Absence of One Eye in a Frog

Abstract

All of the above specimens were captured alive. Had we been provided with a collecting pistol, we might have collected many more specimens of the two small species of Sceloporus and Holbrookia texana. The Marnock hill is very rocky and in many places is covered by growths of cedar, scrubby deciduous trees and shrubs, opuntias, and other flora. A number of goats get most of their subsistence on its slopes and summit and it is surprising that it is still inhabited by so many species of small native animals. In the sheep regions in western Texas, the wooly grazers have destroyed much of the smaller fauna through retarding the growth of vegetation, and killing snails and reptiles with their hoofs. Along Helotes Creek, I have at different times collected or noticed specimens of Eumeces brevilineatus Cope, Sceloporus spinosus floridanius Baird, Leiolepisma laterale Say, Cnemidophorus sexlineatus gularis Baird and Girard, Natrix sipedon transversa Hallowell, Natrix rhombifera Hallowell, Storeria dekayi Holbrook, Thamnophis proximus Say, Pseudacris ornata Holbrook, Acris gryllus Le Conte, Rana catesbeiana Shaw, R. pipiens Schreber, at least two large species of Bufo, and other species which I do not now recall. Water turtles are numerous in the creek. Considering the nearness of the large and populous city of San Antonio, the fauna of the Helotes neighborhood, as regards number of species, seems singularly undisturbed by the flight of the past forty years.
