RATHBUN— MARINE BRACHYURA 233 



Chelipeds not very unequal ; inner angle of wrist spinulous ; palm granulous on outer 

 surface, granules concealed beneath long hair. Fingers brown, not gaping, toothed along 

 prehensile edges, immovable fingers as long as wide. 



This species, in the smoothness of its carapace, resembles A. nudus A. Milne Edwards 

 (Conf. de Man, Journ. Linn. Soc. London, Zool., xxii. 1887, p. 49, pi. 2, figs. 2, 3), but the 

 latter is much broader, with strong antero-lateral teeth and smooth palms.

Amirante, 25—30 fms., Sta. Ell; 1 ? ovig. C. 1. 6'8 mm., C. b. 9"3 mm. 



Carapace very convex in all directions ; scarcely any indication of regions ; covered 

 with a short, fine, light-coloured pubescence. Antero-lateral margin with three conical 

 teeth, each tipped with a slender spine ; the first of these teeth has a secondary spine on 

 its posterior slope ; besides there is a small spine at the outer angle of the orbit. Front 

 composed of two oblique lobes, separated by a broad emargination, and without a distinct 

 tooth at the outer end. Two faint notches in upper margin of orbit, and a broad sinus 

 beneath the outer angle ; margin granulate ; inner angle armed with a spinule. 



The chelipeds and legs have many longer hairs mixed with the short tomentum. 

 Chelipeds unequal ; arms with two sharp teeth above ; wrists and palms granulate ; 

 lower distal half of larger palm smooth and bare ; a few granules near the palmar end 

 of the dactyls ; fingers of large claw very broad and smooth ; those of small claw narrower 

 and with one or two grooves ; prehensile edges with low irregular teeth which leave no 

 gape ; tips acute, crossing ; colour of fingers (in alcohol) light pinkish, this colour not 

 reaching quite to base of immovable finger. Legs rather stout, except for the long 

 slender, yellow, horny tips of the dactyls. 



This species, like the preceding, resembles A. nudus in the smoothness of the carapace, 

 but differs in form, character of lateral teeth and in its hairy covering.

Carapace broader than long, slightly convex, smooth to the eye, but microscopically 

 granulate, regions scarcely indicated ; sparsely hairy with very fine soft hairs, of which 

 there is a row just behind the margin of the front. Body covered with numerous very 

 small irregular dots of reddish-brown, which have nearly faded out except along the 

 frontal and antero-lateral borders of the carapace and the anterior part of the ventral
