18 Oct 1954 Calif: Alameda Co, Berkeley plans call for an examination of the roads, during the fall and winter rains, in the vicinity of the valley including the towns of Concord, Walnut Creek, Danville, Alamo and San Ramon. It is known at the present time that Toricha occurs within one mile SW of Walnut Creek but presumably nowhere E the main N-S highway (Calif. State Hwy #21). None is known from the Mt. Diablo area. Ambleytoma is known from Luni, NE of Walnut Creek and from Concord, but nowhere presumably W the N-S. highway. It is this apparent non-overlapping contact between the two genera which will be investigated during this rainy season. The area to be included extends from the Bay on the north to Dublin on the south, and areas as for east and west of this line as seem appropriate. On this date, or perhaps early on the morning of 19 Oct, a light rain fell, measured in Berkeley as 0.1 inch. This is first rain of the fall season. 19 Oct Calif: Contra Costa Co, Canyon Stebbins examined road between town of Canyon and Pindurst intersection. He reports 55% of road wet with condensation and 15 Toricha counted, several Ensatina and Oreides. No additional rain was occurred.
