(948 D. P. PEARSON 33 journal Sulbury Caves, 11 mi. SE Hat Creek, Shasta Co., Calif. Nov. 6 Left Berkeley supper time yesterday with aunt + Carol. Drove up q.q. W. to about 15 mi. S of Red Bluff. Camped in field about 10 p.m. where the first rodness starts. I had the good fortune to sleep a few yards from some burrowing owl holes. Just at daybreak 3 or more owls returned to these holes.

The holes were dogger-size on top of a mound. Some had white droppings, and feathers in them, two had a pellet. One was red-colored containing insect remains, the other mammal but no skull. Left about 8 a.m. and arrived at Sulbury caves at lunch time. They are two caves (in reality one with an opening in the middle) accessible through a large creter. They are smooth clean tunnels, branched, looking like man-made tunnels big enough for a motor car, quite dry. 8 or 9 corycorhinus were hanging singly and conspicuously, widely spaced, from the ceiling. Two or three Eptteressa were seen in one cove but could not be dragged onto Caught 6 females and 3 males (random catch) and removed them. Then went hunting for other caves. Found two on the Rim Rock Road about a mile south of here. One was low-ceilinged, beset with moisture, had icel stalgwater but no bats. The other had 3 ? Coryphalin which I took. It was a dry cave similar to Sulbury but
