J. Rodriguez - 1941 Dicamptodon ensatus Sept. 15 Mus. Vert Zool. Univ. Calif., Berkeley, Alameda Co., Calif. Color record, from Ridgway, of Dicamptodon no. 35484, collected near Stephens Camp, Waddell Creek, Santa Cruz Co., Calif., Sept. 14, 1941. Dark parts of mottling, Mars Brown (Pl. XV, 13, k); light parts, Verona Brown (Pl. XX) x, 13'' k). As I took this salamander in my hand and held it while comparing it with my it started emitting mate, from its vent. It continued for about one minute, letting up somewhat twice, but increasing the rate of emission after each let-up. All together, it must have emitted 10 cc. or more. This is the first time I have seen this reaction in a salamander.
