1915.] Chapman, New Colombian Birds. 649 
Remarks.— Although I have but a single specimen of this proposed new 
race its characters are so well-marked when compared with sixteen specimens 
of P. 1. plumbeiceps (including the type), and, furthermore, are so in keeping 
with those shown by other subspecies from the humid Pacific coast, that I 
have no hesitation in describing it. 
Cisneros, the type locality for this form, marks the known. westward 
limit of the Polioptila livida group. 
Sporophila aurita muraile subsp. nov. 
Char. subsp.— Most nearly related to S. a. ophthalmica but larger throughout, 
the black breast-band averaging narrower (nearly incomplete in one specimen), sides 
grayer, white patch at base of primaries smaller, lesser wing-coverts narrowly tipped 
with white, greater ones less frequently with white near the end of shaft. 
Type.— No. 117054, Am. Mus. Nat. Hist., © ad., La Muralla (alt. 600 ft.), 
Caqueté, Colombia; July 11, 1912; L. E. Miller. | 
Remarks.— This race is based on the comparison of three adult males 
from the type-locality with fourteen from the coast of Ecuador. Its close 
relationship to the Pacific coast race emphasizes the faunal affinity of the 
Tropical Zone at the eastern and western bases of the Andean system; 
while its characters mark an evident approach toward Sporophila lineata of 
lower Amazonia, suggesting that that species may form a link in the some- 
what remarkable chain composing the sporophila-aurita group.

Catamenia analoides schistaceifrons subsp. nov. 
Char. subsp.— Similar to C. a. analoides (Lafr.) but smaller, the male with the 
forehead, lores and chin slaty or gray and without black, the throat and breast much 
paler, pale neutral gray rather than slate-gray ; white area on the primaries at the end 
of the primary coverts wholly absent or barely suggested; margins of wing-coverts 
and inner margins of wing-quills grayer.
