J. B. Richardson 934 2 Yellow-legged Frog Apr 22 Emerald Lake, 9340 ft. Trabuco Co., California Two specimens were collected from immediate vicinity. A number of these frogs have been seen about the rain pools and small lakes that do not contain fish. They can be found in all stages of development. Jun 24 Emerald Lake, 9340 ft. Trabuco Co., California A specimen taken from a small rain pool 100 yds below the lake. The pool was 6' x 2' and about 4" at its deepest part. Jul 16 Quaking Aspen Meadow, 7500 ft. Trabuco Co., California. Four specimens taken from the little stream that runs through the meadow. They are plentiful in the stream but not numerous; I should judge that there is one individual every 100 ft of stream.
