Habitat. — According to A. Smith " this lizard is found iu the sandy 

 districts of Great Namaqualand, and where the surface of the country 

 is irregular it is generally met on the liighest spots." It also occurs in 

 Little Namaqualand and the Gi-eat Karoo (Beaufort West). 



Like the two preceding species, this Scaptira must have been directly 

 derived from the S. African Eremias of the Section Mesalina. But 

 whilst S. knoxii stands near to E. lineo-ocellata, S. ctenodadyla has 

 more in common with E. capensis, and, except for the presence of a 

 large anterior supraocular, it might be regarded as the highly 

 specialized descendant of that species.
