hatch 13 mi. E San Antonio de las Alazanas on July 6,
1955.

_Certhia familiaris americana_ Bonaparte.--_Specimens examined:_ total
2: [Female] 31612 from the base of Don Martin Dam, November 27, 1953,
skull partially unossified; and [Female] 31587 from 20 mi. S Ocampo,
6500 ft., April 5, 1954, weight, 7 gms.

This subspecies of the Brown Creeper can be considered a sparse winter
visitant to Coahuila. Van Hoose (1955:302) reported that Nos. 31612 and
31587 constitute the southernmost records of _C. f. americana_ and
represent the first records of occurrence of _americana_ in Mexico.

_Certhia familiaris montana_ Ridgway.--Miller (1955a:169) reported this
subspecies of the Brown Creeper, which he assumed to be a winter
visitant or a migrant, in the Sierra del Carmen. He (_loc. cit._)
remarked also that the higher conifers would seem to constitute
favorable habitat for nesting by the Brown Creeper, but did not find
any evidence of a breeding population of creepers in the Sierra del
Carmen. Miller, Friedmann, Griscom, and Moore (1957:143) reported _C.
f. montana_ from San Lazaro Mountain on November 9.

**_Certhia familiaris albescens_ Berlepsch.--_Specimens examined:_
total 3: sex ? 32805 from 13 mi. E San Antonio de las Alazanas, July 7,
1955; [Male] [Male] 31610-31611 from 3 mi. S, 13 mi. E San Antonio de
las Alazanas, 8900 ft., January 12, 1954.

Miller, Friedmann, Griscom, and Moore (1957:143) reported _C. f.
albescens_ from "southern Coahuila." Nos. 31610-31611 and 32805
represent the only other records of this subspecies from the State. The
date (July 7) on which No. 32805 was obtained suggests that this bird
was a resident 13 mi. E San Antonio de las Alazanas.

_Troglodytes aedon parkmanii_ Audubon.--_Specimen examined:_ one, sex ?
29556, from 1.5 mi. N Parras, 5500 ft., November 10, 1949, weight, 9.8
gms.

Burleigh and Lowery (1942:197) recorded the House Wren "in small
numbers about Saltillo where occasional birds, presumably migrants,
were noted in thickets or stretches of underbrush fringing cultivated
fields." They obtained a single male "on the outskirts of Saltillo."
Hellmayr (1934:218) listed _T. a. parkmanii_ from Sabinas.

*_Troglodytes brunneicollis cahooni_ Brewster.--Typical representatives
of this subspecies of the Brown-throated Wren occur in northern
Coahuila. In the Sierra del Carmen, Miller (1955a:170) found _T. b.
cahooni_ that in no way suggested _compositus_ of the Sierra Madre
Orient
