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

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

 fourth, from Irvau on the Niger, has been described by Klaptocz, aud 

 several from Togolaud have b' en recorded by Tornier. 



This species establishes a transition from Nucras to Eremias. 



Var. OARAMBENSIS. 



Eremias nifida garambensis, Sclimidt, Bui!. Anier. Mus. N. H. sxxix, 

 1919, p. 511, figs. 



This lizard, described l»y Schmidt from 34 specimens, one of which 

 has been presented to the British Museum by the American Museum 

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

 The interparietal is narrower than m E nitida., aud there are 52 to 

 64 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 aud fourth very small. The pattern 

 of coloration differs considerably, there being a pair of light streaks, 

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