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 siDecies) it is 

 distinguished by the long setse, gastric spines, and broader carapace. From 

 the last it differs in being very hairy, etc. M. rosacea comes from the north 

 coast of Spain, M. 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 anterior border of the carapace is convex 

 between the eyes and the antennae, 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 pleurae of 

 the second segment tuberculate, all the pleurae rounded. The eye has a trans- 

 verse granulated tubercle running over tlie cornea from the inner side. The 

 antenna) 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 tliree 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. 



Length, 23 mm.; length of carapace, 12 mm." breadth, 8 mm.; length of 

 rostrum, 3 mm. 



Station 3404. 385 fathoms. 1 male. 



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
