60 CARCINOLOGICAL STUDIES. 



portance between these specimens. I only observe that the 

 eye-peduncles of the Samoa-specimens are a little more 

 dilated at the distal end , and that the rostral plate is 

 slightly more transverse and has the small median spinule 

 comparatively a little longer than the specimen from the 

 Cape Verd. The terminal joint of the antennular peduncle 

 appears in the figure , published by Miers , to be about 

 twice as long as the penultimate one; but in reality, in 

 the Samoa-specimens , as well as in the Atlantic indivi- 

 dual the terminal joint is only a little longer than the 

 preceding one. 



The larger specimen measures a little more than 5 cen- 

 tim. in length. 



As we know, still another species of this genus appears 

 as widely distributed, occurring both in the Pacific and 

 Atlantic oceans , viz. : Pseudosquilla ciliata Miers , which I 

 consider to be specifically distinct from Pseudosquilla oculata 

 Brulle.
