 a pale streak of dingy primrose-yellow; neck, 

 back, wings, and tail, oH-gi'een, — paler, and more 

 on the yellow, on the lower parts of the back to- 

 wards the tail-coverts. The feathers of the back 

 and wings are streaked down the middle with a 

 tint formed of blackish-green and hair-brown ; 

 sides of the head, throat, breast, and under parts, 

 pale wax-yellow, inclining to sulphur-yellow; 

 middle of the parts below the breast very pale 

 wine-yellow, passing into white ; across each wing 

 are two bands of primrose-yellow, and between 

 them one of black; part of the quills and tail 

 edged with pale gamboge-yellow ; legs and feet 

 pale flesh-red. The head of the female is of a 

 brownish-colour, inclining to grey where the 

 male is black ; and all the rest of her plumage is 

 of a more dingy colour. The siskin nearly re- 

 sembles the canary, termed the green variety, only 

 it is a little less, the tail being rather shorter in 

 proportion.
