[No. 2, 
rostrum is formed of two styliform divergent horns. The supra-ocular 
border is armed with a horn similar to those of the rostrum, but 
directed more obliquely. The eye-stalks are slender, immobile and 
extremely salient; their length is half the greatest breadth of the 
body. The first joint of the antennae is much longer than broad, the 
second is slender and is inserted beneath the rostrum. 
The epistome is nearly square, and the external maxillipeds have 
the merus extremely dilated at the antero-external angle, and exca¬ 
vated at the antero-internal angle. The trunk-legs, in the female, 
are slender and cylindrical: those of the first pair (chelipeds) are 
hardly stouter and are much shorter than the second, which latter 
are a little longer than the carapace and rostrum : the others diminish 
very gradually in length : all the ambulatory legs have sharp, recurved 
dactyli. The abdomen of the female consists of five segments, the 
4th, 5th and 6th segments being fused together.” (Edw.)
