Smith and Taylor (1948:93-4) listed specimens of this species from Organos and El Treinta, Guerrero, and from Paso del Río, Quesería, Santiago, and Tecomán, Colima. The species occurs from Sinaloa and central Veracruz southward at low elevations to the Isthmus of Tehuantepec and thence along the Pacific lowlands into Central America. Almost certainly it occurs on the coastal lowlands in Michoacán. Since the amphibian fauna of the Tepalcatepec Valley has been better sampled than that of the coast, I suspect that if Gastrophryne occurred in the Tepalcatepec Valley, I would have found it there.

Lepidochelys olivacea (Eschscholtz)

Chelonia olivacea Eschscholtz, Zool. Atlas, pt. 1, p. 2, 1829.—Manila Bay, Philippine Islands.

Lepidochelys olivacea, Girard, United States Exploring Expedition..., vol. 20, Herpetology, p. 435, 1858.

According to Smith and Taylor (1950b: 15), this sea turtle is known from the entire Pacific coast of México; these authors reported the species from Chiapas, Oaxaca, Guerrero, Colima, and Sonora. Although the only sea turtle that I observed in Michoacán is Chelonia mydas, others probably do use the sheltered beaches for nesting. The scanty records of sea turtles along the Pacific coast of México indicate that Chelonia mydas and Lepidochelys olivacea are the most abundant species in that region. There are scattered records of Dermochelys coriacea, Caretta caretta, and Eretmochelys imbricata along the Pacific coast. The occurrence of any of these along the coast of Michoacán is probable.

Geoemyda pulcherrima pulcherrima (Gray)

Emys pulcherrima Gray, Catalogue of the Shield Reptiles in British Museum, vol. 1, p. 25.—México. Type locality restricted to Presidio de Mazatlán, Sinaloa, México, by Smith and Taylor (1950b:30).

Geoemyda pulcherrima pulcherrima, Wettstein, Sitzb. Akad. Wiss. Wien, 143:18, 1934.

Smith and Taylor (1950b:30) recorded this species from Sonora, Sinaloa, Nayarit, Colima, and Guerrero; these records indicate that the species probably is distributed along the Pacific coast of México southward from southern Sonora. It unquestionably occurs on the coast of Michoacán. Natives of the coastal lowlands tell of another "tortuga de la tierra" besides Geoemyda rubida. In the collections of the Museum of Natural History of the University of Illinois is a specimen of Geoemyda pulcherrima from Mexcala in the Balsas Basin in northern Guerrero. On the basis of this specimen it is highly probable that the species also inhabits the Balsas-Tepalcatepec Basin in Michoacán.
