previously compared with Spix' type. The throat is white, somewhat shaded 

 with cinereous towards the foreneck, the elongated feathers of the pilenm are 



extensively white on (heir basal portion, ami the feet blackish brown. Specimens 

 from the Dcayali (Santa Croz) and Peruvian Amazons (Loretoyacu) in the Tring 

 Museum differ by their paler brown legs, by having the forehead and occiput of 

 a clearer olive-grey, and especially by the throat being slightly washed with lmffy. 



23. Cypsnagra ruficollis pallidigula n. snbsp. 

 I „ \agra ruficollis Lichtenstein, Fere. Jhihl. Berliner Mus. p. 30 (182:?. — S. Paulo).] 



No. 1290. 6 ad., Eumaytha, 24. ix. 06. "Iris dark brown, feet and bill 

 black." — Type of the subspecies. — Wing 79; tail 62; bill 14| mm.

 Wing 78 ; tail 63; bill 14 mm. 



These two birds differ from a very large series of time ( '. r. ruficollis (Lcht.) 

 from S. Paulo, Goyaz, Mattogrosso and Bahia in having the throat and foreneck 

 light bnff (Ridgw. Nomencl. v. 13) instead of deep cinnamon-rufous. The rump 

 is pure white (not creamy buff); the breast, abdomen and lower tail-coverts are 

 considerably paler, creamy white, and there is no trace of the ochraceous patch on 

 the flanks always to be seen in the typical form. The bill is rather shorter, stouter, 

 and more convex. 



Both specimens are in perfect adult plumage, with the head, back and wings 

 of a deep glossy black. The British Museum possesses two skins of the new form, 

 said to be from Bahia (Luschuath). This locality, however, is certainly erroneous, 

 both examples being of the unmistakable handsome Ceara-make. The pale- 

 throated form would thus appear to be rather widely distributed in the more 

 northern districts of Brazil, where it evidently replaces the typical race. 



In young birds of the latter, the throat is also much paler than in adults, of 

 a dull ochraceous yellow, but such specimens can always easily be distinguished 

 from C. r. pallidigula by the dull brownish black coloration of the back, etc., and 

 by the presence of a narrow bnffy yellow superciliary streak. It may be worth 

 mentioning that the birds collected by D'Orbigny in the province of Chiqnitos, 

 Eastern Bolivia, beloug to the dark-throated, typical form of Southern Brazil. I 

 am much indebted to my friend M. Menegaux, of the Paris Museum, for the loan 

 of these specimens. 



24. Nemosia flavicollis centralis n. subsp. 



No. 1253. c? ad., Humaytha, 17. ix. 06. "Iris brown, feet plumbeous, bill 

 black, below yellow." Wing 72; tail 55; bill 14 mm. — Type of subspecies. 



Intermediate in size between N. f. flavicollis (Vieill.) and S.J. melanoxantha 



(Lcht.); but bill quite as long and strong as in the latter form; yellow of the 

 rump extended far up to the middle of the back, as in N. f. insignis Sri. ; under 

 parts pure white, as in N. f. flavicollis, with but a few blackish cross-bands on the 

 foreneck. Differs from all the known races of N. flavicollis by having the head, 

 mantle and shoulders deep velvety black (instead of brownish black). 



In the type from Humaytha, the rump, throat and crissum are of the same 

 clear citron yellow as in N. f. melanoxaitl/ia, while an adult male from Tilotilo, 

 Northern Bolivia, which in other respects perfectly agrees with it, has these parts
