marked that his individual may
best be considered an intergrade between _mexicanus_ and
_excubitorides_, being "somewhat closer to the former." Burleigh and
Lowery (1942:201) obtained a male _L. l. mexicanus_ "in the open valley
just below the summit of Diamante Pass on April 23" that was typical of
this subspecies. Burleigh and Lowery (1942:201-202) suggested that _L.
l. mexicanus_ breeds in southeastern Coahuila. Sutton and Burleigh
(1939a:39) took a typical representative _L. l. mexicanus_ at Mayran on
January 30.

_Lanius ludovicianus gambeli_ Ridgway.--Miller, Friedmann, Griscom, and
Moore (1957:214) recorded this subspecies from Hipolito on November 6.

*_Vireo atricapilla_ Woodhouse.--_Specimens examined:_ total 4: sex ?
32099-32100 from Sierra del Pino (=6 mi. N, 6 mi. W Acebuches), 5250
ft., July 3, 1952; and [Male] [Male] 31493-31494 from 16 mi. E, 18 mi.
N Ocampo, May 8 and 9, 1954, enlarged testes.

The Black-capped Vireo seems to breed as far south as central Coahuila.
Miller (1955a:171-172) reported this vireo as a summer resident in "the
low catclaw-dominated scrub in the lower washes of Boquillas Canyon and
its side valleys, at 4600 to 4800 feet" in the Sierra del Carmen.
Dickerman found the Black-capped Vireo common on the dry scrub and oak
hillside habitat 16 mi. E and 18 mi. N Ocampo.

_Vireo griseus noveboracensis_ (Gmelin).--Ridgway (1904:184) recorded
this subspecies of the White-eyed Vireo "west to Sabinas." Miller,
Friedmann, Griscom, and Moore (1957:220) also recorded _V. g.
noveboracensis_ from Sabinas on May 25. I suspect that the specimen of
_V. g. noveboracensis_ from Sabinas that was taken on May 25 was a
vagrant. _V. g. noveboracensis_ may occur in Coahuila as a migrant or
winter visitant; however, I do not believe that representatives of
_noveboracensis_ normally are resident in Coahuila.

*_Vireo griseus micrus_ Nelson.--_Specimen examined:_ one, [Male]
32101, from 2 mi. W Jimenez, 850 ft., June 20, 1952, measurements:
wing, 58 mm.; tail, 43.5 mm.; culmen, 10 mm.; tarsus, 19 mm.

This subspecies of the White-eyed Vireo breeds in Coahuila. Miller,
Friedmann, Griscom, and Moore (1957:221) recorded _V. g. micrus_ from
Sabinas on March 9 and May 14. The enlarged testes (5x3 mm.) of No.
32101 and the date (June 20) on which it was obtained suggest breeding
in Coahuila.

_Vireo huttoni stephensi_ Brewster.--This subspecies of Hutton's Vireo
occurs in southeastern Coahuila as a migrant.
