STRATIGRAPHY OF CALIFORNIA COAST RANGES. 427 
found together in that portion of the state, and their relation to 
each other was more or less a matter of inference. The contact 
which has just been found is on the Eagle Ranch in the Santa 
Lucia Range. The central portion of the range is there formed 
of Knoxville shales and sandstone carrying Azcel/la, the total 
width exposed being about three miles. The Knoxville is 
bordered on the west by a great dike of serpentine, while on the 
east a nearly hidden axis belonging to the Golden Gate series 
projects through it in numerous places. The Knoxville presents 
a very much disturbed condition, partly due to the dikes of 
serpentine. The Chico, consisting almost wholly of heavy- 
bedded sandstone, rises on the eastern slope, overlapping the 
Knoxville shales and capping portions of the first line of hills. 
It has not undergone the same amount of disturbance as the 
Knoxville and is nowhere folded in with it, appearing rather as a 
thin capping on an irregularly eroded surface. Fossils were 
sought for a long time in the sandstone without any result. 
Finally a number of poorly preserved specimens were obtained 
from the summit of a hill about one mile south of the Ranch 
House. The following is the list: Bacultes chicoensis, Trask. 
Trigonia evansana (?),Meek. Pectunculus veatchi, Gabb, Cucul- 
laea sp., Pentacrinus sp. Ina small ravine near the spot where 
the fossils were obtained there is a contact between the sandstone 
and the dark shales. This ravine extends up the west side of 
the hill making a slight depression nearly to its summit. The 
northern portion of the hill is capped with a thin layer of 
the Chico sandstone, dipping south at an angle of 30°. The 
sandstone extends to the bed of the ravine and is there 
exposed resting on the shales. The latter are well shown, not 
only underneath the sandstone but also on the slope of the hill 
south into which the dip of the sandstones would carry them. 
The sandstone has a very regular bedding while the shale under- 
neath is so broken that the stratification is not distinctly visible. 
The spot was examined particularly with reference to the pos- 
sibility of the phenomena being due to faulting, but no evidence 
of it could be discovered. Fossils were not found in the Knox-
