24 buthid^:. 



or granular keels. Tail robust ; 1st segment wider than long, 

 2nd very slightly or scarcely longer than wide, 3rd one-fourth 

 longer than wide, 5th twice as long as wide ; intercarpal spaces 

 granular, the upper very sparsely so ; keels evenly granular 

 or nearly smooth, the inferior sometimes quite smooth ; median 

 lateral keel traceable on the 4th segment ; inferior lateral keel of 

 5th evenly granular throughout and passing without interruption 

 into the anal lobe ; vesicle large, granular below, as high as wide, 

 a little narrower on the 5th caudal segment, often subgeniculate 

 below the aculeus. Chelie : humerus finely granular above, with 

 granular crests ; brachium, hand, and digits rather thickly hairy 

 and without crests, except for one subdenticulate crest on the 

 anterior surface of the brachium ; hand narrow, about as wide 

 as brachium ; digits long, movable, more than twice as long as 

 the underhand and furnished with 14-15 rows of teeth. Legs 

 finely granular ; tarsi with two rows of spinules beneath. Pectinal 

 teeth from about 28-39. 



cT . Differing from $ in having the tail longer (that is to sav, 

 about six times as long as the carapace), the hand rounded, thick, 

 considerably thicker than the brachium, the length of the under- 

 hand about three quarters that of the movable digit, and the digits 

 lobate and separated at the base when closed. 



Length of adult from about 65 up to 90 mm. 



Distribution. India, from Sind in the North-west and Dehra 

 Dun throughout the whole of Western, Central, and Southern 

 India at least as far south as Madura. Certainly absent from 

 Burma and Ceylon, and apparently also from the Malabar coast 

 below the Western Ghats in Southern India, though occurriug 

 below the Ghats in the Southern Konkan. There are no data to 

 show the limits of range of the species in Eastern Bengal. Several 

 subspecies are recognizable. 



Subspecies Buthus tamulus typicus (— ? grammurus). 



Southern form : usually pale yellowish red in colour, with the 

 keels of trunk and areas adjacent often infuscate ; frequently the 

 median area of the terga is as a whole darker than the lateral 

 portion. Terga very finely and closely granular, both laterally and 

 mesially, a few coarser granules at the sides, but scarcely any 

 between the keels ; keels nearly smooth, running externally into 

 a pair of irregular and obsoletely granular, sometimes nearly 

 smooth crests ; keels of last abdominal sternum and of lower side 

 of anterior caudal segments weakly granular. Pectinal teeth28-30 

 ( $ ), 30-34 ( o" )• Length up to about SO mm. 



Distribution. Southern India: Sal.ira (J)oria) ; Kollnipur State 

 (Wray), and Belgaum above Ghats; Dowlaishweram on the 

 Godiivari ( Wgbrotv) ; Secunderabad {Roberts, Ricardo); Madras 

 (Henderson, Thurston); Nellore, Tanjore, Trichinopoly (Popert) ; 

 Madura.
