while the lateral parts of the carapace, the abdominal pleurx, and the append- 
ages are bright red. 
Length of a large female, 119 mm. ; carapace, 51 mm. ; rostrum, 14 mm. ; 
second antenna, 225 mm. 
Station 3418. 660 fathoms. 23 males, 32 fem. (2 ovig.). 
ADA O70. 2 males.

In some small specimens the granulations arranged in two longitudinal 
rows on the gastric region are transformed into small spines. In one young 
example the rostrum is armed with two spines on one side and with one on 
the other side. 
The prominent spine on the basal end of the telson at once separates 
this species from any hitherto described. The roundness of the cephalo- 
thorax resulting from the convexity of the branchiostegites is also character- 
istic. The abdominal pleure are intermediate in shape between those of 
NN. stewarti and N. agassizi. There is but one pair of spines (the anterior 
pair) behind the orbit, where there are two pairs in NW. agassizi and 
NV. atlantica. 
All the forms of Nephropsis hitherto described are very closely related 
to each other, and might be treated as geographical races of one widely 
distributed species. The distribution, so far as known, is as follows: NV. stew- 
arti W.-M., Bay of Bengal; WV. carpenteri W.-M., Bay of Bengal ; WN. agassizit 
A. M. Edw. (= W. aculeata Smith, and J. rosea Bate), West Indian region, off 
the Bermudas, and off the south coast of New lngland ; JV. atlantica Nor- 
man, Firje Channel and Arabian Sea; JV. suhmi Bate,* off Arru Island ; 
NV. occidentalis Fax., off Acapulco, Mexico.

* Rep. Challenger Macrura, p.181. This species is referred to by Bate on pp. 171, 175 of the same work, 
under the name of Nephropsis orientalis. Nephropsis cornubiensis Bate and Rowe (Rep. Brit. Assoc. Adv. 
Sci., 1880, p. 160) is not a Nephropsis at all (see Rep. Challenger Macrura, p. 177).
