A.C. BICKER 1957 APHODONTIA RURA POLKES FLAT, 5000 FT, 12 MI. NW HARP CAMP, SISKIYOU CO., CALIF. AUG. 28 I CATCHED ONE BETWEEN 3:00 PM & 10:00 PM IN BURROW SYSTEM ON DRY HILLSIDE ABOUT 25 YDS FROM A SMALL SWIFT STREAM. MUCH DIRT & ROCKS LING OUTSIDE OF BUNROWS AND THIS MORNING WAS DRY. HOLES WERE ABOUT 3-4 IN IN DIAMETER. TAIL WAS #1 STRONG, BUT HAS BEEN FINNED IN TWICE DURING PRECEDING DAY & NIGHT. NEAR REST. TAILS LEFT ANOTHER 24 HOURS BUT NO MORE WERE CAUGHT IN THIS RUN. SAW SIMILAR HOLES 50 YDS DOWN HILLSIDE IN MORE OPEN HABITAT, SCHUTLESS SET THERE WERE NOT SPRUNG. I GOT WHERE APHODONTIA WAS TRAPPED HAD CONIFERS & DEAD LOG & BRUSH AROUND IT AND LITTLE GREEN GRASS OR PLANTS. TAIL MEASUREMENT WAS TAKEN FROM EARS AFTER SKINNING, BEFORE SKINNING TAIL SEEMS TO HAVE BEEN MUCH SHORTER.
