Shaikh Othman. 1 adult. Lahej. This species attains to a considerable size at Aden and its neighbourhood, but adheres to the typical form first described from Egypt by Eorskal, 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." 16.
