Ereviias. 233 



Particulars of Specimens Examined. 



1. Length from snout to vent (in millimetres). 2. Scales across middle of 

 body. 3. Longitudinal series of ventral plates. 4. Transverse series of ventral 

 plates. 5. Plates in collar. 6 Gular scales in a straight median series. 

 7. Femoral pores (right and left if differing). 8. Lamellae under fourth toe.

Same explanation for the other tables in this genus. 



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, has been described by Klaptocz, and 

 several from Togoland have bien recorded by Tornier. 



This species establishes a transition from Nucras to Eremias. 



Var. GARAMBENSIS. 



Eremias nitida garambensis, Schmidt, Bull . Amer. Mus. N. H. xxxix, 

 1919, p. 511, figs. 



This lizard, described by Schmidt from 34 specimens, one of vpliich 

 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 in E nitida, and there are 52 to 

 64 scales across the middle of the body. In the specimen examined 

 by me, and of which measuremeats ai-e 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 light streaks, 

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