652 Bulletin American Museum of Natural History. [Vol. XXXIV, 
Type.— No. 112797, Am. Mus. Nat. Hist., o ad. Paramo of Santa Isabel 
(alt. 12700 ft.), Central Andes, Columbia; Sept. 20, 1911; ile and Muiller. 
Range.— Alpine or Paramo Zone of Ecuador and the Central Andes of Colombia. 
Remarks.— As the appended table shows, this race is characterized by 
its large size, which is not equalled by that of any other known race of the 
species. Females from Santa Isabel in juvenal plumage are noticeably 
more chestnut above and more buffy below than Ecuador birds in similar 
plumage. To a lesser degree the same differences are present in birds in 
worn plumage; but individual variation in this sex 1s so great that an even 
larger series than I possess is necessary properly to appraise these differences... 
Some Ecuador birds show traces of the olive-buff auriculars which appear 
to characterize geospizopsis, but this feature is not present in Santa Isabel 
specimens. 
Specimens examined.— Colombia: Santa Isabel, 8 @ ads., 3 o im., 
3 9 ads.,2 9 imm. Fcuador: Chimborazo, 16 o ads.,5 oimm.,1 9 ad., 
4 2 imm.; Qyito, 1 9 ad. 
Phrygilus unicolor geospizopsis (Bonap.) 
Passerculus geospizopsis Bonap., Compt. Rend., XX XVII, 1853, p. 921 (Colom- 
bia =.“ Bogota,’ cf Selater, Pc. 8.4 1855; p., 160); 
Char. subsp.— Distinguished from P. wu. grandis Chapm. by its smaller size, from 
P.u. nivarius by its larger size; from both grandis and unicolor by its olive-buff, instead 
of grayish or buffy auricular region and by the suffusion of olive-buff on the chin and 
throat in the female. 
Range.— Alpine or Paramo. Zone of the Eastern Andes, Colombia. 
Remarks.— Thanks to the kind offices of Hermano Apolinar Maria, I am 
in possession of nine topotypical specimens of this currently unrecognized 
race, from the Paramo of Choachi near Bogot4. Of six adult females taken 
in October and November, and in partly worn plumage, all but one have the 
auricular region and throat markedly buffy-olive, a character which appears 
to distinguish this species. At any rate, it is not present in other Colombian 
specimens, though it is shown by some from Chimborazo. Should it prove 
to be individual or seasonal this form would differ from other northern forms 
of this group by size alone. 
Specimens examined.— Colombia: Paramo of Choachi, 3 co ads., 6 2 ads. 
Phrygilus unicolor nivarius (Bangs).
