302 ME, B. I. POCOCK ON SCOEPIOKS 



pace 10, of tail 53 ; length of 1st segment 6-5, of 2nd 7"5, 

 of 3rd 8, width of the same 6"8, 6*5, 62 ; width of brachium 3"3, 

 of manus 4 ; length of hand-back 5'9, of movable digit 12"5. 



Loc. Muscat {A. Q-. Jayahar). 



It is interesting to note that these adult specimens more 

 nearly resemble the young of dimidiatus — i. e., assuming that I 

 have correctly identified the young of that species — than they do 

 the adults. We may conclude from this that the young of the 

 two species will prove to be indistinguishable, which is sometimes 

 the case with closely allied forms. 



Bttthus alticola, sp. n. (PI. IX. fig. 3.) 



S . Colour. Carapace and anterior six terga blackish green ; 

 7th tergum, tail, legs, and palpi flavous or ochraceous ; digits of 

 palpi brown with clear yellow tips (lower surface of tail perhaps 

 partially olivaceous); mandibles infuseate distally in the exposed 

 part. 



Carapace coarsely granular and keeled as in judaicus, but the 

 intercarinal area behind the eyes less granular than in that 

 species ; as long as the 1st caudal segment and one quarter of 

 the 2nd, and as long as the 4th caudal segment. 



Terga coarsely granular and strongly keeled, the three keels on 

 all the terga except the 1st strongly dentiform posteriorly ; the 

 granules on the sides of the terga subserially arranged ; on the 

 7th tergum the two lateral crests on each side are united by a 

 transTOrse row of granules, as in judaicus. 



Sterna smooth ; the external crests on the last weakly granular, 

 anteriorly and posteriorly abbreviated, the median ones smooth, 

 extending from the posterior border past the middle. 



Tail long, slender, and low, nearly 6 times as long as the 

 carapace, gradually narrowed posteriorly, the sides of each 

 segment nearly straight and parallel ; the 1st segment longer 

 than wide, the 2nd, 3rd, and 4th increasing in length, the 4th 

 twice as long as wide ; 10 keels on the 1st, 2nd, and 3rd, the 

 median lateral on the 4th represented by a few low granules ; all 

 the keels granular, the inferior median on the 1st and 2nd, 

 however, almost smooth, the granules on the upper crests in- 

 creasing in length posteriorly, the terminal granules on the 

 upper keel of the 4th dentiform ; the upper surface of segments 

 1-4 smooth, except for a few serially arranged granules ; the 

 area between the superior and the superior-lateral crest also 

 serially granular, the rest of the intercarinal spaces tolerably
