CRUSTACEA OF THE MERGUIL ARCHIPELAGO. 99 
feebly toothed, the teeth of the index being the larger. The 
mobile finger is nowhere longitudinally grooved, but appears 
minutely granular when examined under a lens; the index pre- 
sents a slight longitudinal groove on its outer surface, and the 
pointed tips cross one another. 
The smaller hand of the male measures only two thirds of the 
length of the larger hand, and the upper margin of the palm is a 
little granular or rugose. The fingers of the smaller hand are 
distinctly longer than the palm; and they meet along the whole 
length of their inner margins, and do not at all gape; they 
have pointed crossing tips ; and both fingers are slightly longitu- 
dinally grooved, and appear minutely granular along these grooves. 
The inner margins are feebly toothed. JI may observe that 
in the larger hand of young male specimens the fingers are less 
gaping and the palm appears slightly granular on its upper 
margin. 
The anterior legs of the female are much smaller than those of 
the male, and are also somewhat unequal, although never differing 
so much from one another as do those of the male. The wrist 
presents a more rugose upper surface. The hands are similar to 
the smaller hand of the male as regards their outer appearance, the 
fingers being slightly longer than the palm and meeting along 
their whole inner margins. The palm of the larger hand appears 
slightly granular on its outer surface, and the palms of both 
hands on their upper margins. The fingers have pointed tips, 
and are feebly denticulated along their inner margins, and in 
the fingers of the smaller hand of the male they are faintly lon- 
gitudinally grooved and minutely granular along the margins of 
these grooves. 
The ambulatory legs present the usual slender form, and 
are similar to those of 7. Stoliczkana except that their dacty- 
lopodites, the outer and inner surfaces of which are quite smooth 
and plain, or scarcely convex, never present any traces of lon- 
gitudinal grooves or ridges, and are, moreover, less tapered 
towards their tips, and therefore somewhat obtuse, as the spines 
with which their joints are armed are continued close to their 
tips.
