Davis. 1941. 3 Monte Cristo mine, Zoo, Dep't Morazan, El Salvador. Nov. 30, 1941. are often found on the brush fences erected by the natives. The Divisadero road is very dusty and runs between cultivated fields for the most part. Took a Cnemidophorus (894) on a dry open bank by the roadside. The acacia-grown pastures near Divisadero were unproductive. Went along a road running north from Di- visadero. Saw a large adult Benosaura in the grass by the roadside. It disappeared down a hole about 6 inches across, perfectly round and smooth, and running absolutely straight down at least 6 feet. I could not touch bottom with a stick at least 6 feet long. Found a snake lying dead in the road, too far gone to collect. On my return to camp found that Hildebrand had collected a worm-snake (M.H.809) found at the corner of the hut. Dec. 1, 1941. Leitz took Paley, Hildebrand, and I over to the Barrio mine, 3 mi. W. of the Monte Cristo mine, to hunt iguanas. He shot a Herpobolius cachimans which I skeletonized. I took 2 young Benosaura from a brush fence surrounding a cornfield. Went down to a stream, the Rio Grande, where Leitz shot two iguanas. See species notes for this date.
