REPORT ON THE ANOMUEA. 99 



Paguropsis typicits, n. sp. (PI. X. fig. 4). 



Characters. ^The anterior portion of the carapace is smooth, strongly convex from 

 side to side, and firmly calcified ; the rostral j^rojection is compressed lateral!}^ and 

 carinated superiorly, with its apex which is acvite and slightly deflexed extending beyond 

 the ti^is of the ophthalmic scales, a slight swelling is seen on the carapace on either side 

 of the base of the rostrum, and the lateral frontal projections are but slightly marked ; on 

 the posterior portion the cardiac area is calcified, as is also though to a lesser extent the 

 antero-internal margin of the branchial area. 



The ocular peduncles are short, with the cornese deeply pigmented, strongly dilated, 

 and semi-lunar in outline when viewed from above ; the ophthalmic scales are of small 

 size, and each terminates in an acute spinule. The antenna! peduncle scarcely exceeds 

 the eye-stalk in length ; the acicle is poorly developed and but slightly curved, not 

 reaching the middle of the last joint of the peduncle ; the external prolongation of 

 the second joint is almost obsolete. The antennular peduncle exceeds the eye-stalk liy 

 the length of its terminal joint ; the upper of the two flagella is strongly developed, and 

 densely ciliated. 



The chelipedes are of similar conformation and almost equal size (in the single male 

 specimen the left is somewhat larger, a condition possibly due to accident), while the 

 terminal joints are thickly clad with bristle-like hairs. The lower aud inner margin of 

 each ischial joint bears a few tubercular spinules ; the merus is twice the length of the 

 carpus and distinctly trigonal in shape, the upper margin is tuberculate and slightly 

 rounded, the two lower margins are pubescent, and armed with blunt spinules, the 

 surfaces are comparatively smooth, and the anterior margin is slightly raised on the 

 superior surface ; the carpus is about half the length of the jiropodus, and its surface is 

 remarkably deficient below, so that the hand can be folded till it comes in contact with 

 the proximal half of the limb, the upper surface is slightly oblique, and armed with 

 numerous long setse, most of which arise from tubercles ; the upper surface of the pro- 

 podus also shows a slight amount of obliquity, the lateral borders are rounded (especially 

 the outer), and the marginal setse are of considerable length, the setse on the upjjer 

 surface arise from tubercles which show a tendency towards arrangement in rows, and 

 nvimerous tufts of setse are present on the lower surface ; the fingers are slightly more 

 than half the total length of the hand aud but slightly curved, the dactylus bears a few 

 small teeth on its inner proximal margin, and the corresponding margin of the immobile 

 finger is finely crenated, the lower surface is slightly excavated towards the apices, which 

 are tipped by small horny processes, the setse are chiefly seen on the upper and outer 

 surfaces and are mostly arranged in tufts. The ambulatory limbs are of moderate length, 

 with the meral, carpal, and propodal joints smooth and flattened, a few marginal hairs 

 alone being present ; the dactyli of the second pair are twice the length of the propodi
