The following are descriptions of these three forms : — 



SCOTEINUS SCHLIEFFENI BEDOUIN, Subsp. n. 



Rather smaller in size than typical >S'. schlieffeni. 



Colour above nearest to " wood-brown," but a much paler shade 

 than that given by Ridgway ; below still paler, i. e., the colour 

 containing more white. 



Dimensions of type : — 



Head and body 41-8 mm. ; tail 28-8 ; forearm 30 ; ear 9-5. 



Skull— gi-eatest length 12-2 ; interorbital breadth 3-3 ; brain- 

 case breadth 6-3 ; breadth across upper jaAv at level of m" 5-6 ; 

 post-canine tooth-row 3 '5. 



Hah. Lahej, near Aden. 



Type. Adult. B.M. no. 95.6.1.53. Collected on the 12th 

 March, 1895, and presented to the Museum by Col. J. W. 

 Yerbury. 



A second specimen taken at the same time only differs in being 

 slightly smaller. The difference in coloration between these 

 specimens and a series of four taken by Mr. W.'Dodson, 18th Sept., 

 1899, at Sheik Othman, only 10 or 12 miles distant — nearer the 

 coast — is most marked. These latter do not differ materially 

 from specimens from the south coast of the Red Sea, which we 

 provisionally refer to typical schlieffeni.
