321. THE SUB-ALPINE WARBLER Sylvia subalpina, 

 Bonelli, is a resident in Algeria, common in winter 

 in the desert, according to Taczanowski. 



322. THE LESSER WHITETHROAT Sylvia curruca 

 (Linnaeus), is a winter visitor to Algeria, frequenting 

 the oases. Whether this species breeds in the coun- 

 try is uncertain, but I observed it as far south as 

 Biskra and sparingly distributed, in May. 



323. THE COMMON WHITETHROAT Sylvia cinerea, 

 Bechstein, is a winter visitor to Algeria. Whether 

 it breeds or not I cannot say, but I found it,

 generally distributed in May, from Biskra north-

 flew on board our steamer as we were crossing the
