Three specimens are preserved in the British Museum : the types, 

 labelled "West Africa," and one from near Wushishi, N. Nigeria. A 

 fourth, from Iryan on the Niger, lias been described by Klaptocz, and 

 several from Togoland have b. en recorded by Tornier. 



This species establishes a transition from Xiirras to Eremias.

Tliis lizard, described by Schmidt from 34 specimens, one of which 

 has been presented to the Britisli Museum by the American Museum 

 of Natural History, may eventually prove to be entitled to specific rank. 

 Tlie interparietal is narrower tlian m E nitida, and there are 52 to 

 (14 scales across the middle of the body. In the specimen examined 

 by me, and of which measurements are appended, only the two anterior 

 pairs of chin-shields meet on the median line, and there is conse- 

 quently a higher number of gular scales in a longitudinal series ; 

 there are 4 supraoculars, the first and fourth very small. The pattern 

 of coloration differs considerably, there being a pair of liglit strealcs, 

 each bifurcating on the nape, bordering a black vertebral stripe.
