Here also is an outcrop of the fish-bearing, pyritiferous beds, 
though at present covered by a slide of earth, so that only loose slabs can 
be obtained. Fish remains are not so abundant here as at Moscow, but 
the bed is crowded with minute Brachiopoda and Gasteropoda, with some

Both above and below this, along the creek, fossils are very abundant an 
in fine preservation. Among them are Alrypa reticularis, A, rugosa, 
A. zigzag, Phacops bufo, Homalonotus DeKayi, Nucleocrinus lucina, 
and a Crinoid much resembling a Comatula. By following up, for a short 
distance, another branch of this stream, from a point one-eighth of a 
mile northwest of the village, the characteristic fossils of the Moscow 
ale may be obtained abundantly. 
Interealated between the beds of the Moscow shale, at this place, are 
lenticular masses of iron pyrites, from five to thirty feet in diameter, and 
from one to six inches in thickness. They contain fishbones and teeth in 
abundance, as well as numerous Brachiopoda, Gasteropoda and Cephalo- 
poda, and occasionally Crinoidea. 
Going north from Moscow about three miles, the road crosses Paterson’s 
Creek. A few rods above this point the ravine begins, and along the 
bottom of this for some distance is a rich spot for the fossil seeker. The 
Phacops bufo and Cacabocrinus glyptus are among the choice things that 
I have found here. 
species 0 opora, and quite a number of Bryozoa. On one small bit 
of coral I have counted five parasitic species. The corals are quite plen- 
tiful here, especially Heliophylli and Favosites. 
The Marcellus shale outcrops near Avon and LeRoy. At Littleville, 4 
mile south of Avon, both the limestone and shale of this group are 
A little farther north, along what is called the Little Coneseus, and 3 
few rods above the Erie railroad, is another outcrop.
