 others as olfactory organs, but the author is apparently inclined to attri- 

 bute to them an auditory function. The olfactory rods generally dis- 

 tributed on the anterior antenna are also discussed. 



AmpMpoda Synopidea.§ — Mr. C. Bovallius institutes a new tribe of 

 Amphipoda Synopidea, for the forms intermediate between the Gammaridge 

 and the Hyperiidea ; it is divisible into the three families of the Synopidse, 

 which are most closely related to the Gammarids, the Trischizostomatidse, 

 and the Hyperiopsidee. The constituent species, among which are two new 

 forms of Synopia, are very carefully described. 



Forgotten Genera of AmpMpoda. || — Mr. C. Bovallius has some notes 

 on Lanceola Say, which is not, as has been supposed, identical with Hyperia 

 or Vibilia; of this rare form five new species are now described; on Daira 

 Milne-Edwards, which is not identical with Dairinia of Dana, who changed 

 the name in consequence of Daira being preoccupied, but it is apparently 

 identical with Paraphronima of Glaus ; Clydonia Dana is identical with 

 Tyro M.-E. ., and as the latter name has priority it must be restored; five 

 new species are described. The distinctive characters of the genus Tauria 

 Dana are pointed out. 



Apus and Branchipus.lf — Herr Fickert points out as the result of his 

 observations that Branchipus may be found alone, but Apus only where the 

 former is also present. Branchipus is in fact the principal prey of Apus. 

 Kept together for a night in conditions where escape is impossible, the 

 weaker fall victims to the stronger. The nimble and transparent character
