Diagnosis. — Inner surface of palm without oblique ridge. Abdo- 

 men of male very wide. Carapace subcylindrical. 



Description. — A larger species than U. stenodactylus. Carapace 

 longer in proportion to the width. Depressions shallow or obsolete. 

 Antero-lateral region less strongly curved downward. Front nearly 

 one-third width of carapace at antero-lateral angles, its marginal 

 carina well marked. Eyebrow shallower, invisible in dorsal view. 

 Carapace widest behind the blunt and obtuse-angled antero-lateral 

 •angles; side margins anteriorly straight and oblique; then faintly 

 marked by broken granulate lines. 



Large cheliped of male stouter than in U. stenodactylus. Merus 

 shorter than carapace ; granules of carpus few and scabrous ; those of 

 palm very coarse everywhere. Fingers little if any longer than palm, 

 moderately narrow, a longitudinal ridge runs along middle of the 

 pollex and is continued upon the palm ; several enlarged tubercles on 

 each finger. No oblique ridge across inner surface of palm, but the 

 surface distal to the carpal cavity is coarselj^ granulate. Merus of 

 first three pairs of ambulatory legs rather broad. Abdomen of male 

 very broad, all segments distinct.

 same 19 mm.
