~Bipes canaliculatus~ Bonnaterre

_Bipes canaliculatus_ Bonnaterre, Encyclopedie methodique,
Erpetologie, p. 68, 1789.--Mexico. Type locality restricted
to Mexcala, Guerrero, Mexico, by Smith and Taylor
(1950b:39).

Duges (1896:480) reported this species from Morelia, Michoacan. Smith
and Taylor (1950b:39), who recorded the species from three localities in
the Balsas Basin in Guerrero, rejected Duges' record. I, too, am
unwilling to accept Duges' record. Nevertheless, the species probably
occurs throughout much of the Balsas Basin. This idea is strengthened by
comments made by Storm (1939:342): "The last hard drop, that afternoon,
was down the great Cerro de los Cajones [southwest of Tacambaro], and
here in the upper forest we came upon... a lizard with front legs and
none behind ... the animal with hands and no feet that senor Smith
[Hobart M. Smith] was seeking!... They're named _Bipes caniculatus_
(_sic._)."

~Coleonyx elegans nemoralis~ Klauber

_Coleonyx elegans nemoralis_ Klauber, Trans. San Diego Soc.
Nat. Hist., 10:195, March 9, 1949.--Paso del Rio, Colima,
Mexico.

Klauber (1945:199) and Smith and Taylor (1950b:43) reported this lizard
from the coastal lowlands of Colima and Guerrero. Davis and Smith
(1953:101) reported it from 8 kilometers northeast of Temilpa, Morelos,
in the upper Balsas Basin. Specimens of this lizard have been collected
infrequently; the few locality records and limited ecological data
indicate that it inhabits dense scrub forest and tropical semi-deciduous
forest. _Coleonyx elegans nemoralis_ is to be expected on the coastal
lowlands, the seaward foothills of the Sierra de Coalcoman, and on the
lower slopes of the Cordillera Volcanica along the northern edge of the
Tepalcatepec Valley.

~Phrynosoma orbiculare orbiculare~ (Linnaeus)

_Lacerta obricularis_ Linnaeus, Systema naturae, ed. 12,
1:1062, 1789.--Mexico (by inference). Type locality
restricted to Mexico, Districto Federal, by Smith and Taylor
(1950b:97).

_Phrynosoma orbiculare orbiculare_, Smith, Trans. Kansas
Acad. Sci., 37:290, 1934.

Gadow (1905:213) inferred that _Phrynosoma orbiculare_ occurred at
elevations of more than 3000 feet in Michoacan. There are no specimens
of this species known from Gadow's collections made in Michoacan. Smith
and Taylor (1950b:98) apparently accepted Gadow's statement and record
