REPORT ON THE ANOMURA. 71 



Tlie anteunular peduncle exceeds the eye-stalk by nearly the whole length of the last 

 joint, which also extends considerably farther than the end of the antennal peduncle. 



The chelipedes are very unequal- and almost devoid of spines, the right with a broad 

 and flattened hand. The right chelipede has the merus with its outer surface rugose, 

 the lower surface convex and granular, a few spiuiform tubercles are present on the lower 

 and outer edge ; the carpus is more than half the total length of the propodus, its upper 

 surface is coarsely granular, and the lateral borders are raised and slightly spinose, the 

 lower surface is somewhat angular and covered with small tubercles ; the propodus is 

 much broader than the carpus though its vertical dimension is considerably less, the 

 upper surface is polished, slightly convex from side to side, and everywhere finely 

 granular, the lateral borders are convex and remarkably thin, the lower surface is also 

 finely granular ; the free edge of the dactylus is very thin and the upper surface is 

 finely granular. The left chelipede is of small size and extremely narrow, the lower 

 surface of the merus is slightly spinose, and the carpus possesses a median row of spinules, 

 its inner border also is somewhat tubercular ; the propodus is a little wider than the 

 carpus, a short tubercular carina exists on its proximal half, and the outer border is thin, 

 the fingers are slightly bent downwards, and are more than half the total length of 

 the hand. The ambulatory limbs are subequal in length to the right chelipede, and 

 comparatively smooth, a few spinules exist on the anterior border of the carpal joints of 

 the first pair ; the dactyli are longer than the propodi, moderately curved, with a few 

 setae on the outer border towards the apex. 



The terminal portion of the abdomen is wanting in the single specimen. 



Length of body 16 mm., of right chelipede 22 mm., of left chelipede 15 mm., of 

 third left leg 22 mm., of ocular peduncle 3 mm. 



The form of the right chelipede — the broad flattened hand of which probably serves to 

 plug up the mouth of a shell — is characteristic of this species ; in this respect it l)ears some 

 resemblance to " Pagurus severus," A. Milne-Edwards, from the " Talisman " dredgings. 



Habitat.— 8ta,tioii 122, ofi" Pernambuco ; depth, 350 fathoms; bottom, red mud. A 

 male specimen, in a shell of Pleurotoma sp. 



A Pagurid without chelipedes from Station 201, ofi' Samboangan, Philippines, appears 

 to belong to the genus Eupagurus. It occurred in the shell of a species of Trochus. 



Genus Spirojjagurus, Stimpson. 



Spiropagurus, Stimpson, Proc. Acad. Nat. Sci. Philad., p. 74, 1858. 



Anterior portion of the carapace depressed, the cervical groove deep ; front with the 

 rostral jjrojection but slightly marked. Ocular peduncles short and stout, with the 

 cornese dilated ; the basal scales of moderate size and separated by a considerable
