DRYOPE CRENATIPALMATA. 191 



pair of legs have the hand subtriangular ; the superior 

 margin is arcuate, but not continuous with that of the 

 wrist ; the palm occupies nearly the entire length of the 

 inferior margin, it is very oblique, irregularly waved, 

 minutely crenulate, and defined by a prominent tubercle 

 or blunt tooth, tipped with a strong spine ; the 

 finger is as long as the palm, having the inner margin 

 serrated, except at the apex. The second pair of legs 

 have the hand nearly twice as broad as long, with the 

 upper and lower margins subparallel ; the inferior angle 

 produced; the palm concave, having the deepest part 

 near the finger ornately pectinated ; near the articulation 

 of the finger there are several simple sharp-pointed 

 perpendicular teeth, succeeded by two or three lobes 

 or tubercles, surmounted with four teeth that spread on 

 each side like a fan, and lastly, with seven or eight 

 long, comb-like teeth, just within the limits of the 

 inferior angle of the palm, the last but one of which is 

 twice the length and size of the others (fig. h"). The 

 finger is strongly serrated upon the inner margin. The 

 last three pairs of w T alking legs have the antero-distal 

 extremities lobed, and the fingers robust and curved. 

 The caudal appendages decrease posteriorly in length ; 

 the branches are shorter than the peduncle, slightly 

 spinous, a long apical spine tipping every branch, of 

 which the upper or outer is the longer in the ante- and 

 penultimate pairs, but the inner one is the longest in the 

 ultimate. The tail-piece is circular, with a small point 

 at the dorsal extremity. 



This species was sent to us by Mr. Gosse, who took it 

 off Weymouth.
