In Michoacán _Anolis nebulosus_ occurs from sea level to elevations slightly in excess of 2100 meters, usually in areas of dense cover, whether this be herbaceous, viney, or woody, ordinarily on the ground as well as in bushes and trees. One was in a bromeliad growing about ten meters above the ground. In the arid Tepalcatepec Valley anoles of this species are most frequently found in the tangled growth along streams. Above Uruapan they were found in pine-oak forest, and on the Mexican Plateau between Zamora and Zacapu they were found in a bunch grass-scrub oak association. ~Anolis schmidti~ Smith _Anolis schmidti_ Smith, Publ. Field Mus. Nat. Hist., zool. ser., 24:21, January 30, 1939.--Manzanillo, Colima, México. La Placita; San Juan de Lima. Peters (1954:11) reported on the specimen from La Placita; another was secured at San Juan de Lima in 1956. The latter (UMMZ 115078) is a male having a snout-vent length of 43.0 mm. and a tail length of 70.5 mm. The dorsal ground color is pale tan; there are five pairs of irregular dark brown dorsolateral blotches. In life the throat fan was pale orange. These specimens agree with those from Colima described by Duellman (1958c:10). The distribution of _Anolis schmidti_ seems to be restricted to the coastal lowlands from Michoacán to Nayarit. ~Basiliscus vittatus~ Wiegmann _Basiliscus vittatus_ Wiegmann, Isis von Oken, 21:373, 1828.--México. Type locality restricted to Veracruz, Veracruz, México, by Smith and Taylor (1950b:72). Apatzingán (9); Capirio; Coahuayana (5); El Cerrito; El Sabino (2); El Ticuiz; La Placita (3); Maruata (2); Motín del Oro; Ostula; Playa Azul (3). This species has been found only on the coast and in the low Tepalcatepec Valley. In the latter area it is restricted to riparian situations along the larger streams. The lizard is abundant in the mangrove swamps bordering the brackish lagoons on the coast. In July, 1955, scores of individuals were seen around Estero Pichi at Playa Azul. Adults, especially the large males, are exceedingly wary and difficult to collect. At all localities where they were found, the lizards were most often seen in dense bushes, where they are well camouflaged. Individuals of all sizes were observed to run across the surface of the ponds. ~Iguana iguana rhinolopha~ Wiegmann _Iguana rhinolopha_ Wiegmann, Herpetologia Mexicana, p. 44, 1834.--México. Type locality restricted to Córdoba, Veracruz, México, by Smith and Taylor (1950b:72). _Iguana iguana rhinolopha_, Van Denburgh, Proc. Acad. Nat. Sci. Philadelphia, 1897:461, January 18, 1898. Apatzingán (8); Capirio (3); El Cerrito; El Ticuiz (2); La Placita; La Playa (2); Maruata; Playa Azul; Río Cachán.
