NO. 3545 LIZARDS — PETERS 33 



Remarks: Uzzell, 1958, Occ. Pap. Mus. Zool. U. Mich., no. 597, 

 p. 7, indicates that the specimen Burt and Burt Hsted as Proctoporus 

 oculatus from El Ghiral may belong to P. striatus Peters, but that it 

 is not clearly so, showing several distinct differences. The record 

 certainly makes no zoogeographic sense at all, and it is likely that 

 the El Ghiral specimen represents a new species.
