174 The American Geologist. March, 1903. 
Litchfidd tozvnshit', Herkimer Co., N. Y. 
Onondaga. Covered slope, 15 ft. Coeymans, 80 ft. 
Manlius about no feet. 
The upper "So feet not well exposed, but parts can be seen in 
various places. 
Cobleskill member, 30 feet. 
Thin, irregular bedded gray to yellowish impure limestone 
abounding in the fossils of the Coralline limestone. Many 
of the species from this place are noted in the fauna listed 
above. 
Bertie formation. From the Cobleskill member down to the 
Enryptcrns beds the steep hillside for 60 feet does not ex- 
pose the strata. The writer is uncertain whether the strata 
of this zone should be added to the Manlius or the Bertie. 
They are probably more correctly referred to the latter. 
Waterlime, or the "drab colored layers of the Onondaga salt 
group." Near the top occur Eiirypterus rcniipes, Ptery^otus 
■macropthahnns, Dolichopteriis macrochirus, Pseudonisciis 
roosei'clti^ etc. Niagara absent. Cliriton thinning from 200 
feet in the west to 50 feet in the east. Medina absent. Oneida 
thin, resting on the Frankfort of the Champlainic. 
Vicinity of Rondoiit, Ulster County, N. Y. 
Onondaga averaging for Ulster county 60 feet. Esopus 200 to 30c 
feet. Oriskany 30 feet. Kingston and Becraft about 40 feet. New 
Scotland 60 to 70 feet. Coeymans 30 to 60 feet. 
Manlius yy feet. 
Ribbon limestone (6' to 8") at top, tlien Stromatopora lime- 
stone (8'). Tentaculitc limeston^ (14'). and the cement 
beds (40 feet). 
Cobleskill limestone 7 feet. Abounds in the corals of this form- 
ation. One mile north of East Kingston this member has 
thinned to five inches (Darton). Farther north it is unknown. 
Upturned Hudson River slates. 
Port JerviSj Nezv York. 
Beneath the llelderbergian occur the following formations : 
Manlius, 126 feet. 
Spirifer vanuxemi zone 22 feet. Waterlime abounding in Os- 
tracoda and Stromatopora, 56 feet. Coralline limestone with 
Acerz'ularia (?) incqualis, Halysites, catcniilaria var., Favo- 
sites helderbergiae var. praecedens, Diphyphyllum integumcn- 
tiwi, Stropheodonta bipartita, Orthothetes interstriatus, Rliyn- 
chonclla ( ?) lamcllata, Jl'hitfieldclla niicleolata, Calyniene earn- 
er at a, etc. 
Thin bedded limestones and shales, 42 feet. The diagnostic 
fossil of the lower half is Clwnetes jerseycnsis, otherwise the 
fauna is that of the Cobleskill member minus its corals.
