534 ZOOLOGY OF THE FAR EAST. 
This species appears to be distinguished from C. brazieri Haswell of Australia by 
having the two branches of the third uropods equal in length. 
Walker has recorded C. pusilla from Ross Sea, in the x\ntarctic, especially 
mentioning that the branches of the uropod were of equal length, and that the 
specimen could not, therefore, be referred to C. brazieri. 
Distribution. North Atlantic, Mediterranean, Malay, Antarctic (Ross Sea).

A few specimens. 
These specimens appear to be quite the same as those from the Chilka Lake 
referred to this species.

This species seems to be quite abundant at Tale Sap and was obtained from 
several different localities, the specimens presenting no appreciable difference from 
those of the Chilka Lake. 
Distribution. Tale Sap ; Chilka Lake ; Zanzibar.

Only one male .specimen of this species was obtained, probably not fully 
developed, but it appears to be quite the same as the form found in the Chilka Lake. 
Several specimens were taken which I feel pretty certain must be the female 
of this species, which had not been recognised before, as the specimens from the 
Chilka Lake were not numerous and those examined proved to be males. In these 
specimens the antennae are similar to those of the male, but the tuft of setae at the 
end of the second joint of the first antennae is wanting, the first gnathopod 
is slightly more slender than in the male, and does not show the special modification 
of the meral joint. The second gnathopod differs very con.siderably from the
