Hardy saw a male _T. b. eremophilus_ at Parras on July 4, 1955.
Ridgway (1904:557) listed _T. b. eremophilus_ from Saltillo in April
and as breeding at Sabinas.

The sizes of the testes (8 mm.; 6x4 mm.) of Nos. 32088 and 31660,
respectively, suggest breeding 2 mi. W Jimenez and Sierra Guadalupe.

**_Thryomanes bewickii cryptus_ Oberholser.--Miller, Friedmann,
Griscom, and Moore (1957:161) recorded _T. b. cryptus_ from Saltillo.

*_Thryothorus ludovicianus berlandieri_ Baird.--_Specimens examined:_
total 3: [Male] 32086 from 12 mi. N, 12 mi. W Jimenez, 850 ft., June
19, 1952; sex ? 32087 from 2 mi. W Jimenez, June 20, 1952; and [Female]
31063 from 8 mi. N, 4 mi. W Muzquiz, 1800 ft., April 1, 1952, weight,
18.3 gms.

One subspecies of the Carolina Wren, _berlandieri_, occurs in Coahuila
in the northeastern section of the State. Ridgway (1904:547) recorded
_T. l. berlandieri_ from Sabinas. The fact that No. 32086 was a
juvenile suggests that the Carolina Wren breeds 12 mi. N and 12 mi. W
Jimenez.

*_Campylorhynchus brunneicapillum couesi_ Sharpe.--_Specimens
examined:_ total 6: [Male] 29429 from Canyon del Cochino (=16 mi. N, 21
mi. E Piedra Blanca), 3200 ft., April 6, 1950; [Male] 31064 from 7 mi.
S, 2 mi. E Boquillas, 800 ft., February 29, 1952, weight, 38.1 gms.;
[Female] 31066 (skeleton only) from 10 mi. S, 5 mi. E Boquillas, 1500
ft., March 5, 1952; [Male] 31637 from La Gacha (=La Concha), December
1, 1953, weight, 40 gms.; [Male] 31638 from 18 mi. S Ocampo, December
16, 1953; and sex ? 29557 from 7 mi. S, 1 mi. E Gomez Farias, 6500 ft.,
November 18, 1949, weight, 41 gms.

This subspecies of the Cactus Wren occurs throughout Coahuila except in
the extreme southeastern section of the State, where the subspecies _C.
b. guttatus_ occurs. Miller (1955a:169) found _C. b. couesi_ breeding
and occupying the open swales and mesas at the base of the mountains of
the Sierra del Carmen. Burleigh and Lowery (1942:198) found _C.
brunneicapillum_ "to be rather scarce and decidedly local in its
distribution" and observed an occasional bird "in the open desert
country west of Saltillo." Miller, Friedmann, Griscom, and Moore
(1957:151) recorded _C. b. couesi_ "south to [the] vicinity of
Monclova."

No. 29557 does not have any characters of _C. b. guttatus_; its under
tail coverts and flanks have roundish black spots, rather than black
bars as in _C. b. guttatus_.
