The dorsal face of the second abdominal segment consists of a single plate, 
undivided by longitudinal sutures, with a deep depression on each side of the 
middle. The following segments are unsymmetrical on the two sides of the 
unique type specimen (female), the abdomen being twisted to the right. The 
lateral margins of these segments are laciniated. 
Eyestalks spinulose above; eyes very black, with downward aspect. Distal 
segment of antennule much longer than the antecedent segment, tuberculous 
above. Antenne of moderate length; outer margin of first segment spinulose ; 
second segment spinulose, and produced on the outer side to a long spine; 
movable acicle reaching to the distal end of the peduncle, spinose, the longer 
spines marginal, one spinule on the lower side and another on the upper side 
near the base; penultimate and ultimate segments of peduncle bear small 
setiferous tubercles. Right cheliped more robust than its fellow, thickly beset 
with strong spines. Ambulatory legs long, robust, spinose like the chelipeds; 
their basal segments are wellnigh covered by the overlapping margin of the 
abdomen (in the female). 
Length of carapace, 113 mm.; length of rostrum, 9 mm.; breadth of caras 
pace, 113 mm.; length of posterior ambulatory legs, 255 mm.; merus, 68 mm.; 
carpus, 39 mm.; propodus, 72 mm.; dactylus, 56.5 mm. 
Station 3353. 695 fathoms. 1 female. 
This species, like the one next described, is much longer legged than P. gran- 
ulosa (Jacquinot), the type of the genus. In this regard it is more like the two 
“Challenger” species described by Henderson. The specimen above described 
was infested with a huge Peltogaster 36 mm. in breadth. 
Paralomis longipes, sp. nov. 
Male. — Carapace triangular; gastric, cardiac, and branchial regions well 
defined, protuberant; the most prominent part of the cardiac area reaches a 
higher level than the branchial areas; whole surface of carapace thickly cov- 
ered with blunt papilla; viewed under a lens each tubercle is seen to be en- 
circled with a ring of short, stiff set» ; one of the tubercles, situate in front of 
the centre of the gastric region, assumes a spiny form. Rostrum furnished with 
three prominent spines, one median and inferior, two lateral and superior; the 
latter are not so long as the inferior spine; there is, too, a spinule on the 
lower side of the inferior spine, and a still smaller one above, between the roots 
of the superior pair. There are two pairs of long spines on the anterior margin 
of the carapace, one at the external orbital angles, the other at the antero-lateral 
angles of the carapace. There are also three or four prominent spines on the 
side of each branchial area. Eyestalks spinulose above. Basal segment of the 
antenna armed with an external spine, the second segment with severai spines, 
the most prominent of which is on the outer side; acicle furnished with five 
prongs or spines, the largest median, the others lateral; flagellum much longer 
than the carapace. Cheliped of moderate size (the right one has been lost from
