Diagnosis. — Size small. Prominent raised lines of granules on 

 dorsum. Edge of front thick, grooved. Lateral teeth prominent, 

 third and fourth curved forward. Color of immovable finger con- 

 tinued a little way on palm. Lateral extremities of third abdominal 

 segment of male rounded. 



Description. — A small species. Carapace distinctly areolated, the 

 regions separately convex and ornamented with raised lines of gran- 

 ules. The principal ones are: A transversely oblique hepatic ridge 

 which forms with a transverse protogastric ridge a regular though 

 broken arch across the carapace; a second protogastric ridge behind 



the first, and subparallel to it, but the 

 hinder one is slightly oblique, so that they 

 are farther apart at outer than inner end; 

 a short epigastric ridge; either side of 

 metagastric region at its greatest width 

 a ridge almost transverse but slanting a 

 little backward from median line; a little

 6. Abdomen. After Benedict and branchial ridge; a short mesobranchial 



ridge, and a similar metabranchial ridge in 

 front of the end of the posterior margin of the carapace. Front with 

 a median V sinus, each lobes inuous and forming a rectangular outer 

 comer; edge thick, obhque and guttered. Inner margin of orbit 

 high; superior sinuses V-shaped, enclosing a lobe; outer emargination 

 deep, inner angle a conical, acute tooth. First lateral tooth (the 

 orbital) small, rectangular; second larger, lobiform; next three 

 teeth projecting prominently outward, tips curved forward, well 

 separated, third and fourth with arcuate outer, and slightly concave 

 anterior margin, the third the larger; fifth narrow, directed nearly 

 outward; fourth and fifth prominently ridged. 



Chelipeds of male very unequal; carpus rugose or tuberculate with 

 a deep distal groove; manus gently rugose above, with a shallow 

 groove along the margin; in small specimens the roughness or granu-
