granular and densely hairy above ; the external margin of the 

 cutting-edge presents a small transverse tooth at the base and 

 appears, moreover, finely crenulate to near the tip, I^ ear the 

 latter, the inner margin of the cutting-edge is also somewhat 

 crenulate. 



The smaller chelipede is similar to the larger, but the fingers 

 are a little longer in proportion to the palm. The three following 

 pairs of ambulatory legs successively decrease in length ; the 

 anterior pair are the longest, measuring about once and a fourth 

 the breadth of the cephalothorax, and the posterior are the 

 shortest. These ambulatory legs are very hairy along their 

 margins, especially along the upper margin. The meropodites 

 and carpopodites are unarmed ; the propodites are a Little shorter 

 than the carpopodites, and measure about two-fifths of the length 

 of the meropodites. Each propodite is armed on the middle of 

 its under margin with a minute spinule and with three or four 

 similar spinules at the distal end of this margin. The dacty- 

 lopodites are very short ; each terminates in a short, acute, 

 arcuate claw, armed on its upper or external margin with a smaller 

 accessory claw ; the inner margin of the dactylopodite presents, 

 moreover, one or two minute spinules. The dorsal accessory 

 claw is directed close to and parallel with the larger terminal 

 claw. 



The legs of the fifth pair have the usual form. 

 This species differs from P. hiunguiculata, Dana, and P. obesula. 

 White, by many characters, e. _^. in its larger size, in the shape 

 of its hands, the fingers of which are much shorter than the palm, 

 in the structure of its ambulatory legs, in the animal being clothed 

 with hairs, &c. ; Folyonycc sinensis, Stimps., is doubtless another 

 species.
