 with a broad snout. Sumetiuies the suout is so much compressed that the canthi 

 rostrales are slightly concave, instead of straight lines. 



In all the specimens which I have examined from localities from Syria to 

 Algeria, the series of upper labials (to below the centre of the orbit) is composed 

 of five, and exceptionally si.x, scutes ; whilst in the specimens from the western 

 limits of the range of the species, this number is reduced to four by the coalescence 

 of the two posterior scutes, one very long scute bordering the lip below the anterior

half of the eye. Coalescence or division of labial shields is in Lizards of such 

 common occurrence that taxonomic value is scarcely ever attached to it. Yet it

 de Oro, and of several from Southern Algeria (Lataste coll.), every one has an 

 undivided fourth labial; whilst in all from more western localities I have found e«^^&^ 

 that shield divided into two subequal halves. To draw attention to this peculiarity 

 I have named the western form aureus.
