sparsely hairy ; the inferior lateral keels on the fifth segment furnished 

 posteriorly with lobate dentiform tubercles, tree such tubercles 

 situated upon the anal lobe of the segment ; vesicle sub-globular and 

 granular. 



Chelce with normal keels developed and granular, and finely granular 

 intercarpal spaces ; hand smooth, punctured, hairy, considerably 

 wider than the brachium, the movable digit about one-third longer 

 th a n the hand-back, both digits lobate, the movable furnished with 11 

 median rows of teeth, those at the base crowded together. Legs 

 gianular and granularly crested ; the feet furnished below with two 

 rows of setiform spines. Pectinal teeth, 18-20. 



$. Smaller than 9, digits more strongly lobate ; tail five and a 

 half times the length of the carapace. Pectinal teeth, 22-26. 



Measurement in millimetres. $ . Total length 48, length of cara- 

 pace 5, of tail 27. 



Locality.— Kashmore Bund, Upper Scinde (A. V. Kemball). 



Related to B. philippsii, Poc, from Bushire on the Persian Gulf, 

 but easily distinguishable by having the tail shorter and narrower, 

 with its first segment wider than the third instead of equal to it in 

 width, and the intercarinal spaces granular instead of smooth, etc. Also 

 the pectinal teeth are more numerous in B. philippsii, being 23-26 in 

 the 9, and 27-30 in the $. 



(4.) — Buthus rugiscutis, sp. n. 



Closely related to the scorpion of« India known as T. tamulus 

 nigrolineatus or T. martensii, but smaller, rougher, with thicker tail 

 and fewer pectinal teeth. 



$. Colour. — Ranging from fulvous to fulvo-fuscous, the keels of 

 the trunk and tail usually emphasized by a black tint. 



The upper surface of the trunk entirely covered with coarse granules, 

 amongst which the normal keels stand up as granular ridges, the 

 frontal keels of the carapace not traceable for more than half-way 

 across the triangular interocular area. First four sternal plates 

 smooth, the last finely granular with four nearly smooth crests. 



Tail. —About five times as long as the carapace, thickly and coarsely 

 granular below and at the sides, the upper surface also granular 

 though less coarsely than the sides ; keels forming the normal granular 

 crests, the median lateral present on the fourth ; the segments wider
