the population of Turkeys in the Sierra del Carmen was sparse and did not range above 7500 feet into the highest pine-oak and Douglas fir areas. Baker saw Turkeys 4 mi. W Hacienda La Mariposa, 2300 feet, on March 23, 1952. William Schaldach, Jr., noted 30 Turkeys "just west of Rancho San Gerónimo" on April 9, 1950. Aldrich and Duvall (1955:22) indicated several localities in northern Coahuila where the Turkey occurs or occurred.

Grus canadensis (Linnaeus).—Sutton and Burleigh (1939a:28) remarked that a flock of Sandhill Cranes was heard "near Mayran ... on January 30."

Porzana carolina (Linnaeus).—The Sora is an uncommon spring and fall migrant in Coahuila. Amadon and Phillips (1947:577) obtained an adult male Sora at Las Delicias on August 15.

Fulica americana Gmelin.—The American Coot probably occurs in the State as a spring and fall migrant. Dickerman saw two coots 8 mi. E and 2 mi. S Americanos on May 18, 1954.

*Charadrius vociferus vociferus Linnaeus.—Specimen examined: one, ♂ 31023, from the Río Grande (=17 mi. S Dryden, Terrell Co., Texas, in Coahuila), 600 ft., March 19, 1952, weight, 82.7 gms.

In Coahuila the Killdeer seems to be uncommon. Van Tyne and Sutton (1937:28) remarked that it nested in Brewster County, Texas. The species probably nests in northern Coahuila as well; the lengths of the testes (left, 9 mm.; right, 4 mm.) of No. 31023 support this view.

Eupoda montana (Townsend).—Pitelka (1948:118) recorded one female Mountain Plover from Hipólito on February 23. Van Tyne and Sutton (1937:28) reported that the Mountain Plover nested in Brewster County, Texas. Possibly Eupoda montana nests in northern Coahuila as well.

Numenius americanus parvus Bishop.—Specimens examined: total 3: ♂ 31434 and ♀ 35406 (skeleton only) from 8 mi. E, 2 mi. S Americanos, May 19, 1954, measurements: wing, 250, 258 mm.; tail, 96, 100 mm.; tarsus, 74, 81.5 mm.; culmen, 11.2, 16.5 mm.; ♂ gonad, 6×2 mm.; and ♀ 35400 (skeleton only) from 7 mi. W San Antonio de las Alazanas, January 11, 1954.

The Long-billed Curlew is not common in Coahuila. Dickerman obtained both the specimens from 8 mi. E and 2 mi. S Americanos out of a flock of 35. Sutton and Burleigh (1939a:28) noted the Long-billed Curlew "near San Pedro ... [on] January 29."

Actitis macularia (Linnaeus).—The Spotted Sandpiper has been obtained from two localities in Coahuila. Miller (1955a:162) stated that an immature in fall migration was taken "at the tank in the western hills" of the Sierra del Carmen on September 4. Burleigh and Lowery (1942:189) found the Spotted Sandpiper "at the Chorro del Agua near Arteaga" on April 17 and 19.

Totanus melanoleucus (Gmelin).—Specimen examined: one, ♀ 31024, from the Río Grande (=17 mi. S Dryden, Terrell Co., Texas, in Coahuila), 600 ft., March 18, 1952, weight, 224 gms.

The Greater Yellowlegs is an uncommon spring and probably fall migrant in Coahuila. No. 31024 is the first record of this species in Coahuila.

Totanus flavipes (Gmelin).—Miller (1955a:162) reported that Marsh took a Lesser Yellowlegs "at the tank in the western hills" of the Sierra del Carmen on September 4.

Erolia melanotos (Vieillot).—Miller (1955a:162) reported taking a Pectoral Sandpiper on September 4 "at the tank in the western hills" of the Sierra del Carmen.

[Erolia minutilla (Vieillot).—Friedmann, Griscom, and Moore (1950:99) listed the Least Sandpiper from Coahuila.]

*Recurvirostra americana Gmelin.—Specimens examined: total 2: ♂ 31433 and ♀ 31432 from 8 mi. E, 2 mi. S Americanos, May 19, 1954.

