312 ME. E. I. POCOCK ON SCOEPIONS 



4th 12-5, 8-5 ; 5th 13-5, 7-8 ; width of vesicle 7 ; width of bra- 

 chium 4, of hand 4*2 ; length of hand-back 5*6, of movable digit 12. 

 The measurements of the d may be compared with those of 

 the cJ of liosoma and Hunteri given above. From this it is 

 apparent that in having the tail long and slender granimanus 

 and Hunteri are much alike, but that the manus is larger even 

 than in Hunteri and is, in addition, covered with granules. 



The measurements of the $ may be compared with the fol- 

 lowing taken from a $ of the typical liosoma from the crater at 

 Aden. Total length 118, of carapace 12'5, of tail 70 ; length and 

 breadth of its segments : 1st 9, 93 ; 2nd 10, 10 ; 3rd 10-5, 10-2 ; 

 4th 11-8, 10-3 ; 5th 13, 8-8 ; width of vesicle 7, of brachium 4, 

 of manus 3-8 ; length of hand-back 5-5, of movable digit 12'7. 



This shows clearly that the tail in liosoma is much thicker and 

 shorter. Of the latter the Museum has 59 specimens from 

 S. Arabia. 



Loo. Zeyla in Somali-land. 5 specimens, including types of 

 cJ and $ , obtained by Mr. E. "W. Gates. Also two examples of 

 apparently the same form, but paler, from the Somali coast 

 presented to the British Museum by H. M. Phipson : the 

 larger of these is a $ measuring 120 mm,, the carapace being 

 just over 12 and the tail 75. And two others ( d" $ ) from the 

 crater at Aden, the $ measuring 128 mm., of which the tail is 

 79 and the carapace 13*2. These two examples are of peculiar 

 interest, because from the fact that they were taken in company 

 with a large number of examples of the typical liosoma, it appears 

 that the two remain perfectly distinct in the same spot, and exist 

 side by side without blending. 



The Museum also has a $ example of apparently this form 

 from Massowah, and another nearly allied form from Kihma- 

 njaro and Mianzine obtained by Mr. P. J. Jackson. But more 

 material is required from these latter localities before we can be 

 sure of the identity of the two specimens. 



Paeabutuus pallidtjs, sp. n. 



Colour. Legs, mandibles, palpi, tail, and lower side of trunk 

 entirely pale yellow ; carapace and terga darker, reddish or 

 brownish yellow. 



Carapace as long as tail-segments 1st -f ^ of the second, 

 entirely covered, including the ocular tubercle and the area im- 

 mediately below the median eyes, with fine granules. 



Terga also covered with granules, which are exceedingly fine
