The name under which I describe these Algerian specimens has 

 been applied in the past to very different lizards, and has ^'iveu rise 

 to much discussion. 



I have first of all no hesitation in regarding' the Acanthodactijlin 

 discovered near Oran by M. Doumergue as specifically identical with 

 A. caillanti. Lata-te, stated to be from Somaliland. Geographical 

 considerations alone seem to have induced Doumergue to prop<j-e 

 for it the name of orannaaig. Does, however, A. laillanti really come 

 from Somaliland r 



In his report on the collection made in Scjmaliland hy Ecvoil, 

 Yaillant ha- recorded several specimens of Acanthodactylus, under 

 the names of A. cnltfaris, A. goviijnyi, and A snvignyi, var. seltr^ihuri. 

 These speciuieiis have since been re-examined by Lataste and liv 

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

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

 new by Lata-te under the name of .1. iY</7'(7/i^', the third to A.>--uteUatu^.
