Diagnosis. — Cardiac lobe flat, granulous, walls of trench with raised 

 rim. Branchial region granulous, a few of the granules enlarged- 



Description of female. — Carapace covered with large granules or 

 tubercles between which are fine punctae, in which minute hairs are 

 inserted; some granules are enlarged, namely, 1 on anterior part of 

 cardiac lobe, 4 on each branchial region and 1 intestinal. Rostral 

 horns small, a little flattened, without granulation but with some 

 hooked hairs. Preorbital spines more divergent than rostral spines^ 

 short, scarcely reaching the line of bifurcation of the rostrum. Upper 

 orbital border with 2 teeth, one superior, the other lateral. Basal 

 article of antennae armed with 3 spines; the largest forms its, anterior 

 outer angle, another its posterior outer angle, and the third, which 

 is smaller, is placed between the two; second and third articles cylin- 

 drical, flagellum small, surpassing by half its length the end of 

 rostrum. Regions of carapace very distinct. Epigastric lobes 

 separated from rest of carapace by a transverse sulcus which unites 

 the two fissures of the orbits; a slightly prominent, lateral, hepatic 

 spine; some other similar but smaller seines border the branchial 

 regions. Cardiac lobe flat, granulous and bounded posteriorly and 

 laterally by a deep trench-like depression with steep, smooth walls, 

 the margins of which are marked by a nongranulate crest; trench 

 absent anteriorly where the gastiic region borders the cardiac. 

 Chelipeds scarcely longer than the legs of first pair; hand smooth, 

 fingers sharp; wrist and arm with some pointed tubercles. Legs 

 smooth. Sternal plastron oval and very narrow. (A. Milne 

 Edwards, amended.) 



Measurements. — Female, holotype, length of carapace 23, width of 

 same 15 mm. 



Range. — Known only from the type-specimen. 



Material examined. — Near Barbados; 100 fathoms; December, 

 1871; Hassler Exped.; 1 female, holotype (Cat. No. 1937, M. C. Z.).
