CANCROIDEA. 949 



This species has the areolet 2 L 3 L very distinct, and this character, 

 together with the transverse ridgelets, hirsute anterior legs, and gene- 

 ral form, distinguish it from the R SmitML One of the ridgelets or 

 rug£e extends inward, nearly transversely (inclining somewhat for- 

 ward) from the penult lateral spine; another interrupted range crosses 

 the carapax by the front of 2 M, another by the front of 1 M, and a 

 minute range marks the anterior limit of 2 F. The marginal teeth 

 have often a spine on the posterior side. From the spinifrons it differs 

 in having the teeth of the front quite minute, and the hands and 

 carpus thickly armed with spines, as well as pubescent. Moreover, it 

 is broader for its length. The postero-lateral margin is rounded. 

 The large oblique basal tooth of the moveable finger is alike in both 

 sexes. There is a spine on the lower margin of the orbit, inner side.

 areolate in any part, granulous; front between the antenna two-
