ermediate between
_atricristatus_ and _dysleptus_ were listed from Cuidad Muzquiz and
Sabinas by Dixon (_loc. cit._:189), as _dysleptus_ but were shown on
his map (_loc. cit._:184) as _atricristatus_. Our Nos. 32084 and 32085
(wing, 71, 71, tail, 63, 64 mm.) are small and fall in the upper range
of size for _atricristatus_ to which the specimens are here referred.

*_Auriparus flaviceps ornatus_ (Lawrence).--_Specimen examined:_ one,
[Male] 31056, from Sierra de la Encantada (=38 mi. S, 23 mi. E
Boquillas), 4400 ft., March 15, 1952.

The Verdin occurs up to about 5000 feet in Coahuila. Miller (1955a:168)
reported that "this desert species followed the catclaw scrub up the
washes to about 4800 feet, the limit of such habitat" in the Sierra del
Carmen and also gave evidence of breeding by the Verdin in Coahuila.
Amadon and Phillips (1947:578) reported a nest of _Auriparus flaviceps_
at Las Delicias. Burleigh and Lowery (1942:197) obtained a single
specimen "in an arroyo a few miles east of Saltillo" and a single
specimen "about twenty miles west" of Saltillo. Ridgway (1904:421)
reported _A. f. ornatus_ [he referred to it as _A. f. flaviceps_] at
Monclova. Hellmayr (1934:88) listed _A. f. ornatus_ from Jaral. Findley
saw a Verdin 2 mi. S and 3 mi. E San Juan de Sabinas on June 22, 1952.

The size (wing, 50 mm.; tail, 43 mm.) of No. 31056 is small for typical
representatives of _A. f. ornatus_. The yellow of the head of No. 31056
is darker than that of the other subspecies of the Verdin, and I have
accordingly allocated the specimen to _A. f. ornatus_.

*_Psaltriparus melanotis lloydi_ Sennett.--_Specimens examined:_ total
5: [Male] 31058 and [Female] 31057 from 37 mi. S, 21 mi. E Boquillas,
4100 ft., March 13, 1952; [Male] 31060 and [Female] 31059 from Sierra
de la Encantada (=38 mi. S, 23 mi. E Boquillas), 4400 ft., March 15,
1952; and [Male] 35407 (skeleton only) from Sierra del Pino (=5 mi. W,
3 mi. S Acebuches), 6200 ft., May 14, 1954.

The Black-eared Bushtit is common in Coahuila. Typical representatives
of _P. m. lloydi_ in the northern part of the State range from 4100
feet to 8000 feet. Miller (1955a:168-169) reported _P. m. lloydi_
breeding in the Sierra del Carmen. Marsh and Stevenson (1938:287)
obtained a male in the Sierra del Carmen at El Jardin. The size of the
testes (3.5 mm.) of No. 31058 suggests breeding by the Black-eared
Bushtit 37 mi. S and 21 mi. E Boquillas.
