REPORT ON THE ANOMURA. 79 



length beyond the antennal peduncle, a few hairs are present on their upper surface ; the 

 ophthalmic scales are of small size and obscurely bidentate. The antennal acicle extends 

 to the middle of the last joint of the peduncle, its surface is pubescent, and it is armed 

 with two spines on the'outer border and one or two on the inner ; the external prolongation 

 of the second joint is short and its apex bidentate ; the flagellum is nearly as long as the 

 body and but slightly ciliated. 



The chelipedes are similar in appearance and subequal in size, with their terminal joints 

 slightly pubescent. The merus has a circular red patch of large size on both its inner 

 and outer surfaces towards the distal end, the external surface is also slightly tuberculate, 

 and the inner and distal margin inferiorly bears a few spinules ; the carpus is of small 

 size, not equalling the dactylus in length, its upper surface, which is somewhat narrow, is 

 covered with scattered spiniform tubercles ; the upper surface of the propodus is armed in 

 a similar way, many of the tubercles having corneous tips, and a specially prominent row 

 is found on the inner margin ; the fingers are more than half the total length of the pro- 

 podus, and armed in the same manner as the last joint, their opposed edges are provided 

 with small, regular, pearly teeth. The ambulatory limbs are moderately pubescent, and 

 the anterior borders of the carpal and propodal joints are slightly spiny ; the dactyli are 

 slightly more than one and a half times the length of the propodi, and both theii- surfaces 

 and margins are clothed with long stiff hairs, the terminal horny claws also are well 

 developed. The penultimate pair of legs are moderately pubescent, but the last pair are 

 almost smooth. The merus of the external maxillipedes possesses a few minute spinules 

 on the internal border. 



The penultimate abdominal segment is traversed by a deep transverse impression, 

 and a faint longitudinal groove is also present, the ultimate segment is four-lobed, two 

 of the lobes being produced. 



The above description is taken from an adult male which gives the following measure- 

 ments : — Length of body 43 mm., of carapace 16 mm., of chelipede 30 mm., of third right 

 leg 42 mm. , of ocular peduncle 1 mm. 



This species is distinguished by the remarkable development of the ocular peduncles. 



Habitat. — Station 122, off Pernambuco ; depth, 350 fathoms; bottom, red mud. 

 Two specimens (one of which is immature), in shells of Cassidaria (Sconsia) striata, Lam. 



Pagurisies hians, n. sp. (PI. VIIL fig. 4). 



Characters. — The anterior portion of the carapace is ovate, and slightly tuberculate 

 towards the margins and anterior border, the projections on the frontal margin are sub- 

 acute and but slightly prominent, the two lateral being more strongly marked than the 

 median ; the posterior portion is membranous and shows very slight traces of calcification 

 towards its centre.
