Type 



Habitat. — Becluianaland. Described from two female specimens 

 from Mochudi, received by the South African Museum from Mr. J. 

 Feuton, along with examples of Eremias luguhris and Ichnotroiiis 

 capensis from the same locality. 



This species is closely related to the typical E. lineo-ocellatu, dift'ering, 

 as I thought when describing it, iu the very rugose upper head-shields, 

 the absence of projecting scales in front of the ear, and the lower 

 number of subdigital lamellse (21 instead of 24 to 28). The number 

 of scales across the body is low (51 or 56 as against 53 to 73), as 

 compared with E. lineo-ocellata. 



However, the large series of E. lineo-ocellata which I have latelv 

 been able to examine, thanks to the kindness of Miss Wilman, have 

 shown greater variation iu that species, some specimens having the 

 upper head-shields strongly rugose, and the auricular denticulation 

 absent. So tliat the lower number of subdigital lamellte remains the 

 only absolute difference by which to define E. aspera. It is therefore 

 highly probable that this remarkable form will prove not to deserve 

 specific rank.
