(3855a) Myospiza manimbe columbiana Chapm. 



Myospiza manimbe columbiana Chapm., Bull. Am. Mus. Nat. Hist., XXXI, 

 1912, p. 162 (CaU, CoL). 



Char, sitbsp.— Upperparts much darker and more broadly streaked than in 

 M. m. manimbe, the crown and back of about the same color. 



Apparently confined to the Tropical Zone. We have five specimens from 

 Call, and three from La Manuelita, in the Cauca Valley, one from near 

 Honda and five from Chicoral, in the Magdalena Valley. The latter, as 

 before remarked (I. c), are paler than columbiana and more nearly resemble 

 specimens from the middle Orinoco region.

(3856) Myospiza aurifrons (Spix). 



Tanagra aurifrons Spix, Av. Bras., II, 1825, p. 38, pi. i, fig. 2 (Fonteboa, Rio 

 Solimoens) . 



Of this Amazonian species, which appears not to have been before 

 recorded from Colombia, we have six specimens from Florencia and five 

 from La Morelia in the Caqueta region.

(3856a) Myospiza cherriei Chapm. 



Myospiza cherriei Chapm., Bull. A. M. N. H., XXXIII, 1914, p. 183 (Villavi- 

 cenoio, CoL). 



Char, sp.- — Similar to Myospiza manimbe but much paler, the plumage with no 

 chestnut, the crown essentially Kke the back, the breast with no dusky band, the 

 yellow of head more extensive, encircling the eye and basally crossiag the forehead, 

 outer primary shorter, equalKng the seventh instead of the sixth (from without); 

 outer taU-feathers shorter; bill more slender, the mandible plumbeous rather than 

 brownish in color. 



Known only from the llanos at the base of the Eastern Andes. 



This species is intermediate between Myospiza manimbe (Licht.) and 

 M. aurifrons (Spix) (= peruviana auct.), in fact, it materially closes the gap 

 between these quite unlike forms. In the general coloration of the upperparts 

 it more nearly resembles manimbe, but in its strongly graduated tail, white 

 underparts, extent of yellow on the head, color and shape of the bill, it 

 appears to be more nearly related to aurifrons. Its wing formula is inter- 

 mediate in character, the outer primary being shorter than in manimbe and 

 longer than in aurifrons.
