 teriorly, nearly smooth posteriorly ; no epibranchial spine ; front tri- 

 angular; carpus twice as long as wide, covered with large rough gran- 

 ules and small tvibercles, anterior margin unarmed or with a few spinules, 

 margins subparallel; outer margin of manus with a low crest; merus 

 of walking legs unarmed. 



Description: Carapace covered anteriorly with rough granules, 

 forming small tubercles on protogastric, hepatic, and epibranchial re-
