SERINUS SERINUS 195 



in the coast districts. It differs from C. citrlnella not only in the 

 brown coloration of the back, but also in having the rump less brightly 

 coloured, and the forehead, cheeks, chin and eye-region more brilliant. 

 In size C. corsicana is slightly smaller than C. citrinella, its wing 

 length averaging in the case of males 2'90 inches, as against 3"10 

 inches in G. citrinella. In addition to the pair from Corsica figured 

 by Mr. Dresser in his " Birds of Europe," which are in the Lilford 

 collection, now in my possession, I have been enabled, through the 

 kindness of Professor Giglioli, to examine the fine series of both forms 

 of this Finch existing in the Florence Museum. Some specimens 

 in this collection from Villafranca, on the French Eiviera, and from 

 Turin, appear to be intermediate between C. citrinella and C. corsicana 

 so far as the coloration of the back is concerned, but on the whole they 

 incline more to C. citrinella. 



In its general habits the Citril Finch seems to differ but little from 

 the Siskin. Fir-woods and mountain-forests are its favourite haunts 

 during the breeding season, but during migration and throughout the 

 winter lower-lying localities and the vicinity of streams are much 

 resorted to, no doubt on account of the greater abundance of food 

 to be obtained there.
