186 BULLETIN OF THE 
spines on the meri of the ambulatory legs, and its greater pilosity. From the 
second (judging from Milne Edwards’s short description of that species) it is 
distinguished by the long sets, gastric spines, and broader carapace. From 
the last it differs in being very hairy, etc. M. rosacea comes from the north 
coast of Spain, MW. latifrons from the Barbadoes, M. tridens from St. Kitts. 
Munidopsis ornata, sp. nov. 
Carapace convex, the whole upper surface, including the rostrum, thickly 
covered with low squamous tubercles ; seen under a magnifying power the 
surface of each tubercle is seen to be made up of a number of secondary scale- 
like prominences; the tubercles are not lengthened out transversely to form 
ridges on any part of the surface; two of the tubercles on the gastric region 
take on a spiny character. The rostrum is nearly horizontal, triangular in 
cross-section, the margins serrate; the auterior border of the carapace is convex 
between the eyes and the antenne, but has no spine at this point ; lateral bor- 
der four-toothed, one of the teeth lying at the antero-lateral angle, two on the 
hepatic region, and one on the edge of the branchial region behind the cervical 
suture ; the posterior border is delicately festooned, but not armed with spines. 
The abdomen is spineless, its surface punctate, anterior half of the pleure of 
the second segment tuberculate, all the pleure rounded. The eye has a trans- 
verse granulated tubercle running over the cornea from the inner side. The 
antenne are very slender, and do not exceed the carapace in length. The 
chelipeds are moderately robust ; the merus tuberculate and armed with a row 
of short spines along the upper edge; the carpus spino-tuberculate, with two 
longitudinal furrows on the outer side; the hand almost smooth on the inner 
side, outer side and superior surface roughened with low tubercles ; fingers a 
little curved upward, spoon-shaped at the denticulate and setose tips. Ambu- 
latory appendages: meri flattened, tuberculate, upper edge produced to a spi- 
nose carina; the carpi have three denticulate ridges; propodi scabrous, with 
an irregular row of spines on under side; the dactyli have black tips, and are 
finely spinulose on their posterior edges.

Munidopsis scabra, sp. nov. 
The rostrum is triangular, slightly curved upward, carinated above, the 
lateral edges and the carina lightly denticulated. The carapace is covered 
with squamous setiferous tubercles which end in spiny points. There is a 
transverse row of six more prominent spiny tubercles on the gastric region. 
The posterior border of the carapace is ornamented with a denticulated rim 
(about eight denticles). There is a spine between the eye and the antenna
