Description.—Trunk rather heavy, lateral processes separated by 
slightly more than their own diameter. Dorsal trunk tubercles not 
quite so tall as eye tubercle, pointed. Tubercles on lateral processes 
very short. In addition to the dorsal trunk tubercles on the three 
anterior trunk segments there is a small one over the base of the 
abdomen. Eye tubercle cylindrical at base, bluntly conical at apex. 
Eyes large, slightly protuberant, at middle of tubercle. 
Proboscis pyriform, about three-fourths as long as trunk. 
Abdomen about as long as last trunk segment, cylindrical. 
Palpus 9-jointed. Second joint slightly curved, larger distally, 
longer than fourth. 
Chelifore: Scape 1-jointed, about as long as neck. Chela globular. 
Oviger heavy, 9-jointed. Third joint curved, without lateral 
tubercles, fourth joint about as long as third. Denticulate spines: 
11:8:6:12. The last spine is not markedly denticulate and appears 
to be opposed to the terminal claw. Leg short, thick, with a promi- 
nent lateral line on the anterior side, extending out to the propodus. 
Femur and tibiae subequal. Tarsus very short, not much longer than 
wide. Propodus slender, curved, with a row of fine spines on the sole. 
Terminal claw stout, blunt, about three times as long as width at base.
