_Platypsaris aglaiae albiventris_ (Lawrence).--The Rose-throated Becard, if it occurs in Coahuila at all, is rare in the State. Without giving any specific locality, Sclater (1857:74) described _Pachyrhamphus aglaiae_ from Coahuila. Hellmayr (1929:202) considered Sclater's record as representing _Platypsaris aglaiae albiventris_ (Lawrence). *_Tyrannus vociferans vociferans_ (Swainson).--_Specimens examined:_ total 2: [Male] 32064 from 7 mi. S, 4 mi. E Bella Union, 7200 ft., June 24, 1952; and [Female] 31650 from the north foot of Sierra Guadalupe (=10 mi. S, 5 mi. W General Cepeda), 6400 ft., April 15, 1953. The small number of records of Cassin's Kingbird in Coahuila is surprising, for I would expect the species in most areas of the State between 6000 and 7000 feet. All Coahuilan records are from the southeastern part of the State. Burleigh and Lowery (1942:193) found it "on infrequent occasions in the arid country near Saltillo." Miller, Friedmann, Griscom, and Moore (1957:71) reported that _T. v. vociferans_ nested in Coahuila on July 7. The size of the testes (15x7 mm.) of our specimen from near Bella Union also indicates breeding. **_Muscivora forficata_ (Gmelin).--_Specimen examined:_ one, [Female] 32063, from 12 mi. N, 12 mi. W Jimenez, 850 ft., June 19, 1952. The status of the Scissor-tailed Flycatcher in Coahuila is uncertain. Although the condition of the gonads of No. 32063 was not recorded by the collector, the late date (June 19) on which is was obtained suggests that this female was a resident in northeastern Coahuila. Findley saw a Scissor-tailed Flycatcher 2 mi. S and 11 mi. E Nava, 810 feet, on June 15, 1952. Dickerman saw one 4 mi. N San Isidro on May 10, 1954. Miller, Friedmann, Griscom, and Moore (1957:69) recorded this flycatcher from Sabinas on April 12. No other records of _Muscivora forficata_ in Coahuila have come to my attention, but the species probably occurs in the State in migration. *_Myiarchus crinitus crinitus_ (Linnaeus).--_Specimens examined:_ total 3: [Female] 32065 from 12 mi. N, 12 mi. W Jimenez, 850 ft., June 19, 1952; and [Male] 32066 and [Female] 32067 from 2 mi. W Jimenez, 850 ft., June 20, 1952.
