e 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:
[Male] 35401 (skeleton only) from 22 mi. S and 5 mi. W Ocampo, 7000
ft., April 6, 1954; and [Male] 32035 and [Female] 32036 from 4 mi. N,
21 mi. W Cuatro Cienegas, 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,
[Female] 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_). 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, [Female] 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
