When I examined the Lizards in the Berlin Museum in 1886, 

 I regarded the type specimen of Peters's Eremias brenneri as 

 the young of Blanford's Acanthodactykis mucronaius. Now that 

 adult specimens with striated head-shields have been described, 

 under the name of Eremias edwardsii, by Mocquard, there can 

 be no doubt that I was mistaken and I gladly avail myself of 

 this opportunity for correcting my error and setting right the 

 synonymy of the two species which I had confounded : — 



Eremias brenneri. 



Eremias brenneri, Peters^ 1869. 

 Eremias edwardsii, Mocquard, 1888. 

 Somaliland. 



Eremias mucronata. 



Acanthodactylus mucronatus, Blanford, 1870. 



Pseuderemias lineolata, Boettger, 1883. 



Boulengeria mucronata, Lataste, 1885. 



Eremias brenneri, Boulenger, 1887. 



Somaliland, Abyssinia, Assab, Mount Sinai. 



These two species agree very closely in the proportions and 

 in the scaling ; E. mucronata may however be distinguished 

 from E. brenneri by the smooth upper head-shields, and the less 

 distinctly keeled dorsal scales. The number of femoral pores varies 

 from 15 to 20 in E. mucronata, from 20 to 24 in E. brenneri.
