276 CRUSTACEA. 



The genus Lupocyclus of Adams and White (Crust. Samarang, p.

Carapax areolate, sparingly transverse, nude, granulate, front between 

 the antennae five-toothed, the median tooth very minute triangular, 

 the next either side not at all prominent, the next prominent,

Length of carapax, eight lines ; greatest breadth, eleven and one-
