Diagnosis.— Three large tubercles on either side of ventral surface 

 of carapace. Four stout spines on anterior margin. Chelae covered 

 with small pointed tubercles. 



Description. — Carapace in the old pubescent above, margin densely- 

 hairy and armed anteriorly with four large curved spines with sharp 

 tips pointing obliquely downward; they are followed by a few small 

 spines, all well spaced. Front between the two submedian spines 

 subtruncate or sometimes sloping slightly backward toward the short 

 narrow fissure on the median line. Lower surface tuberculate and 

 along the margin finely granulate. An uneven transverse ridge 

 directly in front of the hollow in which the cheliped fits; farther for- 

 ward three large unequal granulated tubercles forming a triangle. 

 Antennary fossae limited in front by a pair of strong, oblique ridges, 

 which arise between two of the spines of the anterior border and meet 

 each other in the middle at the front of the epistome. Posterior 

 border of epistome raised into a prominent ridge, which is continued 

 across the front and some distance along the sides of the buccal area. 

 Peduncular articles of antennae tuberculate; the basal one has a 

 strong, inwardly directed tooth, and the terminal one a tooth on each 

 side of the base of the flagellum. A large swelling on outer side of 

 orbit and a small one above and below. The carpus of the cheliped 

 bears several denticulated tubercles, two of which are on the outer 

 margin; the manus is covered with tubercles more or less pointed. 



Color. — Coral sand above, with whitish gray hairs. Ground color 

 beneath, vinaceous-rufous. Rounded bosses on legs and subfrontal 

 region in ventral view vinaceous-cinnamon. Eyes black or bay. 

 Eggs Chinese orange. (W. L. Schmitt.) 



Measurements. — Male (66796), length of carapace 23.2, width 22.4 

 mm. 



Range. — North Carohna to the West Indies; dji to 49 fathoms.
