DESCRIPTIONS OF SCORPIONS FROM INDIA. Ill 



granular and densely punctured ; vesicle nearly smooth, punctured, 

 sparsely granular, merely angled beneath the aculeus, without definite 

 spine. 



Chelce. — Heavy, granular ; the hand smooth, rounded, very large, 

 much wider than the brachium ; digits short, the movable about equal 

 to the hand-back in length. 



Pectinal teeth 12 in $ . Length 28 mm. 



$, with larger hand, tail posteriorly expanded ; pectinal teeth 14-5. 

 Length 21 mm. 



Locality. — Panch Mahals, in Guzerat (W. A. Wallinger). 



Resembling A. tricarinatus in possessing three tergal crests, but 

 differing essentially in having no spine beneath the aculeus of the 

 vesicle, a much broader and heavier hand, small number of pectinal 

 teeth, short spurs on the legs, etc. 



(10.) — Aechisometkus rugosus, sp. n. 



Colour. — Nearly black, variegated with yellow ; legs clear yellow 

 with black bands ; chelae blackish, with hand entirely pale yellow. 



Trunk. — Very coarsely granular above ; terga without lateral keels; 

 sterna coriaceous ; the fourth as well as the fifth granular ; the latter 

 with four granular crests, the former with two. 



Tail. — Slender, nearly four times the length of the carapace ; the 

 keels and intercarinal spaces granular ; the first three segments with 

 ten keels ; a strong spine beneath the aculeus. 



Chelae. — Slender, coarsely granular, hand narrower than brachium, 

 pectin es large, furnished with twelve teeth. 



Locality. — Raipur, Central Provinces (received from H. M. Phip- 

 son). Recognisable at a glance from the rest of the Indian species 

 of the genus by its coriaceous and granular sterna and small number 

 (12) of pectinal teeth.
