Even with the abundance of material the assignment of a specific name to these anoles is only tentative, for definite determination between _Anolis nebulosus_ Wiegmann and _A. nebuloides_ Bocourt is uncertain. Bocourt (1873:75) distinguished _A. nebuloides_ from _A. nebulosus_ by the following characters: (1) head scales keeled, not smooth; (2) snout narrower; (3) ear opening larger; (4) supraorbital semicircles separated by a row of small scales and not in contact; (5) dorsal scales larger and subequal in size to the belly scales. Boulenger (1885:77) used the same characters; Smith and Taylor (1950b:58) in their key to the Mexican species of _Anolis_ stated that the dorsal scales are slightly smaller than the ventrals in _A. nebulosus_ and markedly smaller in _A. nebuloides_. Smith (_in litt._) stated that the characters of the relative sizes of the dorsal and ventral scales were incorrect in that key. The application of the above criteria to specimens from Michoacán has not resulted in the recognition of two species. The majority of the specimens have the supraorbital semicircles separated by at least one small scale; the head scales, with the exception of those on the snout in a few individuals, are smooth; the dorsal scales are only slightly smaller than the ventrals. In other characters of scutellation the specimens are highly variable. The males in life have an orange throat fan. Anoles of this kind have been found in Michoacán, Colima, Jalisco, Nayarit, and southern Sinaloa. Near Oaxaca, Oaxaca, specimens were collected that superficially resemble those from Michoacán and farther north. These have low keels on the snout scales, dorsals somewhat larger than the ventrals, and a pink throat fan. In ten males from Oaxaca the size of the dorsal scales relative to that of the ventrals is 1.00:0.83; the same ratio for 25 males from Michoacán is 1.00:1.08. In both samples there are specimens in which the dorsal and ventral scales are about equal in size.
