like those on the hand. The legs of the second and third

 short spines on their superior border. The legs of the

There is no rostrum on the frontal border; the 

 ophthalmic scales are widely separated, and the antennular 

 peduncles, well developed, exceed the eyes, and are almost 

 as long as the carapace. The external antennae have on 

 the second joint a prolongation in the form of a toothed 

 spine ; the flagellum is not as long as the first pair of legs. 

 The legs of the first pair are of equal size, and the hands 

 can be placed at a right angle with the carpus ; their inner 

 edge is more or less straight, so that when placed along- 

 side its companion they form a closed door ; the fingers 

 move in a horizontal plane. The abdominal rings are 

 calcified above and below, but are membranous along the 

 side; the first six rings have each a pair of appendages, 

 and the terminal ring ends in a flat process divided in two 

 by a transverse hinge, its terminal part being two hinged 

 lobes. The biramous legs of the sixth segment have a 

 rasp-like arrangement on the external face of the two 

 branches. 



The one specimen found lived in a hole in a stony 

 substance, and was able to close the entrance by its two 

 hands placed side by side. 



Range. — West Indian Sea; in deep water.
