Trivurns White Rock Ranger Station, 4800 ft, Trinity Co., Calif. June 1, 1946 Visited a pond about which Ward Russell had told me the previous day. He mentioned having seen Triturus lying on the bottom of the pond near the shore. I used a small hand net to collect the specimens. The Triturus were seen lying on the fine dark silt, from 6" to 10 ft from the pond's edge, in water from 2" to about 6 ft. deep. The dark dorsal coloration blended in well with the substrate, although the substrate in some cases was considerably lighter than the dorsal coloration. The larger individuals tended to stay farther off shore, and in deeper water. The one large adult taken was quite smooth. Of the remainder, a few are in the process of losing their rugosity, but the great majority are still hard and granular. The animals seemed rather sluggish, and if alarmed crawled slowly along the bottom a few feet, and then stopped. A few swam away rather rapidly, a few inches from the bottom, their undulatory motions carrying them swiftly away. Several individuals were seen to burrow into the silt, which was exceedingly fine and at least 4 feet deep. This burrowing was apparently accomplished by the same movements used in swimming.
