CHAUNOPROCTUS b p . 



Chaunoproctus Bonaparte, Consp. Av. I p. 526 (1850). 



HE genus Chaunoproctus contains only one species, which is characterized 



1 by its enormous bill, the depth of the mandible being greater than 

 the distance between the nasal apertures. The cutting-edge of the 

 maxilla is nearly straight, and there is no tooth in the posterior half of the 

 maxilla. The total length is about seven to eight inches. The adult male 

 has red in the plumage, the female is brown, above and below. 



Dr. Hartert (Vogel pal. Fauna I, p. 115) is of opinion that this bird 

 is connected with Carpodacus and allies, and not with the Greenfinches and 

 Hawfinches, among which it is placed in the Catalogue of Birds in the 

 British Museum. 



CHAUNOPROCTUS FERREOROSTRIS (vig.) 



Coccothraustes ferreorostris (sic) Vigors, Zool. Journ. IV p. 354 (1828) ; id. in Beechey's 

 Voy. Blossom, p. 22, pi. 8 (1839). 



Fringilla papa Kittlitz, M6m. Acad. Imp. Sc. Petersbourg I p. 239, pi. 15 (1830); id. 

 Kupfertaf. Vog. p. 24, pi. 32, 2 (1832). 



Chaunoproctus papa Bonaparte, Consp. I p. 526 (1850) ; Bp. and Schlegel, Monogr. Loxiens 

 p. 32 pis. 37, 38 (1850). 



Chaunoproctus ferreirostris Sharpe, Cat. B. Brit. Mus. XII p. 31 (1888). 

 IGORS' original description, translated from the Latin, is as follows: 



V Dark brown; head, breast and upper part of abdomen scarlet. Bill 

 very strong, feet plumbeous. Length of body 8J, bill at gape 1^, 

 height £ ; wings from the carpus to the third quill 4£ ; tail 3, tarsus £ inches." 



In the " Catalogue of Birds," XII, p. 31, both sexes are carefully 

 described. 



It appears that only one pair, now in the British Museum, was 

 obtained during Captain Beechey's voyage. Curiously enough, Vigors 

 suggested that the brilliantly coloured adult male might be the young, the 

 female the adult bird, "as is the case in the Pine-Grosbeak" (Sic!). 



Kittlitz, who visited the largest of the Bonin Islands in May, 1828, 

 obtained a number of specimens, of which some are in St. Petersburg, 

 two in Frankfurt-a.-M., one or two in Leyden, and, I believe, in Paris.
