Sierra del Pino (=5 mi. S, 3 mi. W Acebuches), May 12, 1954,
weight, 41 gms.

Miller (1955a:174) found this subspecies of the Hepatic Tanager "in the
pine-oak belt at 7000 feet on April 12 [in the Sierra del Carmen], when
a male was seen and a female taken." No. 31526 was with a female when
taken; this male was not fat and its testes were not enlarged. The size
of the wing (105.5 mm.) of No. 31526 represents the extreme maximum in
this subspecies.

_Piranga flava hepatica_ (Swainson).--Miller, Friedmann, Griscom, and
Moore (1957:303) stated that _P. f. hepatica_ is found in northwestern
and central Arizona and southwestern New Mexico south into the
highlands of Mexico, west of the Sierra Madre Oriental, to Oaxaca and
in winter and migration extends eastward and south to Chiapas. These
authors remarked also that _P. f. dextra_ occurs in the mountains east
of the continental divide in New Mexico and western Texas south through
eastern Mexico to Chiapas. Specimens of the Hepatic Tanager from
Coahuila in winter might well be either _P. f. hepatic_ or _P. f.
dextra_. Miller, Friedmann, Griscom, and Moore (_loc. cit._) recorded
migrants of _P. f. hepatica_ from the Sierra de Guadalupe on April
24-27.

*_Piranga rubra rubra_ (Linnaeus).--_Specimens examined:_ total 6:
[Male] 32129, [Male] 32132, and [Female] 32133 from 12 mi. N, 12 mi. W
Jimenez, 850 ft., June 18 and 19, 1952; [Male] 32130 from 2 mi. W
Jimenez, 850 ft., June 20, 1952; and [Male] 32131 and [Female] 32134
from 2 mi. S, 11 mi. E Nava, June 15, 1952.

This Summer Tanager occurs in northeastern Coahuila. The specimens from
12 mi. N and 12 mi. W Jimenez, 2 mi. W Jimenez, and 2 mi. S and 11 mi.
E Nava are typical representatives of _P. r. rubra_. The large testes
(12 mm.) of No. 32129 and the well-developed brood patch of No. 32134
are evidence of breeding by this subspecies in the State. Heretofore
this subspecies has not been recorded from Coahuila.

*_Piranga rubra cooperi_ Ridgway.--_Specimens examined:_ total 4:
[Male] [Male] 32828-32829, [Male] 32831, and [Female] 32830 from
Parras, July 4, 1955.

This subspecies of Summer Tanager seems to occur throughout Coahuila
except in the northeastern section of the State. Miller, Friedmann,
Griscom, and Moore (1957:302) listed _P. r. cooperi_ from Sabinas and
Sierra de Guadalupe. Miller (1955a:174) saw a Summer Tanager in a
canyon in the Serranias de Burros, about 40 miles east of the Sierra
del Carmen on April
