the carapace is as narrow as the front. The abdomen is not 

 twisted but is straight and slender. The fourth and fifth 

 pereiopods and the uropods are pressed closely to the body, 

 and the chelipeds are more nearly equal than in specimens 

 living in spiral shells. These individuals are all of small size 

 measuring from 9 to 15 mm., from the rostrum to the end of 

 the telson.

The centre of the frontal margin of the carapace is not pro- 

 duced into a distinct rostrum but is rounded off. The lateral 

 processes are also rather blunt. There are numerous radial 

 groups of setae on the carapace, especially on the hepatic and 

 branchial areas. The cervical groove is deep and distinct. 



The abdomen is of the usual spirally twisted form and is 

 rather slender. The telson is slightly concave on the hind 

 margin, which is lined with small teeth. 



The eyestalks are long and slender, slightly expanded at 

 at the base, narrow in the middle, and more distinctly ex- 

 panded towards the distal end. They reach nearly to the 

 tip of the antennal peduncle, and to about the middle of the 

 third joint of the antennular peduncle. The hind dorsal edge 

 of the cornea is sharply but not deeply emarginate. The 

 ophthalmic scales are rather small, blunt at the end, and hol- 

 lowed out on their dorsal surface. A strong spine is inserted 

 on the lower surface of each scale just below the tip and 

 slightly towards the inner side. There are a few small bunches 

 of hairs on the inner upper surface of the eyestalks, and a 

 fringe of stiff setae on the anterior edge of the ophthalmic 

 scales. 



The first joint of the antennular peduncle is short and thick, 

 the second is scarcely longer, but the third is much longer 

 than either, is slightly dilated distally and bears a sparse 

 covering of setae. The upper flagellum is slightly shorter 

 than the third peduncular joint. 



The outer process of the second joint of the antennal 

 peduncle is strong, bears only one or two teeth on its inner
