Localities listed by Miller, Friedmann, Griscom, and Moore (1957:92) of _E. d. salvini_ and _E. d. immemoratus_ are south of twenty-three degrees north latitude whereas the range of _E. d. occidentalis_ includes parts of Nuevo Leon north of twenty-three degrees north latitude (_occidentalis_ intergrades with _hellmayri_ at Cerro Potosi, Nuevo Leon, [Miller, Friedmann, Griscom, and Moore, _loc. cit._]). Thus, the specimen from Diamante Pass probably is either _E. d. hellmayri_ or _E. d. occidentalis_. **_Empidonax fulvifrons pygmaeus_ Coues.--Miller, Friedmann, Griscom, and Moore (1957:95) listed this subspecies of the Buff-breasted Flycatcher from the Sierra Guadalupe on April 21. This record represents the eastern limit of the range of _E. f. pygmaeus_ in northeastern Mexico. **_Contopus pertinax pertinax_ Cabanis and Heine.--Burleigh and Lowery (1942:194) obtained one female Coues' Flycatcher "in a small gully just below the summit of Diamante Pass." _Contopus virens_ (Linnaeus).--I judge from the paucity of records in the literature that the Eastern Wood Pewee is uncommon in Coahuila. Burleigh and Lowery (1942:194) obtained two males at the Chorro del Agua, and remarked also that "it is possible that as far west as Saltillo, this species is a rather uncommon transient." Ridgway (1907:519) listed _Contopus virens_ from Sabinas. *_Contopus sordidulus veliei_ Coues.--_Specimens examined:_ total 2: [Male] 31467 from Sierra del Pino (=5 mi. S, 3 mi. W Acebuches), May 14, 1954; and [Male] 31653 from the north foot of Sierra Guadalupe (=10 mi. S, 5 mi. W General Cepeda), 6400 ft., April 19, 1953. Specimen No. 31467 of the Western Wood Pewee was obtained in pine and oak vegetation by Dickerman. Ridgway (1907:523) reported _Contopus sordidulus veliei_, under the name _Myiochanes richardsonii richardsonii_, from Sierra Encarnacion. Amadon and Phillips (1947:578) obtained a specimen of _C. sordidulus_ from Las Delicias. Miller, Friedmann, Griscom, and Moore (1957:83) remarked that the Western Wood Pewee breeds in the State. _Nuttallornis borealis_ (Swainson).--Several records of the Olive-sided Flycatcher from Coahuila are present in the literature. Miller (1955a:167) reported it as a migrant in the desert at the base of the Sierra del Carmen on April 24. Miller, Friedmann, Griscom, and Moore (1957:82) reported this species from Ocampo on June 16. Amadon and Phillips (1947:578) obtained one at Las Delicias on August 16. Burleigh and Lowery (1942:194) collected two males "near the summit of Diamante Pass" on April 14. *_Pyrocephalus rubinus mexicanus_ Sclater.--_Specimens examined:_ total 3: [Male] 32060 and [Female] 32061 from 12 mi. N, 12 mi. W Jimenez, 850 ft., June 19, 1952; and sex ? 32062 from 2 mi. W Jimenez, 850 ft., June 20, 1952.
