boscis curved downward, tapering to a blunt, rounded point, cylindri- 

 cal at the base. The chelif ores and palpi arise from a rim around the 

 base of the proboscis. 



Chelifore: 2-jointed, the scape armed with a thick-set group of 

 thornlike processes on the dorsal distal half. Chela slightly larger 

 than scape, fingers bowed, without teeth, tips overlapping. There 

 is a sharp process on the outer margin of the palm over the insertion 

 of the dactylus. 



Palpus: 7-jointed, first and third short, subequal, second and 

 fourth long, second about three-fourths as long as the fourth. Three 

 terminal joints short, fifth and seventh subequal, sixth slightly longer. 

 The palpus originates directly below the chelifore. 



Ovigers: Absent. 



Third leg rather stout, first and tliird coxae subequal, second slightly 

 longer. There are several spurs on the first, and one or two on the 

 second coxa. Femur plain, slightly curved, subequal to first tibia. 

 Second tibia longer than first. Tibiae armed dorsally with sharp 

 spurlike processes ; and bearing short spines along the ventral surfaces. 

 Tarsus short, cuplike, with a large spine dorsally and a larger one 

 ventrally accompanied by several small spines. Propodus slightly 

 arched, sole armed with one very large spine proximally and two
