470 Rev. Canou Norman — A }fonth on 



Unciola leucopes (Krojer). 

 Is not Kroyer's species, but U. planipes (Norman). 



lltfperta tenulformis (B. & W.) and H. prehensilis (B. & W.). 



Bovallius retains both these species provisionally in his 

 genus Hyperoche^ Bate and Westvvood's- descriptions being 

 very imperfect *. 



Themisto crassicornis (Kroyer) , = Euthemisto lihellula 

 (Mandt). 



I have to thank the authorities of the British Museum, and 

 more especially Prof. F. Jeffrey Bell and Mr. R. I. Pocock, 

 for the valuable aid they have given me in going through the 

 type collection there.

* By the kindness of Mr. E. T. Allen, Director of the Marine Biological 

 Laboratory, Plymouth, I have been allowed to see what remains of 

 Spence Bate's type spirit-specimens of this species. Unfortunately these 

 have been at some period allowed to dry up, and are in such bad con- 

 dition that it is not easy to identify them. The fii-st and second perseopods 

 and one gnathopod are, however, in fair condition, and these agree with 

 Hyperoche Liitkeni (Bovallius, 1887). In another tube of Spence Bate's 

 Cullection marked ^^Lestrigonus, sp.," there are, besides five or six specimens 

 of H]iperia galba (Mont.) male, three male specimens of H. Liitkeni in 

 excellent condition, which shows at least that Bate had taken this species. 

 It may therefore fairly be assumed that Hyperia taurifonms (Bate) is 

 identical with Hyperoche Liitkeni (Bov.). But Sars holds that this 

 species is identical with H. Kroyeri (Bov., 1885), a name which replaces 

 Metacus medumriim (Fabrieius), en-oneously given by Kroyer. As 

 Bate's name is older than either of Bovallius's, this species should be 

 called Hyperoche tauriformis (Bate & VVestw., 1868). There appears to 

 be no trace of a type .specimen of Hyperia prehensilis (B. & W.), a very 

 doubtful species.