Van Hoose (1955:302) reported a small breeding colony of American Avocets 8 mi. E and 2 mi. S Americanos "on a large grassy playa traversed by rows of creosote (Larrea tridentata)." No. 31432 was taken from a nest containing four partly-incubated eggs. Van Hoose (loc. cit.) also reported that four eggs in a second nest contained well-developed, downy young.

Steganopus tricolor Vieillot.—Wilson's Phalarope occurs in Coahuila as a spring and probably fall migrant. Van Tyne and Sutton (1937:31) saw the species several times along the Río Grande. Friedmann, Griscom, and Moore (1950:102) listed Steganopus tricolor from the Río Grande along the borders of Chihuahua and Coahuila on May 10-16.

[Larus argentatus smithsonianus Coues.—Friedmann, Griscom, and Moore (1950:104) listed this subspecies of the Herring Gull from the State.]

[Larus delawarensis Ord.—Friedmann, Griscom, and Moore (1950:103) stated that the Ring-billed Gull occurs in Coahuila.]

*Columba fasciata fasciata Say.—Specimens examined: total 3: ♂ 35401 (skeleton only) from 22 mi. S and 5 mi. W Ocampo, 7000 ft., April 6, 1954; and ♂ 32035 and ♀ 32036 from 4 mi. N, 21 mi. W Cuatro Ciénegas, 6200 ft., July 2, 1952.

The Band-tailed Pigeon is locally common in Coahuila. Miller (1955a:162) remarked that the Band-tailed Pigeon "was unaccountably rare in 1953" in the Sierra del Carmen, and said that a specimen was taken on August 7 in Vivoras Canyon. Burleigh and Lowery (1942:189) wrote that "small flocks were seen each day ... on the summit of Diamante Pass, but only on one occasion was a pair noted." Dickerman saw 10 Band-tailed Pigeons 20 mi. S Ocampo, 6000 feet, on April 4, 1954. The enlarged testes (17 mm.) of No. 32035, and an egg (38 mm. long) in No. 32036 show that the species breeds in central Coahuila.

*Zenaida asiatica asiatica (Linnaeus).—Specimen examined: one, ♀ 31025 (skeleton only), from 10 mi. S and 5 mi. E Boquillas, 1500 ft., March 4, 1952.

Miller (1955a:163) took a male White-winged Dove on April 23 "at the mouth of Boquillas Canyon at about 4900 feet" and remarked that this bird might either be a straggler or a representative of a normal breeding population (Z. a. asiatica[**Z doesn't look italic, but should be?]). On January 29 and 30, Sutton and Burleigh (1939a:29) saw White-winged Doves several times in southern Coahuila along the highway from Saltillo to San Pedro.

**Zenaida asiatica mearnsi (Ridgway).—Amadon and Phillips (1947:577) obtained an adult White-winged Dove of this subspecies at Delicias on August 14.

Zenaidura macroura carolinensis (Linnaeus).—Friedmann, Griscom, and Moore (1950:117) listed this subspecies of the Mourning Dove as a spring and fall migrant on the "Central Plateau" (Coahuila is part of the "Central Plateau,"), "as proven by banding records not indicated in literature."

*Zenaidura macroura marginella (Woodhouse).—Specimen examined: one, ♀ 34455, from 1 mi. W Jaco, June 27, 1953.

Miller (1955a:163) reported Z. m. marginella as occurring commonly in the desert border and lower canyons at the base of the mountains of the Sierra del Carmen, "but it occasionally ranged up to 6000 feet in openings in the pine-oak belt." Burleigh and Lowery (1942:189) remarked that this dove was fairly plentiful in the open desert country "about Saltillo, and was ... noted in small numbers in Diamante Valley on April 17 and 19;" they also said that the Mourning Dove was not seen above an elevation of about 7500 feet. Sutton and Burleigh (1939a:29) observed Mourning Doves along the highway across southern Coahuila. Mourning Doves were seen by Findley 2 mi. W Jiménez, 850 feet, on June 19, 1952, and 2 mi. S and 11 mi. E Nava, 810 feet, on June 15, 1952. Dickerman saw one in the Sierra del Pino on May 12, 1954. Findley saw more than one 2 mi. S and 3 mi. E San Juan de Sabinas on June 22, 1952, as did Dickerman at San Marcos (=20 mi. S Cuatro Ciénegas) on May 4, 1954.
