The first pair of gnatliopods are robust, the ischium has 

 an anterior lobe, the merus is short and wide, with a small 

 distal spine behind, as also has the wedge-shaped carpus and 

 the propodus; the dactylus is robust. The remaining legs 

 are robust, with a few spines, but with the furry pads on 

 the usual joints. The dactyli are well developed in all. 



The endopod of the first pleopod is considerably longer 

 than broad, thickened on its inner margin, with the out-er 

 margin slightly insinuate, but with a proximal angle or pro- 

 jection. The exopod is much larger, although reaching the 

 same distance as the endopod; it lies obliquely, and the 

 fringes of both are long. The outer end of the peduncle of 

 this limb narrows out somewhat. In the second pair the 

 exopod is much shorter and smaller than the endopod ; the 

 appendix exceeds the length of the endopod, including its 

 fringe; there is a short ridge on the inner side of the endo- 

 pod. The third pleopod has the peduncle much longer at 

 its inner side ; the exopod is divided near its end. 



The uropods are lamellar, subequal in size, rounded on 

 their distal margins, the outer one being slightly concave 

 above. 



The two processes of the seventh sternite of the thorax 

 are short. 



This species, represented by only one male, is from 

 Denial Bay, and was collected by Drs. Verco and Torr in 

 January, 1908.

This species is the type of the genus, and is here noted 

 for purposes of comparison. 



The body is shaped typically, being somewhat vertically 

 compressed, with the head gradually declivous and narrow- 

 ing considerably, and is very like C. acuticaudafa, Haswell ; 

 in fact, the females are hard to distinguish from those of 

 that species. 



The posterior notch of the pleon in the male is deep, nar- 

 row, widening inwardly, the median process slightly raised, 

 broadly triangular, obscuring the base in a dorsal view, not 

 projecting as far as the arms of the notch, which are ter- 

 minally obtuse. 



The distal end of the first joint of the antennule has the 

 posterior limb of the notch curved, and projecting much 

 more than the anterior limb, but not quite reaching the end 

 of the second joint. 



The exopod of the first pleopod has 11 strong teeth.
