argued, however, that these 2 taxa were conspecific, based on the discordant nature of the variation in the characters used to distinguish them, and maintained that position for a number of years (Wilson and Meyer, 1985;Wilson, 1988). Soon after the Wilson and Meyer (1969) review appeared, however, Smith (1971) opined that northern and southern populations were distinguishable on the basis of the presence of a loreal scale and a relatively high number of ventrals in the former (144-170), and the lack of this scale and the presence of a relatively low number of ventrals (111-134) in the latter. Smith concluded that these 2 groups should be recognized as subspecies. Savage (2002) accepted Smith's (1971) argument, but recognized the taxa sapperi and veliferum as separate species-level taxa, a position that has been followed by several other

In this study we reported new localities of the distribution of Frog Lithobates johni in Hidalgo, Mexico. These records are placed within the Sierra Madre Oriental and Gulf of Mexico. In addition, this note includes some general aspects of the natural history of the species, such as habitat and microhabitat when the species occurs.

Abstract:We record for the first time the recently described snake Geophis turbidus from the state of Hidalgo, Mexico. The species was recorded in cloud and pine forests, and this report extends the distribution of this species approximately 25 km from its previously known occurrence. In this paper, we also report the first description of a juvenile specimen, along with data on the natural history, morphology, and conservation of this species.

Herein we report 22 individuals of Xenosaurus newmanorum representing a new state record for Hidalgo, Mexico from the Municipality of Pisaflores. Previously, this species was known only from the Municipality of Xilitla in San Luis Potosí. These new records extend the distribution of this species 13.6 km south of its previously known occurrence. We also compare total body and tail lengths for the lizards in addition to cloacal temperatures and several measurements associated with microhabitat characteristics, which are equivalent at all three sites. That microhabitat congruence suggests that its preservation is critical for protecting X. newmanorum from population decline.
