rra del Carmen and observed young just
out of the nest on April 25. He remarked also that specimens of the
House Finch from the Sierra del Carmen seem to show no intergradation
toward _frontalis_. Burleigh and Lowery (1942:206) noted _C. m.
potosinus_ at "Saltillo, in the desert country west of there, at the
Chorro del Agua, and in the open valley south of Diamante Pass."
Miller, Friedmann, Griscom, and Moore (1957:316) listed breeding by _C.
m. potosinus_ at El Diamante on July 6. Dickerman also saw the House
Finch at San Marcos on May 4, 1954, and Hardy saw it at Parras on July
4, 1955. No. 32147 had a distinct brood patch; the largest ovum of No.
32146 was 7 mm. in diameter. No. 32145 was a juvenile male.

The University of Kansas specimens agree well with descriptions of _C.
m. potosinus_ as given by Moore (1939:195). No approach toward _C. m.
frontalis_, _centralis_, or _nigrescens_ is exhibited by any of these
specimens. No. 31675, from Pico de Jimulco in southwestern Coahuila, is
paler above and below than any other specimens of _C. m. potosinus_.
Also the crown of No. 31675 is suffused with more red than in typical
representatives of _C. m. potosinus_.

**_Spinus pinus pinus_ (Wilson).--_Specimen examined:_ one, sex ? 33219
(skeleton only) from 13 mi. E San Antonio de las Alazanas, 9950 ft.,
July 6, 1955.

On April 5, 7, and 21, Miller (1955a:175) recorded winter visitant or
vagrant flocks of Pine Siskins in the Sierra del Carmen. Miller,
Friedmann, Griscom, and Moore (1957:318) listed _S. p. pinus_ south to
Sierra Guadalupe. Dickerman saw Pine Siskins 13 mi. E San Antonio de
las Alazanas on April 10, 1954.

_Spinus pinus macropterus_ (Bonaparte).--Miller, Friedmann, Griscom,
and Moore (1957:319) recorded a vagrant _S. p. macropterus_ from 50 mi.
S Monclova, 2850 feet, on November 9.

_Spinus tristis pallidus_ Mearns.--_Specimen examined:_ one, [Female]
31101, from Fortin (=33 mi. N, 8 mi. W San Geronimo), 3300 ft., March
28, 1952, weight, 11.5 gms.

The American Goldfinch is an uncommon migrant or winter visitant in
Coahuila. Hellmayr (1938:296) recorded _S. t. pallidus_ from Sabinas.
Fortin and Sabinas are the only places in Coahuila where _S. t.
pallidus_ has been collected. No. 31101 is a typical representative of
_S. t. pallidus_.

**_Spinus psaltria psaltria_ (Say).--_Specimens examined:_ total 7:
[Male] [Male] 32148-32149 and [Female] 32151 from 12 mi. N, 12 mi. W
Jimenez, 850 ft., June 19, 1952;
