pecimens have been referred to _Phyllodactylus homolepidurus_ by
James R. Dixon (_in litt._), who is currently studying the American
members of the genus. Geckos of this species have been found in tropical
semi-deciduous forest in the coastal lowlands to elevations of 500
meters. Most specimens were found beneath the bark of standing dead
trees or stumps. Two individuals from El Ticuiz (UMMZ 115102) in life
were dark gray above with brownish tubercles; the belly was a dusty
cream-color. Apparently this species does not enter the Tepalcatepec
Valley, where _Phyllodactylus lanei_ is abundant.

~Phyllodactylus lanei~ Smith

_Phyllodactylus lanei_ Smith, Univ. Kansas Sci. Bull.,
22:125, November 15, 1935.--Tierra Colorado, Guerrero,
Mexico.

Apatzingan (13); 21 km. S of Arteaga: El Sabino (53); La
Playa; Ostula (2); Rio Marquez, 10 km. S of Lombardia (8);
16 km. N of Tafetan.

This widespread species has been taken at elevations of less than 1100
meters in the Balsas-Tepalcatepec Basin, where it occurs in riparian
situations in the foothills. Specimens have been collected in tropical
semi-deciduous forest at Ostula and in oak forest south of Arteaga; both
of these localities are on the Pacific slopes of the Sierra de
Coalcoman, a region inhabited by _Phyllodactylus homolepidurus_. Both
species have been collected at Ostula.

A juvenile from 21 kilometers south of Arteaga (UMMZ 118933) had
alternating black and white bands on the tail. In life most of the
lizards are dull ashy gray or grayish tan above and white below.
According to Dixon (_in litt._), one specimen from Apatzingan (UMMZ
115102) resembles _Phyllodactylus magnus_ in scutellation, but it lacks
the distinctive yellow venter of that species.

Apparently _Phyllodactylus lanei_ is restricted to rather mesic
environments in the Balsas-Tepalcatepec Valley and surrounding
foothills; in the more open arid environments on the floor of the valley
it seems to be replaced by _Phyllodactylus duellmani_.

_Phyllodactylus paucituberculatus_ Dixon, Southwest. Nat.,
5:40, April 15, 1960.--Rio Cupatitzio (= Rio Marquez), 6.5
miles south of Lombardia, Michoacan, Mexico.

Rio Marquez, 10 km. S of Lombardia (6).

Two of these specimens (UMMZ 112692-3) were discussed in detail by Dixon
(1960:40) in his description of the species. On August 25, 1960, Dixon
collected four additi
