THE BIRDS OF ALGERIA. 59 



233. The Common Sparrow Passer dowpsticiis 

 (LinncTGiis), is a resident in Algeria, and widely 

 distributed throughout the towns and villages. 



236. The Tree Sparrow Passer rnontanus 

 (Linnaeus), is a rare resident in Algeria, but its 

 distribution is very imperfectly known. 



237. The Hawfinch Coccothraustes vulgaris, 

 Pallas, is a resident in Algeria, but only sparingly 

 and locally distributed, chiefly in the northern 

 slopes of the Atlas. I met with it in the evergreen 

 oak forests near Lambessa. 



238. The Greenfinch Ligiirinus chloris (Lin- 

 naeus), is a resident in Algeria, its numbers 

 being increased in winter. The resident birds, 

 confined principally to the Tell, have been dis- 

 tinguished under the name of L. aurantiiventris, 

 but the characters relied upon — a more brilliant 

 colour and smaller size — appear not to have even 

 a sub-specific value. I found the Greenfinch very 

 common near Constantine. 



239. The Serin Seriuus hnrtulanus, Koch, is a 

 resident in Algeria, but commoner in winter than 

 in summer. It is widely distributed, not only in 

 the mountain districts, but in the more northern 

 oases. I met with it in the oases of El Kantara 

 and Biskra.
