REPORT ON THE ANOMURA. 131 



somewhat bent. The strife on the surface of the carapace are numerous and pul)oscent ; 

 the gastric area is moderately convex, with two spines in front placed immediately behind 

 the supraorbitals ; the cardiac area is unarmed and almost flat ; three spines placed in 

 a longitudinal row are present on the boundary between each branchial region and the 

 cardiac area. The lateral margin of the carapace bears five or six spines, but with the 

 exception of the first none are of large size ; the posterior margin is unarmed. 



The clielipedes are wanting in the single specimen. The ambulatory limbs are 

 flattened ; the upper surface of the merus, carpus, and propodus is covered with hair-clad 

 scales of small size, and the lateral margins of the two former joints are spinose ; the 

 dactyli are more than half the length of the propodi. 



The eyes are of large size and strongly compressed, with a fringe of long hairs passing 

 over the upper surface of each cornea. The anterior prolongation of the first antennal 

 peduncular joint is long, slightly curved, and freely movable, forming a spine visible from 

 above which lies external to the eyes. The ischium and merus of the external maxilli- 

 pedes are finely squamose externally, the former has a short conical spine at the distal 

 end of its inner border, while the latter has a single well-marked spine near the middle 

 of the same border, and a spine of smaller size at the distal end of the outer border. 



The second, third, and fourth abdominal segments are armed precisely as in the last 

 species ; the dorsal surface of the fifth and sixth segments, telson, and last 2>air of 

 appendages is covered with minute ciliated scales. 



Breadth of carapace (of a female) 17 mm., length of body 39 mm., of carapace 

 16 mm., of rostrum 8 mm., of first ambulatory leg 46 mm. 



This species, inadvertently omitted from the diagnoses of the new species of 

 Galathodea taken by the Challenger, is allied to Munida normani, from which, however, 

 it is distinguished by its longer rostrum, the difi'erent form of the cardiac area of the 

 carapace, the smaller and pubescent scales on the ambulatory limbs and last abdominal 

 segments, but above all by the great development of the antennal spine. 



Habitat. — Station 200, off" Sibago Island, Philippines ; depth, 250 fathoms ; bottom, 

 green mud. An imperfect female specimen.

Cliaracters. — The rostrum is almost horizontal and a little more than one-third the 

 length of the carapace ; the supraorbital spines are slightly curved and about three-fourths 

 the length of the rostrum. The strise on the surface of the carapace are finely granulated 

 and slightly pubescent ; the gastric area is convex, with a pair of spines placed 

 immediately behind the supraorbitals ; the cardiac area is distinctly circumscribed, and 

 triangular in outline, with a well-developed median spine on the anterior margin which
