Delia Valle makes it clear, in my opinion, that the above 

 species cannot be the Lysianassa Costce, H. Milne-Edwards. 

 Tiiat species is too imperfectly described and figured to be 

 recognizable ; but it can scarcely be our northern species, as 

 here understood — -^rst, because the third segment of the meta- 

 some is not produced in hook-like form ; seconS/y, because it 

 was found among seaweeds at Naples ; and Delia Valle has 

 not met with anything like our northern Lysianassa at 

 Naples. He thinks it possible that M. -Edwards's species 

 may be the same as that which he has himself described 

 under the name Lysianassa bispinosa. 



* Judging by the telson, the figures of the entire animal and of the 

 urosome cannot have been taken from this species. Vidi' Walker, Ann.
