of scales varies at Aden, as Professor Boettger \ who was the first to 

 record it from there, mentions that his specimen or specimens had 

 only 22 rows of scales round the body. 



The type of the species was obtained in Abyssinia by Hemprich 

 and Ehrenberg. 



"Almost all the specimens obtained were dug out of the sand."

This species attains to a considerable size at Aden and its neigh- 

 bourhood, but adheres to the typical form first described from Egypt 

 by Eorskll, and the number of scales round the body varies from 

 28 to 30. Some Aden specimens differ somewhat in coloration 

 from Egyptian individuals, as the black and white spots are more 

 strongly developed, the white more so than the black, and the 

 arrangement in transverse lines is less apparent. In the intensity 

 of the markings these Aden lizards distinctly recall those on the 

 Berbera side of the Gulf of Aden. 



Mr. Shopland, of Aden, presented a specimen of this Lizard to 

 the British Museum some years ago. 



" Very common in Aden, Shaikh Othman, and Lahej. I was at 

 first inclined to think that a Skink seen in the stony water-courses, 

 high up on the Shum-Shum range, was of a different species, but, 

 although I did not get a specimen, I finally came to the conclusion 

 that it was the same."
