132 F. Stoliczka — Notes on the Indian Species of Thelyphonus. [No. 2, 



and beginning with two somewhat larger denticles at the base of the 

 process ; this fourth joint also has a minute denticle on the lower anterior 

 corner. The fifth joint is invariably conspicuously shorter and thinner than the 

 fourth, anteriorly with a strong depressed, sharply pointed process which is 

 somewhat more coarsely serrated posteriorly than anteriorly ; the lower 

 anterior corner of this joint has two denticles, the anterior of which is 

 somewhat stronger than the corresponding denticle of the preceding joint. 

 The sixth joint, or movable claw, is somewhat longer than the process of 

 the fifth, slightly inwardly curved, sharply pointed, above and below with a 

 finely serrated edge, internally on the concave side with a smooth ridge, and 

 two equally smooth ones are externally on the convex side. 



The first pair of feet are thin ; the terminal eight tarsal joints are 

 shorter than the preceding metatarsal one. The coxal and femoral joints 

 of the three other pair of feet are thick, depressed, very densely and finely 

 granular. 



Colours. Full grown specimens are above brown, slightly darker on the 

 cephalic portion of the thorax and on the cheliceres, except near their ends ; 

 all the feet from their tibial joints to the end are red, and each joint of the 

 three posterior pairs has near its terminal upper edge a black dot ; the last 

 joint of the maxillse, the ocular tubercle and the claws are black. On the 

 lower side the cheliceres, the prosternum, the abdomen are more or less dark 

 brown, the coxse of the feet and the sternum are yellowish brown and the 

 feet reddish brown. 



The following are the dimensions of a specimen of very nearly the same 

 size as the one figured by Koch as T. proscorpio. 



Total length of cephalotlaorax and abdomen, 37 mm. 



Length of cephalothorax, 13.6 „ 



„ ,, abdomen, including the three terminal joints, 23. „ 



„ „ cheliceres, measured above, without basal joint, 17.5 „ 



„ „ first pair of feet, excluding the basal or coxal joint,. 44. „ 



„ „ second ditto, 25. ,, 



„ „ third ditto, 26.5 „ 



„ „ fourth ditto, , 36. „ 



„ „ abdominal seta, ditto, , , 36. „ 



In young speciniens (with a total length of about 20 mm.) the abdomen 

 is often slightly longer in proportion to the length of the cheliceres, but there 

 is not the least difference in structure. The body and cheliceres are 

 olivaceous brown, the process of the fourth joint, the whole of the fifth and 

 sixth joints of the cheliceres red ; coxal and femoral joints of all feet 

 olivaceous, the remaining joints and the seta yellowish red. On the lower 

 side, the basal joint of cheliceres is pale brown with the spinal processes 

 red, the three following olivaceous brown, the two terminal red ; prosternum
