intervening lines of smaller white spots, alongside of tliem ; a 

 more or less interrupted, narrow, wliitc line along the upper 

 margin of the dark lateral band, and a more or less orange 

 line below it ; a dusky line from the nostril to the eye, with the 

 upper labials faintly speckled with brown ; upper surface of head 

 immaculate, or finely spotted with brown ; the lateral brown 

 band is prolonged on to the sides of the base of the tail; upper 

 surface of limbs marbled with brown, with one or two wbitish 

 spots on the bind limbs. Under surface pure white. 



These specimens have been compared with the types of the 

 species, from whicli they differ in having the scales immediately 

 external to tbelOth rowof ventrals partaking more of the character 

 of dorsal than of ventral scales. Some of these scales, rarely 

 however, assume the character of ventrals, so that eleven ventrals 

 are present in some, the odd number being due to the scale of the 

 oppot^ite side not having taken on the full characters of a ventral. 

 These cases of asymmetry are not recorded in the accompanying 

 table, but their existence suggests that the difference betv;een 

 the types and these Hadramut specimens, in the number of 

 their ventrals, will be bridged over when more materials from 

 additional localities are examined.

The two males are distinguished by the presence of pure 

 white spots on the head and on the anterior part of the body, 

 while the females are not. One female is of considerable interest, 

 as the way in which the dark spots are arranged in obliquely 

 disposed lines across the body, and the presence on some of the 

 scales of a white central dart, recall the coloration of Chalcides 

 occllatus, Forskal. This tyj^e of coloration is also occasionally 

 present in Eumeces schneideri, Daud., of which Mr. Boulenger 

 has shown me some specimens, from Hoana, near Alexandretta, 

 with tlie characteristic markings of G. {G.) ocellatiis, Forskal, so 

 perfectly reproduced that the lizards might, at first sight, be 

 mistaken for it.
