notch from each inner supraorbital flange, latter a little convex. 

 Emargination of orbit as viewed above deepest or most posterior 

 in median portion of its extent, and outer corner with very slight 

 notch. Outer orbital tooth coalesced with first anterior lateral 

 tooth, only separated by slight emargination, also a little more 

 triangular, narrower and slightly more advanced than latter. 

 Second anterior lateral tooth broad, lobate, but little posterior 

 to first, though separated by deep notch. Third anterior lateral 

 tooth arcuate, narrower than second, separated from fourth by 

 very deep excavated notch, and apex deflected but little from 

 vertical. Fourth antero-lateral teeth triangular, directed 

 oblicpiely forward, pointed or more dentiform. Anterior-lateral 

 edges, along edges of teeth, with beading of fine granules. 



Orbits rather oblong, with inner tubercle and broader outer 

 flange comprising inferior edge, and these seen as viewed from 

 above. Eye rounded, with constricted pedicel, and base a little 

 more swollen than bulk of eye. Antennules robust. Antennae 

 slender. Maxillipeds large, cover branchial cavern, ischium width 

 about three-fourths its length, length of merus about three-fourths 

 its own width, and small terminal joints subequal. Subbranchial 

 regions all granular. Chelipeds large, massive, subequal. Pro- 

 podus swollen and smooth over surfaces, rather long, not greatly 

 elevated at dactylus articulation, but conic and slender pollex 

 bent down somewhat and curved a little inward at tip. Latter 

 also with external longitudinal groove and well-toothed along a 

 nearly straight cutting-edge, median denticles a little enlarged. 

 Dactylus similar to pollex, usually elongate, slender, conic, slight 

 tubercle basally and externally below, mostly with smaller and 

 less developed teeth than on pollex, and cutting-edge nearly ap- 

 proximated with latter. Carpus smooth above, convex, and 

 with large inner anterior tooth. Merus and carpus about equal 

 in length. Ambulatory feet similar, dactyls similar, pointed. 

 Male with slender post-abdomen, outermost of three fused seg- 

 ments with straight edges and similar to penultimate. Terminal 

 segment rounded. 



Color of carapace bright purple-blue. Carpus and hand bluish, 

 and color of fingers not continued on palm. Proximal upper half
