This lizard is only known to me from Werner's description of three 

 specimens from the Dii*e-Dana district and Harrar, in Abyssinia. 



Werner compares it to L. johnstonii and L. burii, but it seems to me, 

 from the description, to be nearer L. hoscee, and I am even doubtful 

 whether it deserves to be specifically separated from it.
