of inner edges lined with small <,'ranules, the inner sides slightly 

 hairy; niol)ile finsjjor snioutli iiitornally ; upper l)or(ler with about 

 fourteen rather high, obtuse granules and a few seta;. 



Right chelipede about G mm. long ; nierus joint similar to that 

 of the left; carpus with five strong spinules on the upper border; 

 hand very short, the pahu has four closely placed spinules on its 

 upper border; the lower border and the inner surface rounded, 

 with a few scales and some short sette; external surface and fingers 

 clothed with long hairs; fingers acute, corneous at the tips and 

 slightly setose. 



Ambulatory legs of the right side unequal, the first 8-5 mm. in 

 length, the second 10 ram.; ischium joint of the first leg wider 

 than long, fringed with hairs on the upper and lower distal 

 borders ; merus joint more than twice as long as deep; the upper 

 border bears about fourteen curved spinules ; propodus equal to 

 the merus in length, subcylindrical, but laterally sulcated distally; 

 upper border with twelve spinules, slightly larger than those on 

 the preceding joint and inclined forwards. 



Tarsus stout, slightly curved, compressed and grooved at the 

 sides to within a short distance of the horny claw. The second 

 leg differs from the first in having the tarsus and ischium joints 

 longer; the latter is not quite twice as long as deep. The spinules 

 are also smaller in size and number. 



Ambulatory legs of the left side equal in length (8-5 mm.), the 

 first similar to its fellow on the right side. The propodal joint of 

 the second has a deep longitudinal sulcus on the external surface; 

 it is bounded below by a prominent crest, which bears about 

 sixteen subspiniform granules ; the lower border is armed with 

 ten or twelve spinules. 



Tarsus sulcate and feebly carinate externally ; there are a few 

 spinules on the outer angle of the upper border and many on the 

 lower, disposed in two rows ; the inner row is continuous, the 

 outer terminates at the distal third. 



Fourth pair of legs stout ; the rasp is elongate and sub- 

 triangular in shape, with about five scales in a row at its broadest 

 point. 



Fifth pair of legs slender, fold or bent upwards over the hinder 

 margin of the carapace. 



First pair of abdominal appendages short, stout, slightly curved 

 and bilobateon the inner aspect of their apices; the outer arcuate 

 distal edges are armed with linear rasps, composed of numerous 

 small curved spinules ; there is a tuft of simple setse on the inner 

 side of the base of each appendage, and numerous simple hairs 

 on the margins of the apical lobes.
