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

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

 That species is too imperfectly described and tigured to be 

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

 here understood — -Jlrst, because the third segment of the meta- 

 some is not produced in hook-like form ; secondly, because it 

 was found among seaweeds at Naples ; and Delia Valle has 

 not met with anything like our northern Lysianassa at 

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

 may be the same as that which he has himself described 

 under the name Lysianassa hispinosa. 



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

 urosonie cannot have been taken from this species. Tide Walker, Ann. 

 & Mag. Nat. Hist., Feb. 1892, p. 136.
