84 BANGS — NEW SANTA MARTA BIRDS 
Mr. Ridgway, compared very carefully the Santa Marta series 
with numerous Bogota examples of X. s¢réatzico//is in the National 
Museum. As a result, the Santa Marta bird appeared to us to 
show even more difference than I remembered. 
The new species differs from X. s¢riaticollis of the Bogota region of Colom- 
bia and of Ecuador, in being much yellower, less fulvous, below — the throat 
and superciliary streak maize yellow; in lacking the stripes on top of head, 
the feathers being edged with dusky, giving a scaly instead of striped appear- 
ance; in having the pileum decidedly more olivaceous. 
Measurements. — Adult male, type: wing, 85.5; tail, 69.5; tarsus, 18.5; 
exposed culmen, 17. mm. Adult female, topotype, no. 6155: wing, 78.5; tail, 
67.; tarsus, 17.; exposed culmen, 16. mm.

Type, from San Miguel, Sierra Nevada de Santa Marta, Colombia, 7500 
feet altitude, 9 adult, no. 6149, coll. of E. A. and O. Bangs, collected Jan. 29, 
1899, by W. W. Brown, Jr. 
On comparing the two specimens of the Santa Marta bird with a 
large series of P. drunnescens from Chiriqui, I find it to differ very 
much in color. Itis true I have had no Bogota examples for com- 
parison, but Sclater’s original plate and description agree very well 
with the Chiriqui examples, and if the Bogota and Chiriqui forms 
are different, they are certainly much more like each other, than 
is either like the Santa Marta form. 
The new species differs from P. dyanmnescens in having the ground color of 
under parts much darker, richer brown — less olivaceous; in the throat being 
ferruginous, instead of pale ochraceous; the tear-shaped shaft spots on under 
parts rather small, much darker, more ferruginous in color, and more sharply 
contrasted with ground color, the dusky borders of the spots blacker and more 
conspicuous ; under tail coverts with deeper-colored — ferruginous — shaft 
stripes, which are much more conspicuous and better defined than in P. drun- 
nescens ; back and rump richer, redder brown, less olivaceous brown.
