Suhspecijic characters. — Throat and breast grayish vinaeeous-buff, 

 instead of being essentially pure white; flanks and abdominal region 

 much deeper, the former nearly ochracoous-tawny; ear coverts and 

 sides of the neck grayer, less cinnamon-rufous; upper parts aver- 

 aging darker, with less cinnamon-rufous, especially anteriorly.

Thrivadectes scrutator Taczanowski, Proc. Zool. Soc, 1874, p. ]37 (Maraynioc,

I have no material for comparison.

(2493) XENOPS RUTILUS HETERURUS Cabanis and Heine. 



Xenops heteruriLS Cabanis and ITeine, Mus. Hein., vol. 2, 1859, p. 33 (Colombia). 

 Xenops riitilus hcterurus Berlepsch and Stolzmann, Ornis, 1906, p. 92 (Idma). 



These specimens are slightly smaller than Colombian examples, but 

 essentially agree with them in color. Found in the Subtropical Zone.

(2508) MARGARORNIS PEBLATA (Lesson). 



Sittasomus perlatus Lesson, Echo du Monde Sav., Aug. 11, 1844, col. 275 (Boeotd. 



El Pinon, above Fusiigasugd, altitude 9, GOO feet). 

 ? Margurornis perlata peruviana Cory. Field Mus. Pub., No. 167, 1913, p. 291 

 (Tambo Ventija, 10 miles ea^t ol' Moliuopampa, Peru). 



Found in the Temperate Zone. These specimens have the throat 

 and spots of the under surface more yellow than in most specimens 

 of true perlata, but they can be matched by at least half a dozen 

 specimens in a series of perlata from Colombia. I find no difference 

 in the coloration of the upper parts of adults from the two countries. 



Cedrobamba (12,000 feet), 3; above Torontoy (14,000 feet), 2. 



(2511) PBEMNORNIS GUTTATA (Lawrence). 



Margarornis guttata Lawrence, Ann. Lye. New York, vol. 8, 1867, p. 128 (Quito). 



This specimen can be matched by one from near Bogotfi,, which I 

 have referred to guttata on the basis of the agreement of an immature 

 Colombian specimen, from San Antonio, with Ijawrence's type, which 

 is also immature. 



Idma, 1.
