144 STALK-EYED CRUSTACEA. 
terior gastric region are not prolonged into spines, and the eye lacks any 
dark pigment. The absence of pigment in the eye, however, I think may 
be due to the action of alcohol. The spine at the antero-lateral angle of the 
carapace is bent down at a greater angle with the axis of the body than it 
is in the “ Albatross” species, and I think this is also true of the typical 
G. nobilis. 
Bate’s G. acuminata appears to be very closely allied to G. nobilis, and per- 
haps will prove to be only a smooth form of the latter species. 
G. giles. Wood-Mason is a smoother form characterized by the full 
development of the anterior part of the third crest of the carapace. In 
7. unguiculata Wood-Mason, the carapace and abdomen are covered with a 
velvety pubescence, the postero-inferior corners of the second and third 
pairs of abdominal pleure are angular rather than spinose, and the outer 
margins of the dactyli of the fourth and fifth pairs of legs are produced near 
the apex into a minute, incurved claw. 
The type specimen of @. nobilis was taken in 1131 fathoms near the Island 
of Dominica, W. I.

Rostrum equal in length to the rest of the carapace, armed with a pair 
of short, blunt lateral teeth a little in advance of the front of the eyes, and 
another pair of obsolescent ones at the root. Between these two pairs of 
teeth the margins of the rostrum are concave and a little raised. From the 
anterior teeth the rostrum tapers regularly to the point. The upper surface 
is plane and smooth (neither corrugated nor ciliated). A slight median 
carina, most obvious near the tip, runs the whole length of the rostrum 
from the anterior boundary of the gastrie area to the tip, and the lateral 
margins are lightly rimmed. The lower surface is grooved longitudinally, 
and wholly devoid of a median keel. 
The orbital spine is rather short and thick, and is directed a little out- 
ward and upward. The spine at the antero-external angle of the carapace 
is also short and thick, but slightly exceeding the orbital spine; it is turned 
but very slightly outward, but its downward deflection is stronger. From 
its base a low carina extends backward over the hepatic area. This carina
