half of its dorsal surface and along the outer edge, while the inner edge bears a 

 pair of rather large sj^ines ; the hand is spinulate everywhere in the smaller 

 cheliped, but only in the proximal third of its outer surface in the larger ; the 

 fingers also of the smaller cheliped are spinulate on the outer surface, while those 

 of the larger cheUped are smooth ; the cutting-edges of the fingers are finely 

 and unevenly toothed. 



The other thoracic legs are long, compressed, and slender, and have the 

 meropodite spiny along both edges, the carpopodite and propodite spiny along 

 the front edge, and the dactylopodite styliform. 



Colour in the fresh state yellowish red.

Carapace broad, approaching the quadrilateral, convex fore and aft, the 

 branchial regions so inflated and convex dorsally as to make the transverse plane 

 of the carapace strongly concave in the middle line, the other regions obscurely 

 defined, the surface smooth. 



The antero-lateral borders are very much shorter than the postero-lateral, 

 are very thin and sharp, and are cut into teeth of which the first is confluent with 

 the outer orbital angle. 



Front broad, a third the greatest breadth of the carapace, straight, square 

 cut, slightly projecting beyond the supra-orbital angle, from which it is sharply 

 cut off by an angular notch, on either side. 



Orbits large, with a thin, sharp, prominent margin ; a notch internal to the 

 middle of the upper margin, the notch breaking this margin into two curves, one 

 corresponding to the eye-stalk the other to the cornea : eyes large, reniform, on 

 moderately stout stalks. 



Antennules folding transversly. The basal antenna-joint is very short, 

 but almost touches the turned down side-edge of the front : the flagellum, which 

 is considerably longer than the major diameter of the larger orbit, springs from 

 the rather broad orbital hiatus. 



The buccal cavern is broader anteriorly than posteriorly, and the mouth 

 parts do not nearly reach its front edge, so that a wide and permanent gap is left: 

 the crests of the endostome are not very strong, but the free edge of the endo- 

 stome corresponding to the efferent branchial channel, on either side, is deeply 

 excavated. The outer wall of the efferent branchial canal forms a strong angular 

 bulge in the pterygostomian region.
