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 Jimenez, 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 Cienegas) on May 4,
1954.

**_Columbigallina passerina_ (Linnaeus).--The Ground Dove seems to be
uncommon in Coahuila. Van Tyne and Sutton (1937:34) saw a single Ground
Dove fly across the Rio Grande into Coahuila at Lajitas, Texas, on May
10. Findley saw one 2 mi. S and 3 mi. E San Juan de Sabinas on June 22,
1952.

**_Scardafella inca_ (Lesson).--The Inca Dove has been recorded from
two localities in Coahuila. Hellmayr and Conover (1942:510) listed it
from Sabinas. Burleigh and Lowery (1942:189) collected a male and
female on April 16 and 19, respectively, "outside the city limits of
Saltillo."

_Leptotila verreauxi angelica_ Bangs and Penard.--_Specimens examined:_
total 2: [Male] [Male] 31026-31027 (skeletons only) from 4 mi. W
Hacienda La Mariposa, 2300 ft., March 25, 1952.

The White-fronted Dove seems to be uncommon in Coahuila. Hellmayr and
Conover (1942:570) listed _L. v. angelica_ from Sabinas.

**_Rhynchopsitta pachyrhyncha terrisi_ Moore.--_Specimens examined:_
total 4: [Male] [Male] 31531-31532 from 13 mi. E San Antonio de las
Alazanas, 9345 ft., April 10, 1954, weights, 391.5 and 467.5 gms.;
[Female] 31533 from 13 mi. E San Antonio de las Alazanas, 10,000 ft.,
April 10, 1954, weight, 466 gms.; and sex ? 31534 from Mesa de las
Tablas, June, 1951.

The Thick-billed Parrot occurs in the southeastern section of the
State, where it is fairly common. Moore (1947:27-28) described this
parrot as _Rhynchopsitta terrisi_: he thought it differed decidedly
from _Rhynchopsitta pachyrhyncha_. However, Hardy and Dickerman
(1955:305-306) decided that uniting the two forms as a single species
better expresses their relationship.

Burleigh and Lowery (1942:189) reported seeing a small flock of
Thick-billed Parrots on the summit of Diamante Pass. Dickerman, in his
field
