Of these four members, so wel] and werden sid ot developed in 
Cuyahoga County, only the last uniform rmly r s its typica 
character in Central and Southern Ohio. It is saya & a black 
bituminous shale containing scales, spines and teeth of fishes, and 
shells of a small species of Zingula. Not only is it uniform, but 
it is unique, both in respect to its fossils and its litholowical 
characters. In the latter particular, it is true, it closely resem- 
bles s the Huron shale (Devonian). But the two never exist together

the Erie shale (Chemung) ; on the Ohio River Wy 147 feet of shales 
and sandstones of the Lower Waverly ; and in Central Ohio by 75 
to 100 feet of shales, pected limestone and sandstone.

6. Jurassic fossils in the Coast Range of British Columbia. 
—Mr. J. F. Whiteaves vig described the Jurassic fossils collected 
by Mr. G. M. niga mostly from the vicinity of Iltasyouco 
River, a tributa £S alacon River, and Sigutlat Lake. The 
author concludes that nine of the twenty-eight species are identi- 
cal with those of Jurassic rocks of Dakota described by Meek, 
pee & Gryphea calceola var. Nebrascensis, Camptonectes ex- 
uatus, Humicrotis curta, Modiola  ( Volselta) formosa, M. per- 
picts Gram natodon inornatus, Astarte fragilis, Pleur uromya 
subelliptica, Planorbis veternus. The other species include Lima 
duplicata “boweeh , Stephanoceras Humphreysianum Sowerby, 
omya unioi les Remer, Astarte ventricosa Meek, a species 
described from Jurassic rocks 0 f Nevada, Trigonia Dawsonit _ 
Whiteaves, also identical with a eves species, a Belemnites, ue. 
The species are stated to be probably either Liassic = sower 
Oolite. Mr. Whiteaves remarks that’ the Upper
