many as five spines. A sharp dark-tipped spine at the external orbital angle, 
another at the antero-lateral angle of the carapace, and four or five, irregu- 
larly arranged, on the margin of the branchial region. 
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 in the unique type specimen (female), the abdomen being twisted to 
the right. The lateral margins of these segments are laciniated. 
Eye-stalks spinulose above, eyes very black, with downward aspect. 
Distal segment of antennule munch longer than the antecedent segment, 
tuberculous above. Antennz 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 th upper side near the base; the penultimate and ultimate 
segments of the peduncle bear small setiferous tubercles. Right cheliped 
more robust than its fellow, thickly beset with strong spines. Ambulatory 
legs of moderate length for this genus, stout, spinose like the chelipeds; 
their basal segments are well-nigh covered by the overlapping margin of the 
abdomen (in the female). 
Length of carapace, 113 mm.; length of rostrum; 9 mm.; breadth of 
carapace, 115 mm.; length of posterior ambulatory legs, 255 mm. (merus, 
68 mm.; carpus, 39 mm.; propodite, 72 mm.; dactylus, 56.5 mm.).

Male. — Carapace triangular ; gastric, cardiac, and branchial regions well 
defined, protuberant; the most prominent part of the cardiac area attains to 
a higher level than the branchial areas ; whole surface of the carapace thickly 
covered with blunt tubercles ; viewed under a lens each tubercle is seen to 
be encircled with a ring of short stiff setae; one of the tubercles, situated in 
front of the centre of the gastric region, is spiniform. Rostrum furnished 
with three prominent spines, one median and inferior, two lateral and su-
