REPORT ON THE A NOMURA. 69 



This species is allied to Eupagurus constans, Stimpson, and Eiqxujiirus itpinuUmanus, 

 Miers ; from the former it is distinguished by the absence of the spine on the inner 

 surface of the ischial joint of the right chelipede, the spines on the hand are scattered all 

 over the upper surface, and the setigerous tubercles are absent ; in the latter species the 

 eyes are slender, the antennal aciclc does not exceed the ocular peduncle, and the spinules 

 on the right hand are mostly arranged in two rows. Eujxtgiiriis armatus (Dana), is 

 an allied species, but the cornepe are not dilated, and the general form of the chelipedes 

 is different. 



Habitat. — Stations 204a, 204b, off Tablas Island; depth, 100 to 115 fathoms; 

 bottom, green mud. A female with ova, in a shell of Fusus nvphonicvs, E. A. Smith. 



Eupagunis ruhricatus, n. sp. (PI. VII. fig. 4). 



Characters. — The anterior portion of the carapace is smooth and moderately flat, 

 the frontal projections are scarcely indicated, the median being obtusely rounded ; the 

 posterior portion is entirely membranous. 



The ocular peduncles are moderately stout, with the corncEe dilated ; the ophthalmic 

 scales have the terminal portion slender and acuminate. The antennal peduncle slightly 

 exceeds the eye-stalks in length ; the acicle is long and slender, reaching nearly to the 

 end of the peduncle, its inner margin is pubescent and has a double curve ; the external 

 prolongation of the second joint is spinulous, and extends as far as the distal end of the 

 penultimate joint, a minute spinule is also present on the inner margin of the second 

 joint. The second joint of the antennular peduncle has its distal end not reaching the 

 termination of the eye-stalk. 



The chelipedes are unequal and of moderate size, the terminal joints are covered 

 with a matted pubescence, and the hands are swollen from side to side. The right 

 chelipede has the meral joint trigonal, its lower surface tuberculate, and its distal and 

 upper border with a single spine and a fringe of hairs ; the carpus is a little more than 

 half the total length of the propodus, with its breadth considerably less, the upper surface is 

 pubescent, and a number of conical spines are scattered over the inner half, those on the 

 free margin being specially prominent ; the propodus is much broader than the carpus, 

 its upper surface is covered with a matted pubescence, and jDossesses an irregular central 

 elevation ; scattered somewhat sparinglj^ here and there, but especially towards the centre 

 of this surface, are white rounded tubercles, the inner and outer margins are fringed with 

 long hairs, and bear in addition a row of somewhat blunted sjiines ; the upper surface of the 

 dactylus possesses several rows of rounded tubercles, and its inner margin is armed with 

 tubercular spines, the tip is folded under that of the immobile finger. The left chelipede 

 has the merus similar to that of the right chelipede, the upjoer surface of the carpus is tra- 

 versed by two rows of spines, with a smooth portion between ; the propodus is placed at an
