64 TOPOGRAPHIC DEVELOPMENT OF KLAMATH MOUNTAINS, [bull. 196 
Mr. Hershey submitted some fossils from Pattersons, on New River, 
which Dr. Girty regards as belonging to the Carboniferous on account 
of their relation to other and more characteristic fossils found in the 
Hay Fork region. They are in line with a portion of considerable 
collections made for the writer last spring in Trinity County by Mr. 
James Storrs. A belt of lenticular limestone masses having the same 
general northwest-southeast strike is well exposed a few miles east of 
Hay Fork, and has been traced for many miles, stretching more or 
less continuously from near Knob- post-office to Pattersons. Fossils 
were collected at five points along this line, and concerning them Dr. 
Girty remarks that ' ' the fauna is characterized by the presence of 
Fusulina and strongty indicates the geological horizon to be Upper 
Carboniferous. Besides' a number of corals, there is a pentagonal 
crinoid stem suggestive of Pantacrinus, and a small organism, prob- 
ably an alga, which occurs in nearly all the localities and is very 
abundant a few miles southeast of the village of Hay Fork." 
Another belt of limestone, the exposures of which are more or less 
interrupted, has been traced by Mr. Storrs from North Yallo Bally to 
Hj^ampom along the eastern slope of the South Fork of Trinity River 
in Humboldt County. These have yielded fossils at a number of 
points, among which corals, Pentacrinus 9, an echinoid, and two gas- 
teropods have been recognized, but not identified specifically, by 
Dr. Stanton, who refers them, apparent^ with some doubt, to the 
Juratrias. 
In the region of Shasta County, extending north and northeast from 
French Gulch, as far at least as Slatonis, there is a great development 
of dark slates in which occur local conglomerates. Mr. Storrs col- 
lected a large number of fossils, and most of them were obtained from 
small masses of limestone in the conglomerates. These were referred 
to Mr. Charles Schuchert, of the National Museum, who reports as' 
follows : 
Localities Nos. 5971 [between Tower House and French Gulch], 4, 7. 10, 11, 13, 
15, 29, 30, and 31 [on Sacramento River, between Morley and Portuguese Flat] 
represent one conglomerate horizon. It contains limestone pebbles, sometimes of 
considerable size, and these were derived from a Middle Devonian formation, 
apparently the same as that near Kennett, Shasta County. The common forms 
are Fistulipora, Cladopora, Favosites (two or more species, one of which is F. 
canadensis), Cyathophyllum, and Syringopora. All of these species are also 
known in the Middle Devonian limestone near Kennett. 
These fossils, however, do not indicate the age of this conglomerate, more than 
that it is not older than Middle Devonian time. It was deposited subsequent to 
the Kennett limestone, and there are no fossils either in the pebbles or in ti.il 
paste (there are some free fossils in the paste, but these are fragments of the same 
species as those in the pebbles) , younger than those mentioned above to more 
definitely fix the age of this conglomerate. 
Locality No. 2 [on Sacramento River, one-third mile above Morley] is a shaly 
limestone in place. This bed is not represented in our former collections from 
the Shasta County Devonian. It abounds in Atrypa missouriensis Miller (one of
