Palpus slender, longer than proboscis. Second segment longest, 
longer than third and fourth segments, which are subequal. Last 
segment slightly shorter than fourth. 
Chelifore: Scape about one-fifth longer than proboscis. Chelae 
about as long as scape, palm slender, subequal to fingers. Fingers 
curved, each with about 15 spinules. 
Oviger: Fourth and fifth segments about equal, nearly straight and 
slightly swollen distally. Terminal spine as long as tenth segment, 
with 12 short, evenly spaced teeth on its distal three-fourths. Den- 
ticulate spines rather broad, with about three large broad denticula- 
tions. Spine formula: 17:12:9:9. 
Leg slender, armed with scattered setae, some of them about three 
times as long as the diameter of the leg segments. Tarsus and pro- 
podus subequal. Auxiliary claws at least half as long as terminal 
claw. The spines on the propodus are widely spaced and of even 
size.

Remarks.—-Except for the long setae on the legs and the absence of 
eyes, this species resembles N. macrum. The chela is smaller and the 
fingers are armed with comparatively few spinules. Both specimens 
are somewhat damaged.
