SCHiZOPODA, STOMATOPODA, AND NON-ANTAKCTIC ISOPODA. 893 



body is distinct throughout, and there is no cordon for the support of the male. The 

 pleon in the female is terminated by a pair of biramous uropods, not uniramous as 

 figured by Sars. In this respect the species diifers from the genus Dajus, to which 

 it was referred by Sars, and it is possible that this diiference may, in the future, be 

 thought worthy of generic significance; but I do not feel able at present to go into 

 the matter fully, as I have not enough material for the purpose. I do not know of 

 any other genera of Dajiidse in which the uropods of the female are biramous. 



The adult male has the pleon unsegmented, narrow, pointed, and slightly curved, 

 and terminated by a pair of uniramous uropods. 



Both the adult male and the Cryptoniscan larvae are characterised by the excessive 

 development of dark pigment, so well illustrated in Sars' figure. This feature enables 

 the larvae to be identified in tow-net gatherings.
