Carapace somewhat transversely oval, but much contracted poste- 

 riorly, flat, somewhat hahy, with no trace of regions. Fronto-orbital 

 5order not much less than greatest breadth of carapace. Front 

 profusely spinate, the spines being sharp and a little curved. The 

 mtero-lateral borders pass backward with but little outward slope, 

 I little shorter than the concave and . convergent postero-lateral 

 jorders, and armed with a number of sharp curved spines. The 

 )rbits are at antero-lateral angles of carapace and do not conceal the 

 ;yes; their edge shows no fissures nor sutures; their upper and lower 

 nner angles are broadly in contact, or almost in contact, so as to 

 sxclude the antennae. The antennules fold nearly transversely, 

 rhe basal antennal article hardly reaches the front, though its outer 

 mgle is produced toward front; the flagellum is short, hardly as 

 ong as orbit. Buccal cavern broad; crests of endostome not very 

 ;trong, nor is the foliaceous process of first maxillipeds produced 

 "ar forward; external maxillipeds very long, merus remarkably broad 

 md short. Chelipeds somewhat unequal, short, and not very 

 nassive; arm almost entirely hidden by carapace; fingers compressed, 

 jointed. Legs stout, especially meropodites. The abdomen of the 

 nale has all seven segments distinct and separate. 



Both sides of tropical America; Indo-Pacific region.

Diagnosis. — Carapace much narrowed behind. Carapace and 

 ihelipeds armed with black spines. Merus of outer maxillipeds very 

 5hort. Fingers compressed and pointed. 



Description. — Carapace covered with light-colored hairs; antero- 

 ateral border with four to six (including orbital angle) acute dark- 

 tipped spines, and several similar spines on carapace just inside 

 mtero-lateral border, and also just inside spiny fronto-orbital border. 

 Upper orbital margin and prominent edge of the epistome finely den- 

 ticulate; lower orbital margin spinous. Merus of external maxillipeds 

 extremely broad and short, with an elevated patch of denticles on 

 Duter surface. Chelipeds unequal; arm, wrist, hand, and dactylus
