Zone 96 of Gulf Brook section (H55 A). — This zone, comprising 
1 foot of fossiliferous sandstone, contains the following faunule: 
Faunule of zone 96 of Gulf Brook section (1455 A) . 
[a, abundant; c, common; r, rare.] 
1. Aulopora sp. (r). 
2. Orthothetes chemungensis (a). 
3. Atrypa spinosa (r). 
4. Spirifer disjunctus (c). 
5. Leptodesma sp. (r). 
This is the highest fossiliferous zone of the section. The beds 
following it, which extend to the lower end of the gorge, appear to 
be entirely barren. 
GRANVILLE CENTER SECTION. 
Bv H. S. Williams. 
One-half mile south of Granville Center 35 or 40 feet of gray, sandy 
shales and sandstone outcrop near the brow of the hill just west of the 
highway. This outcrop lies near the axis of the anticline and shows 
no dip. This locality is about 2 miles north of the Gulf Brook sec- 
tion, and the beds represent a horizon somewhere near the base of 
that section. The faunule which they contain includes the following 
species: 
Faunule of Granville Center section (1455 B). 
[a, abundant; c, common; r, rare.] 
1. Stropheodonta (Douvillina) mucro- 
nata (r). 
2. Chonetes scitulus (a). 
3. Productella speciosa (r). 
4. Dalmanella tioga (c). 
5. Leiorhynchus sinuatum (c). 
6. Cryptonella sp. (c). 
7. Atrypa aspera (c). 
8. A. reticularis (c). 
9. Spirifer mesistrialis (r). 
10. Delthyris mesicostalis (a) . 
11. Ambocoelia gregaria (c). 
12. Edmondia philipi (r). 
13. E. subovata (r). 
14. Nucula corbuliformis (r). 
15. Paleeoneilo plana (r). 
16. Leptodesma lichas (a). 
17. L. potens (c). 
18. Leiopteria cf. sayi (a). 
19. Pterinopecten vertumnus (r). 
20. Goniophora chemungensis (c). 
21. Cypricardella gregaria (c). 
22. Bellerophon (Ptomatis?) rudis (c). 
23. Pleurotomaria (Clathrospira?) capil- 
laria (a). 
24. Tentaculites cf. bellulus (a). 
25. Manticoceras patersoni (r). 
The presence in this fauna of such Hamilton species as Cypricar- 
della gregaria, Nucula corbuliformis, Pterinopecten vertumnus, and 
other species having close affinities to, if not identical with, Hamilton 
species is worthy of note. The general character of the fauna, how- 
ever, indicates an horizon near the boundary between the Nunda and 
the Chemung faunas, but above the base of the Chemung formation. 
It contains six of the fifteen diagnostic Chemung species named or 
p. 57.
