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 Oriental. Burleigh and Lowery (1942:198) recorded a _cahooni_-like specimen from Diamante Pass in southern Coahuila. **_Troglodytes brunneicollis compositus_ Griscom.--_Specimen examined:_ one, [Male] 32819, from 13 mi. E San Antonio de las Alazanas, July 6, 1955. The subspecies _cahooni_ and _compositus_ of the Brown-throated Wren seem to intergrade in the southern part of the State. Although No. 32819 represents the subspecies _compositus_, the somewhat whitish abdomen and the fairly large spots of the lesser wing coverts suggest some relationship with _cahooni_. In addition to the present record, Miller, Friedmann, Griscom, and Moore (1957:163) recorded _T. b. compositus_ from southern Coahuila at Sierra Guadalupe. The record of _T. b. cahooni_ from Sierra Guadalupe (Ridgway, 1904:588) I suspect probably represents _T. b. compositus_ or an intergrade between _compositus_ and _cahooni_. The date (July 6) on which No. 32819 was obtained 13 mi. E San Antonio de las Alazanas suggests that this bird was resident there. *_Thryomanes bewickii eremophilus_ Oberholser.--_Specimens examined:_ total 3: [Male] 32088 from 2 mi. W Jimenez, 850 ft., June 20, 1952; [Female] 31061 from 4 mi. W Hacienda La Mariposa, 2300 ft., March 24, 1952, weight, 10.8 gms.; and [Male] 31660 from the north foot of Sierra Guadalupe (=10 mi. S, 5 mi. W General Cepeda), 6500 ft., April 21, 1953, weight, 13 gms. Bewick's Wren occurs commonly in Coahuila. Miller, Friedmann, Griscom, and Moore (1957:160) reported that, in Coahuila, _T. b. eremophilus_ "intergrades in the eastern and southern sections with _T. b. cryptus_ and _T. b. murinus_, respectively." The slightly darker coloration of No. 31660, suggesting a resemblance to _T. b. murinus_, is the only evidence of intergradation of _T. b. murinus_ and _eremophilus_ that I have found.
