The chelipeds and legs differ from those of P. fluviatile var. ibericum, only 

 in the following particulars : — 



(1) In the chelipeds the whole of the upper and outer surface of the 

 carpus and palm, and a good part of the inner surfoce of the palm, is rugulose, 

 most so in the larger cheliped; the surface of the fingers also is rough, 

 particularly the upper border of the dactylus, which is often denticulate. 



(2) In the legs the upper border of the merus is more sharply serrulate, 

 and both borders of the propodite are more sharply spinulose ; moreover, the 

 upper border of the carpus is spinulose, and the upper border of the propodite 

 of the last three legs is longitudinally grooved so as to present a distinct double 

 edge ; again, in the 2nd and 3rd legs the breadth of the propodite is quite half 

 its length. 



Length of carapace of an adult male 1 h inch, greatest breadth 2 inches. 

 This is chiefly an Eastern Himalayan species also extending into Burma, 

 but it occurs also in the Western Himalayas :■ —
