FORMATIONS OF DEVONIAN AGE. 107 
Locality 188 A.—Near the roadside at Sylvester’s Corners, Wood- 
‘stock, five and one-half miles southwest of Newfoundland, the follow- 
ing species were collected: 
1. Fenestella? sp. undet. 
2. Chonetes sp. undet. 
3. Camarotechia sp. undet. 
4. Homalonotus dekayi (Green).? 
Although the entire known fauna of the Monroe shales, as indicated 
in the foregoing lists, is not a large one, its characteristics are un- 
doubtedly those of the Hamilton fauna of the New York section. 
Tropidoleptus carinatus is one of the most characteristic Hamilton 
species, and its identification in New Jersey can be made without 
the least doubt. All of the other species recognized are also Hamilton 
forms, with the exception of Anoplotheca acutiplicata and Dalmanites 
anchiops, which have been originally described from the fauna of 
the Onondaga limestone. 
BELLVALE FLAGS. 
This formation is scarcely more than a continuation of the last. 
The beds are more arenaceous, but there is a gradual gradation from 
the shale beds below into the dark-colored grits and flagstones. The 
average thickness of the formation is about 1,800 feet. 
Locality 144 A.—Fossils do not commonly occur in the Bellvale 
flags, but from the material which has been excavated to form the 
outlet of the Oak Ridge reservoir, near Newfoundland, the following 
species have been collected: 
. Crinoid stems. 
. Tropidoleptus carinatus (Con.). 
. Spirifer audaculus (Con).? 
. Paleoneilo emarginata (Con.). 
. Paracyclus elliptica Hall. ? 
Grammysia sp. undet. 
. Cyrtonella mitella Hall. 
. Strophostylus sp. undet. 
These species constitute the known fauna of the Bellvale leeae in 
New Jersey. They are all Hamilton forms, with none of the char- 
acteristic Chemung species of the New York faunas.
