There are no indications of processes on the anterior por- 

 tion of the abdomen ; the abdomen itself is minutely granulate, 

 and close to the posterior margin the surface is flattened 

 or slightly turned up. The exit to the moderately deep longi- 

 tudinal channel is open, and two faint insinuations of the 

 margin are all that there is of a notch. 



The uropods are reduced, scarcely compressed, and 

 slightly rough ; each inner ramus is tipped with a small tooth, 

 and the outer rami, which are shorter, are slightly bifid. 



The outer surface of the basal antennular joint bears a 

 row of small spinulate granules : but there are no teeth, nor 

 are there rostral or epistomial teeth. 



The mouth parts are modified, but not strikingly so ; the 

 palps of the maxillipeds bear long lobes, but they are desti- 

 tute of setae. 



The epistome is rounded and rather swollen anteriorly, 

 and is setose. 



The legs are slightly less robust than in the male. 

 A supposed immature male of this variety resembles much 

 that of C. tuberculosa — except again in size. The body is 

 rather more elongate, and apparently budding processes are to 

 be found on the anterior portion of the abdomen. 



There are no indications of rostral, antennular, or epis- 

 tomial teeth. 



The uropods are laminate and rather abruptly acu- 

 minate. 



The posterior portion of the abdomen is very obtusely 

 pointed, with the exit of the channel almost vanishing. 



The epimera of the second, third, and fourth thoracic 

 segments are more narrowly pointed. 



The posterior angles of the thoracic segment are similarly 

 truncated, as in C. tuberculosa. 



Budding sternal filaments are present, but there is no 

 apye n dix masculina . 



In the collection there is one immature female similar 

 to this. 



I have figured an immature male, which I think should 

 be placed here (plate xxxii., figs. 3, 6, and 7), with a slightly 

 different abdomen and with epistome more like that of the 

 mature female recorded above ; this one, it will be seen, has 

 a more pointed abdomen with commencing processes on the 

 anterior portion, with small tubercles near them ; the channel 

 also is similar to the mature female, except that the insinua- 

 tions of the margin are not present. The sternal filaments 

 are moderately long.
