CETJSTACEA OF THE MEEGUI AEOHIPELAGO. 99 



feebly toothed, the teeth of the index being the larger. The 

 mobile finger is nowhere longitudinally grooved, but appears 

 minutely granular when exatniued 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. I 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 difi'ering 

 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 T. 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.
