The carapace is strongly calcified in front and submem- 

 branous behind the cervical groove, w^hich is deeply chiselled. 

 In the branchial region it is very broad and inflated. The 

 gastric area is convex from side to side and from the front 

 backwards ; its surface is smooth and glistening. On the hepatic 

 areas there are a few scattered granules, and a few tufts of short 

 setae are present on the line dividing the hepatic from the 

 gastric area. The rostrum is fairly w^ell developed and rounded 

 off. It does not extend so far forward as do the lateral pro- 

 cesses ; each of the latter bears a small tooth in front. 



The abdomen is of the usual form and is longer than the 

 carapace. The telson is only slightly asymmetrical. Its 

 posterior border is divided by a very deep and narrow indenta- 

 tion, and on each side of this there are three ,or four sharp 

 teeth. 



The eyestalks are short and thick, and are very much dilated 

 distally. The cornea - is large and deeply pigmented. The 

 dorsal area encroaching on the cornea is shallow and broad. 

 The ophthalmic scales are broad and rounded and are each 

 furnished w^ith a spine w^hich is attached just below the tip. 

 They bear fringes of short setae in front. 



When fully extended the antennular peduncle is about twice 

 as long as the eyestalks. The cornea does not quite reach 

 the base of the third joint, which is longer than the first and 

 second. It is considerably thickened near its distal end. The 

 upper flagellum is very slightly longer than the third pedun- 

 cular joint. The lower flagellum is about half as long as the 

 upper. 



The cornea reaches almost to the middle of the fifth joint of 

 the antennal peduncle. The outer process on the second joint 

 reaches the middle of the fourth. Its edges are entire. There 

 is a sharp tooth at the inner anterior end of the second joint 

 beside the base of the acicle, which is curved and tapering and 

 reaches to or slightlv bevond the end of the cornea. The third
