Diagnosis. — Size small. Carapace more than one and a half times 

 as wide as long. Lateral borders subentire, the teeth scarcely 

 projecting outward beyond the marginal curve. Antero-lateral 

 regions and wrist and palm eroded. 



Description. — Carapace more than one and a half times as wide as 

 long; deeply eroded along the antero-lateral regions, covered with 

 depressed granules and punctae elsewhere. Gastric and mesogastric 

 regions well delimited. Mesogastric region constricted before it 

 widens out; protogastric lobes partly subdivided. The oblique 

 branchial ridge does not extend to the antero-lateral margin. Sub- 

 median frontal lobes subtriangular, outer lobes smaller, triangular; 

 median sinus narrower than lateral ones. Above the margin of the 

 front a transverse ridge, giving the appearance of a double-edged 

 front. From this ridge the median groove leads backward. Inner 

 suborbital tooth small, inconspicuous. Antero-lateral border mar- 

 ginate, entire or subentire; the positions of three of the obsolete teeth 

 are indicated by short, oblique, dorsal ridges, but the teeth can best 

 be discerned from the ventral side. 



Carpus and manus of chelipeds eroded. Minor manus two-thirds 

 as high as major. The dark color of the minor fingers covers only 

 the distal half, of the major fingers reaches nearly to the proximal end. 



Color. — Wine-color or dirty rose forming a reticulated pattern with 

 lakes or spots of fawn-color. (Desbonne and Schramm.) 



Measurements. — Male (24354), length of carapace 15, width of 

 same 23.8, fronto-orbital width 9.2, width of front 6.2 mm. 



Range. — Bahamas; West Indies; north coast of South America. 



Material examined. — Bahamas; Charles L. Edwards; specimens 

 returned to sender.
