122 IIE. G. A. BOULENGEE ON THE REPTILES 



by Lallemant from the western part of the Province of Oran, and from Tebesa, in the 

 Province of Constantine. Dr. Strauch purchased specimens stated to have been obtained 

 at Batna. M. Lataste did not come across it in Algeria, and thinks some of the reports 

 of its occurrence may be due to confusion with the uniform fuliginous variety of 

 Trogon ophis wiegman n i.

 Tangier, Tetuan, the Zaffarine Islands, Larache, Casablanca, Coreina, Mogador, and 

 between Mogador and Morocco. It is found in the three provinces of Algeria, and 

 occurs as far south as Biskra. The only Tunisian locality is Tamesmida, between 

 Ferriana and Tebesa, where specimens were collected by M. Lataste.
