geographic races of F. aurea, which are far from being satisfactorily understood. 
Cf. my remarks in Nov. Zool. xiv. 1907, p. 6, and lc. xv. 1908, p. 26. 
This is the first record from the Madeira district, since the birds enumerated 
under EF. chlorotica by Pelzeln turned out to belong to F. chrysopasta Scl. & Salv.

Euphona Lichtensteinii Pelzeln, Zur Orn, Bras. p, 204 (Borba). 
Right bank: Borba (Natterer). Not obtained by Mr. Hoffmanns. 
Miss Snethlage has lately met with it on the Tapajéz: Goyana, Ilha do

37. Euphonia laniirostris laniirostris Lafr. & D’Orb. 
Euphonia laniirostris Lafresnaye & D’Orbigny, Syn. Av. i. in Mag. Zool. cl. ii. p. 30 (1837.— 
Yuracares, Bolivia) ; Hellmayr, Nov, Zool. xiv. p. 347 (Humaytha). 
Nos. 172, 552. dd ad., Calama, 6. vii., Jamarysinho, 14. ix. 1907—Wing 
62, 634; tail 35, 36; bill 9 mm. 
Nos. 3, 95, 173. ? 2 ad., Calama, 8, 22. vi., 6. vii. 1907—Wing 58—60; tail 
33—34 ; bill 8—9 mm. 
No. 903. ? ad., Maruins, 4. vi. 1908.—Wing 61; tail 35; bill 9 mm. 
“Tris dark brown or blackish, feet black or plumbeous, bill black.” 
The males, while fully corroborating the distinctness of E. landirostris, differ 
from the type and Natterer’s Mattogrosso examples by having the chin-angle 
narrowly bordered with blackish. The females agree, in coloration, with £. 
crassirostris Scl., from Colombia, Venezuela, etc., but have a much thicker, wider 
bill. Two (Nos. 3 and 173) have, on the upper surface here and there, especially 
on the occiput, a distinct slaty or oily gloss. The range of £. l. laniirostris is 
restricted to the Rio Madeira (Humaytha, Calama, etc.), Western Mattogrosso 
(Villa Maria, Sao Vicente, Villa Bella, Abrilongo, Chapada), and Northern Bolivia 
(Yuracares). In Central Pern it is replaced by the nearly allied E. laniirostris 
peruviana Berl. & Stolzm.t 
(38. Euphonia melanura Scl. 
Cf. Nov, Zool. xiv. p. 347 (Borba), 
Right bank: Borba (Hoffmanns). Not secured on the present occasion. 
E. melanura differs from the preceding species by its even (not emarginate) and 
entirely black tail. In E. lanitrostris the outermost rectrix (and sometimes also 
the succeeding one) shows a large white patch on the inner web. 
E. melanura is widely distributed in Upper Amazonia. ] 
39. Euphonia rufiventris (Vieill.). 
Tanagra rufiventris Vieillot, Nouv. Dict, xxxii, p. 426 (1819.—loc, ign.: “ type au Muséum 
d'Histoire Naturelle,—rapporté par Sonnerat ”). 
Nos. 229, 153. 3? ad., Calama, 2, 16. vii. 1907, “ Iris brown, feet and bill 
black.” —Wing 61; tail 35; bill 9—10 mm. 
Agreeing with specimens from Eastern Ecuador. For the first time recorded 
from the Rio Madeira, though widely distributed in Upper Amazonia,
