R. Zweifel
Arroyo Mochos, Alameda Co., Calif.
Feb. 7
Looked for Rana boylii. A few juveniles out, but not very scare. Captured one adult & water 10.8° C., in the upper Arroyo. Juveniles in water 8.8-9.2° C.
Warm & sunny today & has been so for last week. Two weeks ago there was a 6" snowfall in the upper part of the Arroyo.
I found one adult Eunectes gillberti beneath a board, Jerry Cook and Dick Russell two others. Also a small Tammyspeltes gelatinus.
