Vars, along the railroad, and then a third of a mile northward 
along a country road, it is found in the Proetus zone. Small speci- 
mens occur in the Proetus zone also a mile northwest of Hawthorne 
station, along the railroad. It occurs also over a mile west of 
Edwards station, along a creek southeast of a church on the 
Ottawa pike, associated with the following fossils: columnals 
usually referred to Heterocrinus and Glyptocrinus, Pholidops sub- 
truncata, Dalmanella, Hebertella, Plectambonites, Zygospira modesta, 
Byssonychia radiata, Cornulites, and Acidaspis. Mr. W. R. Bil- 
lings showed me a Catazyga headi said to have been obtained here. 
Going from Vars about three-quarters of a mile westward, and 
then a quarter of a mile southward to a point where the road 
crosses a small stream, Pterinea demissa is found at a horizon 
provisionally regarded as Richmond, owing to the presence of the 
Richmond form of Strophomena fluctuosa. The remainder of the 
fauna consists of the following species: Pholidops subtruncatay 
Crania. Lingula, Rafinesquina alternata of flat form and fully 30 
mm. in length, Plectambonites, Catazyga headi, Zygospira modesta, 
Clidophorus resembling praevolutus, Byssonychia radiata, Modio- 
lopsis belonging to concentrica group, Whiteavesia pholadiformis, 
Rhytimya, Lophospira belonging to bowdeni group, Cornulites 
both attached and curved, and also straight and free, Orthoceras, 
Bythocypris cylindrica, Calymene, and Isotelus. 
A third of a mile south of the Strophomena fluctuosa locality 
there is a cross road, near which, a short distance westward, a 
farm lane, formerly an open road, turns off southwards, and about 
half a mile down the lane reaches the highest fossiliferous strata 
of the Richmond, directly beneath the Queenstown shales. Resi- 
dual blocks here contain Pterinea demissa associated with Byssony- 
chia radiata, Hebertella resembling occidentalis, and numerous 
specimens of a Zygospira resembling kentuckiensis. 
In the Cincinnatian areas of Ohio, Indiana, and Kentucky, 
Pterinea demissa also is much more common in the Richmond than 
in the Maysville. It appears absent in the Eden, but similar 
specimens occur in the Greendale and Rogers Gap divisions of 
the Cynthiana formation in Central Kentucky. 
For Pterinea demissa, as identified from the lower Richmond 
strata of Ohio, the generic term Caritodens was proposed by the 
writer. 2 These Ohio specimens retained only the thin outer layer
