*_Colinus virginianus texanus_ (Lawrence).--_Specimens examined:_ total 9: [Male] 29408 and [Female] 29409 from 1 mi. S, 9 mi. W Villa Acuna, April 2, 1950, weights, 169.5 and 174.7 gms., [Male] 29410 and [Female] [Female] 29411-29413 from 3 mi. W, 1 mi. S San Geronimo, April 9, 1950, weights, 152.6, 158.6, 158.2, 159.0, and 152.8 gms.; and [Male] [Male] 32032-32034 from 9 mi. S, 11 mi. E Sabinas, 1050 ft., June 13 and 14, 1952. The Bobwhite is locally common in northeastern Coahuila. Aldrich and Duvall (1955:18) indicated that _C. v. texanus_ has been recorded from two separate localities in northeastern Coahuila and from several localities in Texas along the Rio Grande. Findley saw Bobwhites 2 mi. S and 3 mi. E San Juan de Sabinas on June 22, 1952. The specimens of Bobwhite from 3 mi. W and 1 mi. S San Geronimo seem to extend the known range of _texanus_ nearly 100 miles west. The sizes of the testes (11, 16, 15, 15 mm.) of Nos. 29408, 32032-32034, respectively, indicates breeding by the Bobwhite in Coahuila. *_Callipepla squamata pallida_ Brewster.--_Specimens examined:_ total 16: [Male] 29414 from 1 mi. S, 13 mi. W Villa Acuna, April 4, 1950; [Male] [Male] 29415-29417 from 11 mi. W Hacienda San Miguel, 2200 ft., April 4, 1950, weights, 205.3, 198.6, and 182.7 gms.; [Female] [Female] 31019-31021 from 10 mi. S, 5 mi. E Boquillas, 1500 ft., March 2 and 4, 1952, weights, 184.4, 180 and 154.2 gms.; [Male] 34454 from 2 mi. SSE Castillon, 4050 ft., June 29, 1953, weight, 169 gms.; [Male] 29418 and [Female] 29419 from 8 mi. N, 2 mi. E La Babia, April 8, 1950; [Male] [Male] 32023-32024, [Male] 32026, [Female] 32025, and [Female] 32027 from 5 mi. N, 19 mi. W Cuatro Cienegas, 3250 ft., July 6, 1952; and [Male] 32640 from 2 mi. W Paila, July 3, 1955. The Scaled Quail is common in Coahuila. The subspecies _pallida_ occurs in northwestern Coahuila south to Sierra de los Alamitos. Intergrades of _pallida_, _castanogastris_, and _squamata_ are present in the central part of the State. No. 32640, obtained 2 mi. W Paila, has some resemblance to _squamata_. Five specimens of _pallida_ from the central part of Coahuila (5 mi. N and 19 mi. W Cuatro Cienegas), show little or no approach toward _squamata_. Miller (1955a:162) stated that two of the Scaled Quail collected in the Sierra del Carmen show no approach to the race _castanogastris_ of eastern Coahuila nor to _C. s. squamata_ of southern Coahuila. From the specimens that I have examined, I judge that the range of _pallida_ extends as far south as the Sierra de los Alamitos rather than only to the northwestern part of Coahuila as reported by Aldrich and Duvall (1955:17). In northeastern Coahuila _pallida_ seems to intergrade with _castanogastris_; No. 29414 has an indistinct rusty chestnut patch on its abdomen, thus resembling _castanogastris_.
