Birds from Algeria. 195 



on the Little Atlas Mountains. It was there fairly common, 

 and was generally to be found on rough stony ground. The 

 organs of the birds shot were in breeding-condition, and 

 although I found no nest, there is no doubt that they were 

 nesting. 



Al.AUDA AHBOREA L. 



? ad. H. Meskoutine, March 22. 



? ad., <S ad. H. R'Hira, April 20 and May 5. 



The Wood-Lark was fairly common in the northern part 

 of the country. It was breeding at II. R'Hira at the end of 

 April, and in the Little Atlas in May up to an altitude of 

 about G000 feet. 



AMMOMANES DESERT! ALGERIENSIS Shai'pe. 



<J ad., ? ad., ? ad. Biskra, March 12 & 13. 

 This form of the Desert-Lark was common in the rocky 

 hills round Biskra. 



Galerida cristata arenicola Tristr. 



Hartert, Yog. pal. Fauna, p. 232. 



Ad. Biskra, March 15. 



Dr. Hartert has kindly identified this specimen for me. 

 It was the only example of G. cristata which I obtained in 

 Algeria. 



Galerida theckl^e superflua. 



Hartert, Vog. pal. Fauna, p. 238. 



No. 5. ? ad. Biskra, March 8. 



No. 16. ? ad. Biskra, March 12. 



These two specimens are very puzzling. No. 5, Dr. Hartert 

 tells me, is typical G. t. superflua, the other he considers 

 a reddish variety of that form. It is quite as red as the 

 supposed G. t. deichleri Erlanger, which Dr. Hartert has 

 united with G. t. superflua owing to the two forms being 

 found in the same locality. Although Crested Larks tend 

 to vary according to their environment in a remarkable way, 

 yet those found in any one region are generally constant 

 in their coloration ; and if my birds are really of the same 

 race, we have, in this case, a striking exception to the rule.
