pace ; those on the mesogastric region smaller and more broken. The 

 paired submedian lines of the telson are transverse, almost straight. 

 The chelipeds are of moderate size ; the merus short, appressed to the 

 body, a spine at the inner, upper distal angle ; the carpus is about as 

 long and as wide as the merus, subcylindrical, with a spine midway 

 the inner lateral margin, and another spine at the inner distal angle. 

 The propodus is nearly three times as long as the carpus, the palm 

 being two-thirds of this width, the fingers comprising the remaining 

 third. The propodus is of no greater width than the carpus, with the 

 outer face moderately convex ; both the carpus and the propodus have 

 the outer faces crossed by small striae similar to those on the carapace. 

 The fingers are similar, straight, meeting throughout their entire 

 length, neither with a large tooth. In the type, the left cheliped is 

 distinctly larger tJian the right, but this is very obviously the result 

 of an accident to and the regeneration of the right claw. 



The second, third and fourth pairs of legs are similar, slender, each 

 with the propodus elongated, the dactyl scarcely half as long, very 

 curved and acuminate. 



The fifth legs are small, slender, weakly chelate, reflexed in the 

 usual manner. 



The type is a female, carrying about thirty spherical eggs; the 

 eye-spots showing in the embryos.
