l 23 on a slope at the mouth of Boquillas Canyon of the
Sierra del Carmen; he presumed it to be a transient.

_Zonotrichia leucophrys leucophrys_ (Forster).--_Specimen examined:_
one, [Male] 30243, from 1 mi. SW San Pedro de las Colonias, 3700 ft.,
February 8, 1951.

The White-crowned Sparrow is a fairly common migrant or winter visitant
in Coahuila. Miller, Friedman, Griscom, and Moore (1957:393) recorded
_Z. l. leucophrys_ from Sabinas on March 16 and February 23. Burleigh
and Lowery (1942:212) remarked that "small flocks of White-crowned
Sparrows were seen at infrequent intervals in thickets and stretches of
underbrush on the outskirts of Saltillo on April 18 and again on April
24 ... [and] near a small town some twenty miles west of Saltillo on
April 22." Specimens that Burleigh and Lowery (_loc. cit._) collected
"near Saltillo" were identified as _Z. l. leucophrys_.

_Zonotrichia leucophrys gambelii_ (Nuttall).--_Specimen examined:_ one,
[Male] 31117, from Sierra de la Encantada (=38 mi. S, 23 mi. E
Boquillas), 4400 ft., March 15, 1952.

Miller (1955a:177) noted _Z. l. gambelii_ on April 27 at 4600 feet in
Boquillas wash in the Sierra del Carmen. Hellmayr (1938:568) listed _Z.
l. gambelii_ from Sabinas.

_Zontrichia leucophrys oriantha_ Oberholser.--This subspecies has been
recorded from Sabinas on April 25 and Hipolito on November 5 (Miller,
Friedmann, Griscom, and Moore, 1957:393).

_Melospiza lincolnii lincolnii_ (Audubon).--_Specimen examined:_ one,
[Female] 31595, from 20 mi. S Ocampo, 7000 ft., April 5, 1954,
measurements: wing, 58 mm.; tail, 50 mm.; weight, 12 gms.

Lincoln's Sparrow seems to be a fairly common migrant or winter
visitant in Coahuila; _M. l. lincolnii_ is the common subspecies.
Burleigh and Lowery (1942:212) found this sparrow only in a grain field
situated between a small pond and a narrow stream on the outskirts of
Saltillo; the four specimens collected were identified as _M. l.
lincolnii_. No. 31595 was obtained in a pine-oak association.

_Melospiza lincolnii alticola_ (Miller and McCabe).--Miller, Friedmann,
Griscom, and Moore (1957:398) listed _M. l. alticola_, which seems to
be uncommon in Coahuila, from Sabinas on March 14.

_Melospiza lincolnii gracilis_ (Kittlitz).--Miller (1955a:177) took an
unsexed representative of _M. l. gracilis_ on April 7 in Carboneras
Canyon of the Sierra del Carmen at 6700 feet. This occurrence is at the
extreme eastern range of this subspecies.
