We found one Anides lugubris, three A. flavipunctatus, four Ensatina and several Batrachoseps. From the Stevenson Home we went to a ranch ("Montesol") 3 1/2 mi E 1/2 mi S Mt. St. Helena where the presence of numerous aquatic triturus had been reported. The Triturus were present in artificial, spring fed pools some of which also contained trout. 24 Triturus were taken.
