44 AXEL OHLIN, ARCTIC CRUSTACEA. 



points out^ that Spence Bate's description is contradictory 

 in one essential character, and even incorrect in another. 

 For this reason he does not find it appropriate to maintain 

 that genus. 



In a paper of Ortmann, published in Princeton Univ. 

 Bulletin last year and cited by Doflein, I find that this 

 author also adepts Spirontocaris and that he includes in this 

 genus: HippoJyte Gaimardi, H. Phipp>ii (= H. turgida), H. spi- 

 nns, H. polaris {— H. horealis, which Ortmann eonsiders as 

 specifically distinct) and H. groenJandica. 



In this list, where only a few species have to be enume- 

 rated, I refrain from a critical study, for want of time and 

 material, and I retain, therefore, the old name in the hope 

 that a monograph of the family may soon appear. It has 

 been promised by Doflein.
