Rana E slope Joe Escamilla, 7300', Dep't. Chalatenango, El Salvador March 20, 1942 Stinton and I hunted amphibia along a small stream near camp. This flows at the bottom of a steep-walled draw, and runs north. The canyon walls have been stripped of fo- rest and planted to wheat. Along the stream banks there is fairly heavy vegetation of blackberry bushes, ferns, & a variety of low shrubs and bushes.

There was a heavy fern growth on one bank, the plants hanging over the water providing shade. The other bank was of open gravel & rock. The bottom was of fine silt over gravel, with fallen leaves lying over the silt. This frog dove into the water and disappeared beneath the overhanging ferns, which we tore away.
