104 PALEOZOIC PALEONTOLOGY. 
Locality 70 B.—Another locality where several species of fossils were 
secured from this formation is at the side of the river road, four miles 
northeast of Flatbrookville. The following species have been identi- 
fied from there: 
1. Zaphrentis sp. undet. 
2. Lingula sp. undet. 
3. Leptena rhomboidalis (Wilck 
4. Orthothetes pandora ( Bill.) 
5. Rhipidomella vanuxemi (Hall) 
6. Atrypa reticularis (1inn.) 
7. Spirifer sp. cf. S. varicosus Hall. 
8. Anoplotheca concava (Hall). 
. Platyceras sp. undet. 
Locality 89 B. —On the river bank, two miles northeast of Flat- 
brookville, the following species were collected from the Onondaga 
limestone : 
1. Orthothetes pandora (Bill.). 
2. Anoplotheca acutiplicata (Con.). 
Locality 88 B.—In an excavation in the lower, shaley beds of the 
Onondaga limestone, one-half mile northwest of Flatbrookville, on 
the river road, several imperfect specimens of Anoplotheca acutiplicata 
were collected. 
The entire recognized fauna of the Onondaga limestone in New 
so 
Jersey is a small one, and it does not afford sufficient characteristics 
for close correlation. There are none of the recognized species, how- 
ever, which do not commonly occur in the Onondaga limestone in 
its more typical localities in New York, and this, together with its 
stratigraphic relations, makes the correlation of the New Jersey for- 
mation under consideration reasonably sure. 
NEWFOUNDLAND GRIT. 
The Newfoundland grit is limited in its geographic distribution 
in New Jersey to the Green Pond mountain region. It is a heavy- 
bedded, fine-grained, light-colored, quartzite conglomerate below, be- 
coming a thinner-bedded sandstone above. It grades upward into the 
dark, siliceous, Monroe shales, without any line of demarkation. The 
total thickness of the formation is estimated as about 215 feet.
