ly united perhaps with the drab limestone above," which he 
thinks is the Onondaga-salt group, but in reahty it is the Ron- 
dout division of the ManHus. 
Recently Dr. Clarke* has proposed the term Cohleskill 
formation to supplant the meaningless term Coralline lime- 
stone. 
THE FAUNA OF THE CORALLINE LIMESTONE. 
In looking over a t^'pical collection of Coralline or Cobles- 
skill limestone fossils, such as that of the American ]Mviseum 
of Natural History or of the Brooklyn Institute, one is im- 
pressed by the preponderance of the corals which make up the 
bulk of the fauna. While the species are few, yet the speci- 
mens of Favosites and Stromatopora are very common. The 
fauna discussed below is that of the original locality, Schoharie 
county, New York. Additional species from other places, of 
which many are at hand, will not be considered here.

Two specimens of this western New York coral are in the 
U. S. National Museum from Howe's cave near Schoharie 
(No. 10533). Upon them are growing Favosites hclder- 
bergiac var. pracccdcns, n. var. 
Diphyphyllum coralliferum (Hall).

This species has not been seen in Herkimer count)-. An- 
other closely related species is D. integumentnm Barret from 
the Cobleskill of New Jersey. 
Acervularia (?) inequalis (Hall).

1889, p. 459 and text figures. 
This characteristic fossil of the Cobleskill limestone has 
not been recorded west of Schoharie county, but it has also 
been found near Rondout, and in New Jersey, Pennsylvania, 
and Maryland. Specimens of this species never appear to be 
abundant.
