In the Fourth District, there are few fossils 
belonging to the Polyparia, but some of these 
forms are abundant. The little Millepora gra¬ 
cilis is found from one extremity of the district 
to the oilier. There is also a species of Rete- 
pora which is equally abundant; but beyond 
these two forms, the species are all limited, and 
occur but rarely. Near Bath, and at Chemung, 
there is a species of Cyathophyllum which has 
not been seen elsewhere; and in one or two 
localities, I have seen a specimen of the Tur- 
binolopsis. 
At Ithaca, Hector and Enfield in Tompkins 
county, the fossil of which the accompanying 
figure is an illustration, is found in considerable 
numbers. It occurs in single detached speci¬ 
mens, or in tufts which appear to have centered 
in a single base or root. At first view, it appears 
like a species of Filicites; but from its uniform 
size, the regular angle at which the leaves are 
given off from the stipe, and the absence of 
carbonaceous matter, it seems more like the 
tentaculated fingers of a crinoidean, or perhaps 
more analogous to the Sertularia. 
The structure is so minute, that I have thus 
far been unable to satisfy myself of its proper 
relations, and it is left for further investigation. 
The specimen figured presents parts of several 
stipes, all apparently centering at one point at 
the base, and slightly diverging above.
