FAUNULES OF THE HOLLOWING RUN SECTION. 
By E. M. Kindle. 
Zones 1-8 of Hollowing Run section {11^51^ A). — The dark shales of the 
upper five of these zones contain iSpirifer pennatus, Tropidoleptus 
carinatus, Chonetes coronatus, and other characteristic species of the 
Hamilton formation in abundance. The purpose of the present inves- 
tigation being the study of the faunas above the Hamilton, to which 
these zones belong, detailed collections were not made from them. 
Zone 9 of Hollowing Run section (1^4- A). — This zone is concealed. 
The 400 feet which White estimated it to represent probably include 
the Genesee shales and some of the Hamilton beds. 
Zone 10 of Hollowing Rim section {11^5 'J A). — The 110 feet of beds of 
this zone appear to be entirely barren. Their lithological characters, 
together with their position in the section, indicate that they belong 
to the Nunda (Portage) formation. 
Zone 11 of Hollowing Rim section (IJjBJ+A). — The 30 feet of shales 
of this zone hold the following faunule: 
Faunule of zone 11 of Hollowing Run section {1454 A). 
[a, abundant; c, common; r, rare.] 
1. Cladochonus sp. (r). 
2. Stropheodonta (Leptostrophia) inter- 
strialis (a). 
3. Buchiola speciosa (c). 
4. Palaeoneilo filosa (r). 
5. Macrodon cf. hamiltonise (r). 
This faunule, like the following, is distinctly Nunda in composition. 
Zone 12 of Hollowing Run section (14S4- A). — This zone contains the 
following faunule: 
Faunule of zone 12 of Hollowing Run section ( 1454 A ) . 
[c, common; r, rare.] 
1. Aulopora sp. (c). I 4. Coleolus acicula (r). 
2. Reticularia lsevis (r). 5. Orthoceras bebryx var. cayuga (r). 
3. Leda di versa (r). I 6. Goniatites sp. (r). 
Reticularia Isevis is represented by two well-preserved individuals. 
The beds containing this interesting species outcrop 22 paces above 
milepost 132. 
Zone IS of Hollowing Run section (11^1^ A). — The 200 feet following 
the last zone appears to be barren. 
Zone H of Hollowing Rum section (l/ff>J+ A). — This zone contains the 
following species:
