71. Sporophila castaneiventris Cab. 
Sporophila castaneiventris Cabanis in Schomburgk, Reisen Brit. Guiana iii. p. 679 (1848.—Cumaka, 
coast of Brit. Guiana) ; Hellmayr, Nov. Zool. xiv. p. 353 (Humaytha). 
Spermophila castaneiventris Pelzeln, l.c. p. 225 (Borba). 
No. 833. ¢ ad., Marmellos, 19. xii. 1907. “Iris brown, feet and bill black.”—

Cf. Nov. Zool. xiv. p. 353 (Humaytha), 
Left bank : Humaytha (Hoffmanns). 
The single male, obtained on Mr. Hoffmann’s first journey, agrees well with 
Bahia skins. ] 
74, Myospiza aurifrons (Spix). 
Tanagra aurifrons Spix, Av. Bras. ii. p. 38. pl. 1. fig. 2 (1825.—“in provincia Bahia ”’—errore ! 
We substitute Fontebou, Rio Solimoéns); Hellmayr, Abhandl. Akad. Wissensch, Miinchen,

Coturniculus peruanus Pelzeln, l.c. p. 230 (Borba).

Widely distributed in Amazonia. M. aurifrons is evidently specifically distinct 
from the preceding form. ]

Tanagra gularis Linnaeus, Syst, Nat. xii. 1. p. 316 (1766.—ex Brisson : “ America” ; we fix Cayenne 
as type locality). 
Paroaria gularis Pelzeln, l.c. p. 228 (part. : Borba), 
Right bank: Borba (Natterer). 
Natterer’s examples, for the loan of which I am indebted to Dr. Lorenz, of 
Vienna, agree well with others from Cayenne and Lower Amazonia ; perhaps they 
have not quite so much black round the eye. 
Farther south, on the Rio Guaporé (Villa Bella de Mattogrosso), it is replaced 
by P. g. cervicalis-Scl.,* which extends into Eastern Bolivia (Mojos, etc.).. Cf.
