duced ; frontal line slightly wavy ; superior orbital margin with three 

 sutures, angles rounded, obscure; pterygostomian region swollen, in 

 young ornamented with a large granule which sometimes simulates a 

 tooth, this becomes less obvious with age. The cervical, urogastric, 

 and particularly the intestinal grooves are very sharply defined in 

 young specimens. In the young there are a number of large, rounded 

 granules covering the surface of the carapace ; these are much smaller 

 on the frontal region. In older these tubercles disappear or become 

 much smaller and scattering. The posterior, or intestinal region, is 

 elevated, dome-like, ornamented on the posterior margin with a pair 

 of submedian spines, each of which is below and in line with the lateral 

 part of the sulcus which circumscribes the intestinal region ; outside 

 of these is a lateral pair of tubercles which are as far, or slightly more 

 or less so from the median tubercles, than these latter are from each 

 other. 



The chelipeds are typically Leucosid; the merus in the female is 

 two-thirds as long as the carapace is wide; in the male it is slightly 

 longer ; cylindrical, granulose in the young, less so in the older speci- 

 mens; the propodus is somewhat swollen, the fingers slender, curved. 



The ambulatories are typically Leucosid.
