outer angle of each lobe forming a distinct little lobule. Orbital 

 margin with two grooves above and one below outer angle. Eyes 

 on short thick stalks. Basal antenna! article large, extending out- 

 wards and upwards into the gap between front and orbit. Chelipeds 

 unequal, fingers large, deeply hollowed at tip. Merus, carpus and

Diagnosis. — Carapace areolated; lateral teeth sharp, separated by 

 concave spaces; front advanced, four-toothed. Fingers gaping, 

 spooned. Legs spinulous and hairy. 



Bescription. — Carapace evenly convex, areolated; lobules rather 

 prominent anteriorly and antero-laterally, with nearly smooth sur- 

 faces. No transverse ridges. Surface posteriorly glabrous. Antero- 

 lateral teeth four (excluding angle of orbit), subequal, small but 

 sharply prominent; interspaces broad, concave. Front advanced, 

 sublaminiform, median notch small, lobes oblique, outer lobules 

 produced. A blunt subhepatic tooth or tubercle just in front of the 

 first of the four antero-lateral teeth. 



Anterior margin of merus of maxillipeds oblique. Chelipeds stout, 

 not very unequal; merus spinulous above. Upper surface of carpus 

 and manus slightly rugose. Two teeth at inner angle of carpus, the 

 upper one much the longer. Chelae dissimilar; immovable finger 

 with color ending in an oblique line on palm, and with a tooth at 

 middle ,of prehensile margin, which may be absent in the minor chela 

 of old specimens. Major dactyl with a small tooth near its base. 

 Fingers spooned, gaping, the gape mder in the minor chela. Legs 

 spinulous and hairJ^

 spotted with red. 



Measurements. — Male (13833), length of carapace 17, width of same 

 23.5, fronto-orbital width 13.6, frontal width 6.1 mm.
