34 BANGS — COSTA RICAN BIRDS 
C’. zeledoni does not apparently range so far south as the Volcan de 
Chiriqui, the large number of specimens, taken by Brown on this 
voleano, being all typical of C. pileatus. 
Spinus xanthogaster bryanti (Cassin). 
I now have a fine suite of specimens of Spinus xanthogaster from 
Costa Rica, including a number of adult males. Unfortunately 
I have but one adult male from Colombia (a Bogota skin) for com- 
parison, but this one is so very different from any of the Costa Rican 
specimens that I have not the slightest doubt that bryanti (type 
locality, Dota, Costa Rica) is a perfectly valid subspecies. 
The Colombian skin —true 8S. xanthogaster (DuBus) — is 
slightly smaller than the Costa Rican specimens, but has an actually 
larger, heavier bill. Its under parts — breast, belly and under 
tail coverts — are much darker, more saturated yellow; the yellow 
spot in the wings is smaller; and the yellow at the base of the tail 
feathers is much more restricted, occupying considerably less than 
half of the length of the feathers, whereas in every Costa Rican 
adult male it occupies more than half of the length of the feathers. 
Emberizoides sphenura lucaris subsp. nov. 
Type, from Boruca, Costa Rica, o\ adult, no. 18,590, coll. of E. A. and 
O. Bangs, collected May 5, 1906, by C. F. Underwood. 
Characters.— Similar to E. sphenura hypochondriacus (Hellmayr) of 
Frances, Volean de Chiriqui, Panama, and of about the same size except 
that the tail appears to be a little longer; but color of chest, sides and 
flanks much brighter and darker buffy brown; rump more rufescent; 
sides uniform buffy brown, the flanks only narrowly striped with dusky 
(in EL, sphenura hypochondriacus both sides and flanks are heavily striped 
with blackish).
