without spines, except a few very minute dentiform ones along the inner 
edge of the propodus; the propodal digit is longitudinal and tapers to 
a slender incurved tip; the dactylus is a little longer and stouter than 
the propodal digit, and has a longer and more strongly curved tip, which 
closes beneath the tip of the propodus; the prehensile edges of both 
digits are sharp and minutely crenulate. The upper surface and the 
inner edge of the carpus and the upper surface and both edges of the 
chela are thickly clothed with very long and soft pubescence, directed 
distally. The succeeding pairs of legs are very nearly as in N. Stewart. 
The second pair are about three-fourths as long as the chelipeds, slender 
and perfectly chelate. The third pair are a little longer than the second 
and not quite as perfectly chelate. The fourth are a little longer than, 
and the fifth about as long as, the chelipeds. 
Very impertect female specimens, considerably larger than the males 
above described, have the chelipeds a little larger and stouter propor- 
tionally than in the males, and the pleura of the second to the fifth 
somite of the abdomen very slightly less prolonged, but still acuminate 
and spiniform, and very different from NV. Stewart. 
One of the males and an imperfect female give the following:
