0 (skeleton only) from 7 mi. W San Antonio de
las Alazanas, January 11, 1954.

The Long-billed Curlew is not common in Coahuila. Dickerman obtained
both the specimens from 8 mi. E and 2 mi. S Americanos out of a flock
of 35. Sutton and Burleigh (1939a:28) noted the Long-billed Curlew
"near San Pedro ... [on] January 29."

_Actitis macularia_ (Linnaeus).--The Spotted Sandpiper has been
obtained from two localities in Coahuila. Miller (1955a:162) stated
that an immature in fall migration was taken "at the tank in the

Lowery (1942:189) found the Spotted Sandpiper "at the Chorro del Agua
near Arteaga" on April 17 and 19.

_Totanus melanoleucus_ (Gmelin).--_Specimen examined:_ one, [Female]
31024, from the Rio Grande (=17 mi. S Dryden, Terrell Co., Texas, in
Coahuila), 600 ft., March 18, 1952, weight, 224 gms.

The Greater Yellowlegs is an uncommon spring and probably fall migrant
in Coahuila. No. 31024 is the first record of this species in Coahuila.

_Totanus flavipes_ (Gmelin).--Miller (1955a:162) reported that Marsh
took a Lesser Yellowlegs "at the tank in the western hills" of the

Pectoral Sandpiper on September 4 "at the tank in the western hills" of
the Sierra del Carmen.

[_Erolia minutilla_ (Vieillot).--Friedmann, Griscom, and Moore
(1950:99) listed the Least Sandpiper from Coahuila.]

*_Recurvirostra americana_ Gmelin.--_Specimens examined:_ total 2:
[Male] 31433 and [Female] 31432 from 8 mi. E, 2 mi. S Americanos, May
19, 1954.

Van Hoose (1955:302) reported a small breeding colony of American
Avocets 8 mi. E and 2 mi. S Americanos "on a large grassy playa
traversed by rows of creosote (_Larrea tridentata_)." No. 31432 was
taken from a nest containing four partly-incubated eggs. Van Hoose
(_loc. cit._) also reported that four eggs in a second nest contained
well-developed, downy young.

_Steganopus tricolor_ Vieillot.--Wilson's Phalarope occurs in Coahuila
as a spring and probably fall migrant. Van Tyne and Sutton (1937:31)
saw the species several times along the Rio Grande. Friedmann, Griscom,
and Moore (1950:102) listed _Steganopus tricolor_ from the Rio Grande
along the borders of Chihuahua and Coahuila on May 10-16.

[_Larus argentatus smithsonianus_ Coues.--Friedmann, Griscom, and Moore
(1950:104) listed this subspecies of th
