COTTON-TREE SPARROW. 259 



Black Bulfmches first begin to whistle, which are 

 continued all the way up to the top of the moun- 

 tains; and, indeed, they are the only birds you hear, 

 for there are hardly any Nightingales; but they 

 have the Grey-eyed Thrush, whose notes are not 

 much inferior in sweetness but longer. In these 

 mountains hardly any cockroaches are seen, but a 

 very small kind. The wood-ant, that destructive 

 insect, is also a stranger to these mountains." 

 (MSS. iii. 131.) By the Grey-eyed Thrush, I 

 suspect he means the Glass-eye : or else the White- 

 eyed Flycatcher. 



In the valuable drawings of the Doctor, he has 

 one carefully executed, of a bird considerably larger 

 than this, which he calls the Pied Bulfinch of the 

 mountains, but which I have supposed to be the 

 present bird in the partial albinism, to which all 

 black birds seem subject. There are, however, some 

 details which make this rather uncertain. The 

 whole plumage, including the red gorge, (which is 

 rather crimson than ferruginous) is studded with 

 large white patches ; beside which there is a large 

 square spot of white, occupying the middle of the 

 wing : the outmost two tail-feathers on each side are 

 also white, and the forehead is pale yellow. Should 

 it prove to be distinct, I propose for it the name of 

 Pyrrhula RoUnsonii. 



To these Fringillada, I would add, on the autho- 

 rity of Mr. Hill, the Rose-breasted Grosbeak of 

 Wilson, (Guiraca Ludoviciana, Sw.)
