Bufo boreas Aug. 16, 1960 Squaw Meadows, Squaw Vally, 6200 ft., Placer Co., Calif. - A Bufo was taken in a rather shallow pond in the area where a Rana (#23) was taken. The pond was 4 x 6 feet in size, about a foot deep, and the bottom was largely covered with silt. There were a few small fish in the pond, but not much other evidence of life. The animal was frightened from the gravel at the north side of the pool, which sloped at about a 45° angel to the bottom of the pool. The toad swam about three feet to a rock at the east end of the pool/ (down stream) where it was captured. See account of Rana muscosa for more details of site. #27. Snout-vent length about 1¾ inches. Ground color dark brownish olive with a narrow pale yellow line from the frontal region to the rump; a roughly symmetrical (left-right) pattern of dark brown tubercles and warts, bordered with black and then narrowly with pale yellow. Head with a dark brown bar on the middle of the eyelids extending transversely to the pale median line and a similar, but smaller one on the anterior part of the interorbital area. Side of head pale yellow- white, with a dark brown, black-bordered, square blotch below the anterior part of the eye and another narrow diagonal bar behind this, the area between these bars and the side of the snout suffused with darker. Venter dirty white, belly heavily black spotted, rump grayish brown, under side of limbs grayish-white, black spotted; feet blackish, tubercles dull golden.
