the posterior börder of tlie basal segment of telson. The distal 

 lamella of telson not quite but nearly twice as broad as long 

 and witli rather square outer margin, but well rounded on 

 the sides. Anterior process of epistoma subtriangular with 

 rounded angles. Basal segments of the antennte provided 

 with hairs on the inner sides but no spines. The length of 

 the antennse equals that of the body from rostrum to telson. 

 Antennal scales shorter than the peduncle, about eqnal to 

 rostrum, very broad, broadest a little above middle, narrowed 

 to the base. The exteriör margin nearly straight, the anterior 

 rounded and fringed, the interiör converging to the exteriör 

 towards the base, nearly straight and fringed. The exteriör 

 margin ends in a short tooth. Third pair of maxillipeds hairy 

 within. Chelipeds slender, chelse subcylindrical, strongly gra- 

 nulated or covered with small tubercles and with a few fine 

 hairs upon it. Fingers about as long as the hand, granulated 

 and hairy, more hairs at the tips and on the insides or opposed 

 margins. Opposed margins of fingers straight, provided Avith 

 one tooth each, that of the movable finger situated nearer the 

 hand, but even the one on the immoval)le finger situated on 

 the proximal half of the same. Carpus granulated, with two 

 stronger spines below. Brachium granulated with three or 

 occasionally two anteapical spines on the inner side below and 

 one on the outer; two rows of smaller spines along the brachium 

 beneath. The hooks on the third segment of third and fourth 

 pair of legs not very strong. On the basal segment of fourth 

 pair of legs there is a rather large interiör tubercle. On the 

 basal joint of the fifth to6 there is a little tubercle. but it 

 is much smaller than the coiTesponding one of C. AUeni for 

 instance which species has no tubercle on the basal joint of 

 the fourth. First pair of abdominal legs moderate, not bifid 

 or provided with large teeth at the tip, tvvisted so that on 

 the anterior part the inner side is better developed, in the 

 posterior part the outer. The margins are sparsedly fringed 

 with fine, small hairs. Eyes and eyestalks rudimentary forming 

 together short blunt cones. Here are the dimensions of two 

 individuals :
