GAMMARIDiE. 
the male with a short stout spine, in the female sub- 
apically with a fine hair. The eyes are very small, 
irregularly defined in form, and, in the living animal, of 
a bright lemon colour, showing very brilliantly in certain 
positions. The two pairs of hands are similarly shaped, 
somewhat resembling a pear, but the second pair are 
slightly larger than the first : they have the superior mar- 
gin almost straight; the palm is very oblique and slightly 
waved, marginate,* and fringed with a row of numerous 
equidistant short cilia, and a few solitary hairs ; defined 
by— two in the first, and one in the second — strong move- 
able spines, the posterior margin is very convex, and pro- 
duced posteriorly to the carpal articulation, it is fringed 
with four fasciculi of anteriorly curved hairs, and is 
capable of being compressed into a deep excavation on 
the anterior margin of the wrist ; the finger is long, 
curved, marginate upon the inner surface, and furnished 
with a distinct nail, the point of connection with the 
finger being defined by a sharp tooth. The posterior 
walking legs, instead of having the anterior margin 
furnished with spines, have small fasciculi of hairs. The 
elongated branch of the last of the caudal appendages 
is not so much developed as in N. aquilex . In other 
respects this animal bears a close resemblance to that 
species. 
This species was first taken by the Rev. A. R. Hogan, 
at Ringwood in Hants, in a pump-well sunk about 
fourteen years since, but there existed another well of 
much older date, at the distance of a few feet, that had 
been long closed up. It was also taken by Mr. Herbert 
Mullins (who has kindly presented specimens to us and

margin that frequently varies in appearance, and resembles a thin cutting
