The name under which I describe these Algerian specimens has 

 been applied in the past to very different lizards, and has given rise 

 to much discussion. 



I have first of all no hesitation in regarding the Acanfliorlacfi/lus 

 discovered near Oran l)y M. Doumergue as specifically identical with 

 A. vaillanti, Lataste, stated to be from Somaliland. Geographical 

 considerations alone seem to have induced Doumergue to propose 

 for it the name of oranensi)^. Does, however, .4. vdilhnif! really come 

 from Somaliland ? 



In his report on the collection made in Somaliland liy Revoil, 

 Vaillant has recorded several specimens of Acanfhodacfylus, under 

 the names of A. vulgaris, A. savlgnyi, and A i^avigtiyi, var. schreiberi. 

 These specimens have since been re-examined by Lataste and by 

 Anderson, and the two former names have been shown to refer partly 

 to A. pardalis, partly (one specimen only) to a species described as 

 new by Lataste under the name of A. vailJanti, the third to A.iteufellatus.
