Hylo regilla (Tree toad) Mayhew 1947 May 10 Wildcat Canyon, Contra Costa Co., Calif. 2 specimens were found along a little stream just south of Tilden Park golf course clubhouse. One was grunit-yellow + blended in perfectly with the little stick on which he was sitting about 2" from the water. His body temperature was 14° C, the water temp. was 12.7° C., air temp. was 16° C. He was sitting below an alder tree right at the edge of the stream. The other specimen was bright green. Horsetails were the commonest plants around the area where these 2 were found. Both were M, which could be told by the dark gular patches. After being in captivity for a few minutes, one was a bright green in color, the other was a dark brownish-green. The mask through the eye was prominent in both specimens. The gular pouch was rather folded - it is used in making croaking sounds. Two egg capsules were found attached to a stick close to the shore of a small pool about 8' in diameter. One capsule was broken over, but the other one still contained eggs. The capsules were gelatinous in nature, about 1" in diameters. Each egg was contained in its own separate capsule within the large capsule. The stick was about 2" below the surface. The temperature of the water was 12.5° C.
