Eyes round. First pair of gnathopoda smaller than the second ; 

 second pair ha^•ing the propodos with the palm notched near tlie 

 distal extremity. Posterior pair of pleopoda not reaching beyond 

 tlie extremity of the preceding. Tclson broad at the base, 

 narrowing towards the middle, then continuo\is in the form of a 

 prolonged ape.x. In all other characters the animal bears a close 

 resemblance to L. articxdosa.

" Lai'ge, robust, thick. Coxoe very small. Cephalon depressed 

 below the fii'st segment of the pereion, subquadrate, \x\i\\ a slight 

 rostriun in front, between the superior antennae. Eyes large, on 

 the sides of the cephalon. Mandibles \Adth a minute triarticulatc 

 appendage. JMaxillipeds slender, freely projecting. Supeiicn- 

 antennoe -n-ith the peduncle very thick and elongated ; flagellum 

 short : infefior pair aiising some distance below, and much more 

 slender than, but about as long as the superior, which are about 

 one-fourth the length of the body. In the first pair of gnathopoda 

 the meros is very minute ; the carpus subquadrate, compressed, 

 \\-ith its inferior apex produced into a slender process, of efpial 

 length with the propodos, which is very much elongated, slender, 

 and bears a slightly curved dactylos, which overlaps the produced 

 extremity of the carpus for nearly half its length. In the second 

 pair of gnathopoda the cai^pus projects over about half the inferior 

 margin of the propodos, which is thick, ovate, and of great .size, 

 equalling in length more than the first three segments of the 

 pereion ; dactylos strong and curved. The pereiopoda arc rather 

 long, but very slender, with short dactyla. Three posterioi- ])airs 

 of pleopoda long, slender, nearly smooth, and pointed. Colour m
