ORDER PASSERES. 151 



sopterCf Vieil. Ois. Ch. pi. xli., and low macroura. 

 Enl. 283. 1., which perhaps do not differ from each 

 other, are not widow-birds, but common grosbeaks. 



There is a gradual passage, and without any assign- 

 able interval, from the linnets to the 



Grosbeaks (Coccothraustes.) Cuv. 



Whose beak, exactly conical, is distinguished only by 

 its excessive bulk. 



This passage takes place, in the species which I 

 have had an opportunity of examining, pretty nearly 

 in the following order, the bill still increasing in 

 bulk:— 



Red-rumped Bunting. Lath. Lowia quadricolor. 

 Cuv. Emberiza quadricolor. Linn. PI. Enl. 101. 2. 

 Gros-bec longicone. Temm. 



Head and neck, blue ; back, wings, and end of tail, 

 green ; upper part of tail, tail-coverts, and middle 

 belly, red ; breast and lower belly, pale brown. Java. 



Red-billed Grosbeak. Lath. Lowia Sanguinirostris. 

 Gm. PI. Enl. 183, 2. 



Forehead above the eye, and round to the chin, black ; 

 rest of head, and above, rufous gray ; underneath, pale 

 rufous. Africa.

 Enl. 139, 2. 



Fore part of head, sides, and fore part of neck, black ; 

 hind head and above, brown ; rump, and imder breast,
