188 BULLETIN OF THE 
at anterior boundary of hepatic area; a deep depression back of each hepatic 
area and another across the anterior part of the cardiac region; the wpper surface 
of the carapace is adorned with spinulose tubercles, and a median longitudinal 
row of more prominent spines runs along the gastric and cardiac regions; the 
anterior spine of the cardiac region overhangs the transverse depression, the 
posterior spine of the row springs from the hinder rim of the carapace. There 
is a median hooked spine on the tergum of the second, third, fourth, and fifth 
abdominal segments and many spiny tubercles irregularly disposed on these 
segments ; the pleurz of the third to the sixth abdominal segments are narrow 
but blunt, those of the second to the fifth are costate. The ocular peduncle is 
movable and devoid of a spine. The antenne are about as long as the body ; 
the basal joint has an inferior and a small external spine ; the second joint also 
bears an external spine. The chelipeds are long and slender ; all the joints from 
the ischium to the propodus are equipped with longitudinal rows of small 
spines ; the chela is not broader than the basal part of the propodus, the fingers 
are straight, their prehensile edges denticulate. The ambulatory appendages 
are spinulose. 
Length of male, 49 mm.; length of carapace, 25 mm.; breadth of carapace,

This species is subject to considerable variation. In the specimens from 
Stations 3402, 3403, and 3406 the tubercles of the carapace are more numerous 
and less spiny than in those secured at the other stations. The ambulatory 
appendages of all the “ Albatross” examples are apparently more spiny than 
in the types from the ‘‘ Challenger.” The latter came from the Straits of 
Magellan, 245 fathoms. 
Munidopsis quadrata, sp. nov. 
Carapace quadrangular, the anterior and lateral margins forming a right an- 
gle; upper surface flat, spineless, but furnished with low squamiform tubercles,
