below the anterior margin of the carapace. The abdomen is devoid of spines, 
the pleure have truncated lateral angles. A spine projects over the cornea of 
the eye. The antennm are shorter than the body; a spine on the outer side 
of the basal joint, one on each side of the second joint, and one on each side 
and one on superior margin of third joint. The chelipeds are long, spinose, 
except the fingers ; hand lung, the basal part longer than the fingers. All the 
joints of the ambulatory appendages are spiny except the dactyli. 
Length (ovigerous female), 40 mm. ; length of carapace, 13.5 mm.; breadth,

Munidopsis tanneri, sp. nov. 
Carapace flat, quadrangular, covered with squamous setiferous tubercles 
which have a tendency to develop spiny points on the gastric region. This 
is especially true of a transverse row of six on the anterior part of that region. 
The rostrum is triangular and horizontal. There is a prominent spine on each 
side of the anterior margin of the carapace between the eye and the antenna, 
another at the antero-lateral angle, and two or three on the side of the hepatic 
area; the hind border,of the carapace is denticulated. A small spine over the 
eye. Antenne shorter than the body ; one spine on the outer side of the first 
‘joint, two lateral and one superior on the second and third joints. Cheliped 
(present in only one specimen) long, slender ; merus and carpus many-spined ; 
propodus spiny along the upper and lower margins ; tips of fingers enlarged 
and denticulated. Ambulatory limbs : a prominent row of spines on the upper 
edge of the merus and carpus, propodus and dactylus devoid of spines. Abdo- 
men without spines; pleura narrow, angles rounded. 
Length, 41 mm.; length of carapace, 23.5 mm.; breadth, 15.5 mm.; rostrum, 
6 mm. 
Station 3396. 259 fathoms. 2 males, 1 female (1 male with Bopyrus).

This species is nearly related to M. scabrosa, but differs from the latter spe- 
cies in having the carapace broader and flatter, with squamous tubercles which 
are not produced into points except a few on the gastric area, The spine be- 
tween the eye and the antenna is longer; the propodi of the ambulatory legs 
are smoother, with no well-developed spines. 
Munidopsis hamata, sp. nov. 
Body and limbs clothed with short, scattered sete. Rostrum long, curved. 
slightly upward, basal half furrowed longitudinally, with a row of short spines 
on each side of the furrow ; infero-lateral edges of rostrum also furnished with 
small spines. Carapace quadrangular, anterior border forming a right angle 
with lateral border, both borders spinulose ; lateral border with an indentation
