onal specimens at the type locality, a conglomerate
cliff along the Rio Marquez. These will be reported by him in his
forthcoming study of the genus.

~Anolis dunni~ Smith

_Anolis dunni_ Smith, Copeia, no. 1:9, May 10, 1936.--Agua
del Obispo, Guerrero, Mexico.

Arteaga (3); 19 km. S of Arteaga.

Three females from Arteaga (UMMZ 119075) have snout-vent lengths of 41,
41, and 44 mm. In life the pale grayish brown dorsum was marked with
dark brown; the belly was white, and the throat was pale pink. All have
a dark interorbital bar and dark vertical bars on the upper labials. In
two specimens there are only scattered dark flecks on the dorsum; in the
third there is a dark postorbital stripe, a dark lateral stripe, and
four narrow transverse bands on the body. A male from 19 kilometers
south of Arteaga (UMMZ 119076) having a snout-vent length of 49 mm. had
in life a tan dorsum, a broad white stripe from the ear to the groin,
scattered small white spots on the dorsum, and indistinct pale
cream-colored spots on the posterior surfaces of the thighs. This male
has the dark labial bars, but lacks the dark interorbital bar, found in
the females. The large rose-pink throat fan extends to about the middle
of the belly. In all of the specimens the middorsal scales are keeled
and much smaller than the smooth pavementlike or slightly imbricate
ventrals. All have two gulars in contact with the mental, five scales
between the nasals, five scales (not including the first labials) in
contact with the rostral, and four rows of loreals. In these characters
these specimens agree well with _Anolis dunni_ from Guerrero, as
diagnosed by Davis (1954b).

Previously _Anolis dunni_ has been reported only from the vicinity of
Agua del Obispo, Guerrero, a locality situated at an elevation of about
900 meters in pine-oak forest in the Sierra del Sur. All known close
relatives of _Anolis dunni_ occur only in Guerrero: _A. taylori_ Smith
and Spieler from Acapulco, _A. gadowi_ Boulenger from Tierra Colorado,
_A. liogaster_ Boulenger, and _A. omiltemanus_ Davis from Omiltemi. The
present specimens from elevations of about 900 meters in riparian stream
vegetation and oak forest represent the northern known limits of this
group of _Anolis_.
