DRYOPE CRENATIPALMATA. 
491 
pair of legs have the hand sub triangular ; 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 walking 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.
