Female. — Body short and thick. Carapace less than two fifths the 

 length of the abdomen ; the anterior and middle portion of the carapace 

 is depressed and pubescent ; this depressed area is defined by a curved 

 line extending backward from the antero-lateral angle nearly to the pos- 

 terior margin on the median line, and is crossed in part by nine carinae. 

 The median carina is the length of the depression and is armed with two 

 spines, one at two fifths 



the distance from the *^^:5^^ ^ — ^^^ — '^^^^'~7^ 



posterior margin, the 

 other at an equal dis- 

 tance from the first. First 

 lateral carina short, ter- 

 minating in a spine half 

 way between the two 

 median spines. Second 

 lateral carina as long as the dorsal depression, and unarmed except for the 

 spine at the anterior end, which marks the outer angle of the orbit. Third 

 lateral carina short, terminating in a spine half way between the superior 

 lateral spine and the anterior median spine. Fourth lateral carina form- 

 ing the boundary of the depression and terminating in a spine at the 

 antero-lateral angle of the carapace. Rostrum short, reaching to a 

 Une between the tips of the orbital and the antero-lateral spines ; nearly 

 horizontal, medially sulcate, tip rounded. 



The scale at the base of the antennules is broad, has a straight outer 

 margin, and is tipped with a small spine. The first and second segments 

 of the peduncle have a blunt spine at the outer distal angle, that on the
