BIRDS FROM COSTA RICA—-WETMORE 719 
PASSERINA CIRIS PALLIDIOR Mearns: Western Painted Bunting 
Passerina ciris pallidior Mearns, Proc. Biol. Soc. Washington, vol. 24, Oct. 31, 
1911, p. 217 (Fort Clark, Kinney County, Tex.). 
I shot an adult female on November 18 in bushes near the Rio 
Liberia. 
/ ARREMONOPS RUFIVIRGATUS SUPERCILIOSUS (Salvin) 
Embernagra superciliosa SALVIN, Proc. Zool. Soc. London, 1864, p. 582 (Bebedero, 
Costa Rica). 
On October 19 I shot one of these sparrows in a thicket near the Rio 
Liberia below .own, and on November 18 in this same area secured a 
pair. The birds moved quietly about under cover, resembling in 
their mannerisms others of the genus. 
The three specimens are just completing the molt. They have the 
lateral lines bordering the crown definitely darker and blacker than 
a small series seen from farther south from La Palma, Coyolar, Santo 
Domingo, and San Gerénimo, so that possibly the birds from northern 
Guanacaste may prove to be a different form. I have not examined 
specimens from Bebedero, the type locality. 
AMMODRAMUS SAVANNARUM BIMACULATUS Swainson 
Ammodramus bimaculatus Swainson, Phil. Mag., new ser., vol. 1, June 1827, p. 435 
(Temascdltepec, México, México). 
In the open grasslands of theiHacienda Santa Maria the grasshopper 
sparrow was fairly common, though, as always, shy and rather difficult 
to secure. The three taken, secured on November 6, 13, and 15, were 
shot on the wing as they flushed before me as I walked, or rode on a 
steady horse, through the pastures. These birds were in full fall 
plumage. 
The specimens secured are dark, having black and very dark brown 
predominating above, with the median crown stripe dark buff and the 
breast band and flanks also very dark buff. The brown and the buff 
especially are darker than in fall birds of Ammodramus s. pratensis 
of the eastern United States. The relationships of the Central Amer- 
ican and Mexican birds are not entirely certain, and it is probable that 
when sufficient material is available it will be found that there are 
more than the two forms bimaculatus and cracens recognized at present.

AIMOPHILA RUFICAUDA RUFICAUDA (Bonaparte) 
Chondestes ruficauda BONAPARTE, Compt. Rend. Acad. Sci. Paris, vol. 37, 1853, 
p. 918 (Nicaragua). 
This strong, robust finch was common in the region about Liberia 
during the entire period of my observations there, so that I prepared. 
eight skins and several skeletons on October 20, 22, 26, 27, and 30 and 
November 1 and 3. The birds were found near the ground in the 
brushy, tangled growths of pastures and old fields. I recorded them
