During the months of June and July, 1951, a field party from the University of Texas collected amphibians and reptiles from the Black Gap Area (29 degrees 30 minutes to 29 degrees 40 minutes N.-102 degrees 50 minutes to 103 degrees W.), Brewster County, Texas. The area under study was divided into five general habitat types: the streambed, floodplain and pond, limestone slope, igneous slope and canyon and cliff. The tabulated summation of this habitat data clearly showed species preferences. A total of 452 specimens were taken including 114 frogs and toads of four genera, 263 lizards of eight genera, 74 snakes of ten genera and 3 turtles of one genus. A slight eastward range extension is noted for Sonora semiannulata blanchardi.
