Ocular peduncles short, stout at base, gradually narrowing to the 

 black cornea; surface partly granulous, some spines on the summit. 

 The antennules can fold wholly under the front ; when so placed their 

 second article is inside the eyes, parallel to frontal border, conceaUng 

 the last peduncular article which is folded below it. Basal article in 

 form of a rectangle rounded behind ; armed inferiorly with numerous 

 spinules, especially forward; it is almost in contact, on median line, 

 with the corresponding article of the opposing antennule. First 

 article of antennae entirely smooth, appearing to be a prominence of 

 the epistome; next article elongate-quadrangular and a little bent; 

 it has a strong spine at antero-extemal angle and on its lower surface 

 a number of spinules; flagellum scarcely longer than second article; 

 it is composed of three or four articles, the last furnished with two 

 hairs longer than the whole flagellum. Ambulatory legs 1 and 2 

 covered with many strong spinules; at their base sometimes 3 or 4 

 arranged in a group. (After Milne Edwards and Bouvier).

Diagnosis. — Carapace widest in front of middle. Cornea light 

 brown. Merus of outer maxilhpeds suboval, outer margin arcuate, 

 longer than inner. 



Description. — Carapace widest at the middle, sutures very distinct; 

 gastric pentagon reaching to a point on the basal half of the rostrum; 

 cardiac region wide, prolonged on the posterior branchial areas. On 

 the dorsal face of the carapace, most of the projections resemble 

 large granules, but three or four are stronger and form conical promi- 

 nences on each epigastric lobe ; others become equally long and strong 

 on the anterior lobe of the branchial area, and form there some obtuse 

 spines or one or two more conical protuberances. The deflexed sides 

 of the carapace are rough with obtuse and arcuate spines up to the
