P. Zwickel Mar. 29, 1952 Hypsiglena torquata muchulata 147 2 mi. NW Calistoga, Napa Co., Calif. 1738 R2 Found in the middle of a rotten digger pine log, elevation 610', on a ridge at the north end of Napa Valley. This is in the area where the digger pine & Douglas tire meet without benefit of a yellow pine buffer zone. The exact location is on a grassy slope beside a black oak or an oak, digger pine and monzantia studded hillside. About 1/4 mile down the ridge there is a homesite surrounded by douglas fire and oaks, probably indicative of the natural vegetation of this ridge. There is a single scraggly doug fir 200 yards up the ridge from the snake locality, in the midst of the digger pine and oak. On the same 10' x 1' log which held the Hypsiglena were no Diadophis, 3 Ancistrus laevis and a small Herkasta multicarinata. Dozens of Ancistrus flavipunctatus were taken from ad- jacent logs. Dorsal ground color: Drab (Redgwing) Neck band close to Mummy Brown Dorsal blotches close to Olive Brown.
