Seib, R. 1981 Berkeley to Corral Hollow, San Joaquin Co., California 2 June I and four 107 T.A.'s drive 5 station-wagons to Corral Hollow at 4:30 PM. I left first with 5 students and arrived 5:30pm at Mines Road. See log on back page for milages. Saw about 20 snakes, mostly dead Pituophis, but four live Crotalus and a dead Coluber constrictor. All snakes were kept on ice and killed right away to maintain stomach contents. I take head and body measurements off of freshly killed snakes prior to preservation. Berkeley to Corral Hollow, San Joaquin Co., California 4 June Tonight was much warmer, ~85°F. We saw fewer snakes, no road kills, but greater diversity. I caught a Rhinocheilus lecontei which discharged an large amount of blood from its cloach so that I thought it was a D.O.R. Also seen were hae Arizona (1 adult), Lampropeltis (1 large adult), Pituophis (2), Crotalus (1adult, 1 baby).
