In the paper last referred to full synonymy is given. It 

 lias since been described and figured by >Sars and by Delia 

 Yulle. In Norman's paper the changes with growth in the 

 second gnathopod of the male is illustrated. Delia Valle 

 describes three species of Elasmopus from Naples : are these 

 really true species, or are they different degrees of develop- 

 ment of one form ?

From observations made by Mr. A. 0. Walker on original 

 specimens in the British Museum, he has come to the con- 

 clusion that the type specimens of Pherusa fucicola, Leach, 

 are really the female of this species. The figure of Pherusa 

 fucicola in Bate and Westwood is stated to be taken from 

 one of these specimens, but is full of errors which make it 

 quite unrecognizable. On the other hand, Mr. Walker 

 contends that Bate's Pherusa fucicola of the (Jut. Amphip. 

 Brit. Mus. is drawn from an entirely different genus, and 

 must be referred to Aplierusa Jurinei, H. Milne-Edwards 

 (see Walker, " On Pherusa fucicola, Leach," Ann. & Mag. 

 Nat. Hist. ser. 6, vol. vii. p. 418). 



The name Pherusa fucicola. Leach, has not the slightest

claim for adoption. The description given by the author 

 was not only utterly inadequate but in part absolutely wrong, 

 so that no one could possibly have guessed what species was 

 meant.
