164 BULLETIN OF THE 
Echinocerus diomedee, sp. nov. 
Carapace subpentagonal, gastric and branchial regions inflated, the whole 
surface beset with tubercles which give rise to minute sete. There is one 
rather more prominent tubercle in the depression on each side of the gastric 
area. Rostrum short, three-spined; one of the spines is median and inferior, 
two are paired near the base above; in one of the two specimens obtained the me- 
dian spine is toothed below. The antero-lateral margin of the carapace is irregu- 
larly toothed. Eyestalks spinulose above, with one prominent spine projecting 
forward over the cornea. The movable scale or spine of the antenna is spinu- 
lose on each side (four or five spines on each margin). The merus of the cheliped 
bears a spine on the inner side at the distal end; the carpus is smooth outside, 
the inner border expanded into a seven-toothed crest setose within, the outer 
border straight, naked, and keeled; the chelz are of unequal size (the right 
being the larger), setose, spiny on the upper edge; fingers spoon-shaped within, 
setose and somewhat gaping. Ambulatory appendages: the meri are spinose 
on their edges; the anterior border of the carpus of the first pair is furnished 
with a crest whose edge is even and entire; the propodus of the first pair is 
crested along the proximal half of its anterior border, while the distal half is 
armed with two or three teeth; the carpus and propodus of the second and 
third pairs are toothed on the anterior margin, the propodus of the third pair is 
also toothed on the posterior margin; all the segments are hirsute, especially 
the dactyli. When the legs are closely folded against the sides of the carapace 
a wide interval is left between the carpi of the cheliped and first pair of am- 
bulatory appendages, bounded by the opposite crests of these segments, and 
forming a passage for the admission of water to the gills. This orifice is simi- 
lar to that seen in E. foraminatus Stimps., but it is not so perfectly formed 
The apex of the abdomen (in the female) is turned to the right (most strongly 
in the larger specimen); the marginal plates are wanting on the left side; all 
the abdominal appendages excepting the first are aborted on the right side. 
Length, 64 mm.; breadth, 71 mm. 
Station 3384. 458 fathoms. 1 female. 
Station 3394. 511 fathoms. 1 female ovig. 
In this species the acicle of the antenna is spinous on the margins only, as 
in E. foraminatus Stimps. 
Paralomis aspera, sp. nov. 
Carapace pentagonal, as broad as Jong; gastric, cardiac, and branchial regions 
well defined and prominent; whole surface of carapace and abdomen thickly 
beset with papillz or tubercles, each one of which is encircled with a crown 
of stiff setae. Rostrum short, indistinctly tripartite, multispinose. A sharp 
dark-tipped spine at the external orbital angle, another at the antero-lateral 
angle of the carapace, and four or five, irregularly arranged, on the margin of 
the branchial region.
