broad, and the lateral angle projecting slightly in advance of the jjost- 

 orbital tooth. 



Chelipeds t?ith the carpi externally granular-rugose, and with a 

 deep groove along the outer margin next the articulation with the 

 hand; hands a little unequal, slightly rugose above; fingers slender, 

 deflexed, with slight impressed lines, and slightly and obtusely toothed 

 within, the dactylus in the larger hand having usually a larger tooth 

 at the base. Ambulatory feet slender and pubescent along the 

 edges. Fingers black, lighter at the tips, the color not spreading 

 upon the palm. 



Length of carajiax in a male, 15.0 millim.; breadth, 22.5 millim. ; 

 ratio, 1:1.50.

Carapax slightly convex in an antero-posterior direction, but not at 

 all transversely ; antero-lateral border slightly upturned, so that the 

 points of the teeth ai'e nearly, or quite, on a level with the middle of 

 the carapax; areolations well marked, and the regions somewhat pro- 

 tuberant; microscopically granulous on the margins, and with a few 

 very slight transverse rugas. Front slightly prominent, nearly liori- 

 zontal, the edge thin, with a minute median incision, and the latei-al 

 angles projecting as narrow obtuse teeth. Incisions of the superior 

 margin of the orbit well marked. Post-orbital tooth small, trian- 

 gular, and separated from the second tooth of the antero-lateral 

 margin by a rounded sinus; remaining teeth rather prominent, trian- 

 gular, thickened along the anterior edge, and with sharp depressions 

 running back upon the carapax between their bases. Postero-lateral 

 border crossed by a slight depression. Inner angle of the inferior 

 margin of the orbit projecting into a prominent sharp tooth, outside 

 of which the edge of the orbit is thin, straight and not prominent. 

 External hiatus of the orbit a deep, acutely triangular notch. Tuber- 

 cle of the sub-hepatic region very small and close under the margin 

 of the carapax. 



Chelipeds with the carjji rugose externally, and with a deep and 

 narrow groove along th6 anterior margin of the outer side; hands 

 unequal, with a slight double carina along the upper edge; lar<'er 

 hand stout, fingers short, widely gaping, irregularly toothed within, and 

 with a stout tooth at the base of each finger, the one on the dactylus 

 shutting just within the other; smaller hand with the fingers slender,
