CRETACEOUS BEDS OF ROGUE RIVER VALLEY. 459 
Ashland locality —About four miles south of Ashland, near the 
railway, the following species have been collected: 
Pachydiscus aff. denisonianum, Stol. Cucullea truncata, Gabb. 
Cinulia obliqua, Gabb. Chione varians, Gabb. 
Fasciolaria rigida, Bailey. Cyprimeria lens, Gabb. 
Gyrodes pansus, Stol. Homomya concentrica, Gabb. 
Pugnellus manubriatus, Gabb. 
This indicates an upper horizon for these beds, but not the 
uppermost Chico. The beds here are of a grayish, or light-col- 
ored sandstone, dipping toward the east at an angle of about 30°. 
A short distance to the south, where the sandstone is quarried on 
the east side of the railway, the beds are thicker and of a light 
grayish color; they also dip toward the east at about the same 
angle. 
Griffin Creek.—Collections made at a second locality on Griffin 
Creek. a few miles east of Jacksonville, contain the following 
Species: 
Trigonia leana, Gabb. Exogyra, sp. 
T. tryoniana, Gabb (?). Inoceramus, sp. 
Here the beds are of a tawny or grayish sandstone, and dip at 
an angle of 20° toward the west and northwest. ‘These strata, 
as at Jacksonville, a few miles to the west, rest upon the highly 
tilted or folded auriferous slates. The fossils indicate a horizon 
a very little lower than the beds near Ashland. 
'49-Mines.—A third locality, at which the largest and most 
interesting collection was made, is one and one-half miles south- 
west of the town of Phcenix, at the old placer mines, locally 
known as the ’49-Mines. Here also the Cretaceous beds consist 
of conglomerates, yellow shales, and sandstones, resting upon 
the auriferous slates and dipping toward the northeast at an 
angle of 30°. The fossils collected at this point show these beds 
to be somewhat lower than those before mentioned, although 
some of the fossils belong to the upper Chico of the California 
Cretaceous. The following is a list of the fossils identified from 
this locality :
