Like the foregoing the present species is broader than long, the breadth of the carapace 

 being 1.3 times its length, according to Bürger's measurements, and even 1.45 times the length 

 in my specimen. Burger observed that the front is rounded and httle prominent; indeed I 

 stated that its anterior margin is regularly convex and does not present the triangular lobe, 

 curved backward, commonly met with in Pinnotheres. Jhe whole carapace is perfectly glabrous, 

 shining, very thin and flexible ; its posterior margin is quite straight. 



The dactyhis of the external maxiUipeds reaches exactly to the end of the propodus. 

 Tlie walking legs are hairless and thinner than in the preceding species; save for the 

 dactyli, all legs are of nearly equal length. The dactyli are not flattened and slightly curved ; 

 those of the i^' and 2'^ pair are of equal length, about one-third the length of the preceding 

 propodites, those of the 3^^ pair are of similar shape, but twice as long as in the 

 preceding pairs, in the last pair the dactyli are more slender, hairy along inner margin 

 and 3 times as long as those of 2^^ and i'^' pair^). 



The eggs of the ovigerous 9 are most numerous and of the same diameter as in the 

 preceding species.

I am not quite certain about my determination, as Bürger's figure does not quite agree 

 with mine. In the original specimen the carapace is more distinctly hexagonal and the ej'es are 

 not visible in dorsal view ; in my specimen the carapace is more narrowed anteriorly, the 

 anterior angles of the carapace being nearer to one another and very distinct, and the rounded 

 eyes are shining through the supra-orbital margin. As to the chelae, Burger says that the 

 palm is scarcely twice as long as the fingers, though it does not seem so in his figure; in my 

 specimen the palm is about iYjj times as long as the fingers (fig. 4^) and the latter are each 

 provided with a distinct, oblique tooth, that of the fixed finger being placed nearer to the tip 

 than its antagonist. Some disagreement also exists in the external maxillipeds, the propodus 

 of which is narrowed distally in Bürger's figure, but not so in my specimen (fig. \d). Burger 

 does not say much about the walking legs; from his figure we learn that the dactyli of 3'^ and 

 4"^ pair are equal in length and longer than those of the preceding pairs. In my specimen the 

 first three pairs of legs are subequal in length, and the last pair much shorter and weaker ; 

 the propodites are hairless; dactyli of i^^ and 2'' pair short, strongly hooked, hairless and 

 perfectly alike; these of 3"^ and 4"' pair are much more slender, regularly curved, twice as 



l) Bürger's measurements indicate, however, that the dactyli of the 4<h pair are not yet twice as long as those of the 2^ pair.
