Meastirements. — Length of carapace to end of rostnim, 11.7; width 

 across front and orbits, 5.6; -width between antero-lateral angles, 

 13.5 ; width between postero-lateral angles, 12,8. 



A large part of the carapace is occupied by the lateral wings which 

 extend from the orbit nearly to the posterior margin and are divided, 

 not very deeply, into two very unequal parts. These wings, which 

 are ovitwardly ascending, are separated from the body proper by a 

 shallow furrow. The mesogastric and the cardiac region are each 

 surmounted by a blunt, conical elevation, the latter the higher ; each 

 protogastric lobe bears a low elevation forming an equilateral tri- 

 angle with the mesogastric tubercle. The posterior margin has a 

 thin, narrow, suberect border. While the surface appears smooth 

 to the naked eye, it is really microscopically granulate. Rostrum 

 deflexed and cut halfway back into two small triangular teeth sepa- 

 rated by a triangular sinus. On either side is a larger subtriangular 

 preorbital tooth, in the postero-lateral angle of which is cut the 

 small semicircular orbital margin. Eye immovable, very little of it 

 visible from above; seen from below the eye-stalk appears flat and 

 about one and a half times as long as wide; pigment dull-colored in 

 alcohol. Anterior margin of antero-lateral wing sinuous, with a 

 sinus near the angle and a faint trace of a tooth at the inner fourth. 



Basal segment of antenna distally tapering and having a very 

 small tooth at the outer distal angle; next two segments slender, 

 the second one and a half times as long as the third; the flagellum 

 is subequal in length to the free peduncular segments and exceeds 

 the rostrum. Buccal cavity very small, widening a little distally; 

 exognath of maxillipeds half as wide as ischium of endognath * merus 

 wider than ischium, expanded at the antero-external angle. 



Chelipeds a little longer than carapace; merus, carpus, and manus 

 cristate above, merus with a terminal tooth, carpus with tubercle on 

 inner surface, dactylus bicristate above ; fingers with a wide gape in 

 proximal half, a large tooth on the dactylus, in the gape; meeting 

 edges dentate. The legs diminish rapidly in length; their margins 

 are cristate; merus and carpus each with a large tooth at end of 

 upper margin; propodus with a smaller subterminal tooth, and in 

 the first pair with a still smaller tooth at the middle; in the first 

 pair the merus also has a small tooth at the middle.
