Station 16. Penitentiary, Albany 



At the opposite outskirts of Albany, 2 miles to the southwest 

 of the locality just mentioned, a graptolite fauna was discovered 

 by Dr Clarke near the penitentiary (station 16) in a soft, black 

 «hale of the appearance of typical Utica ehale and which also 

 •efferyefices with HOI. The fauna consists of: 



Corynoides curtus, Lapworth 



Orthograptus quadrimucronatus. Hall sp. 



Diplograptus putillus, Hall 



D. spinulosus sp. n. 



Climacograptus typicalie, Hall 



Leptobolus insignis, Hall 



Undetermined brachiopod 



The first is the most common graptolite; it entirely covers some 

 slabs. 



Station 17. Beaver park 



J. Van Deloo collected, some years ago, at the time of the 

 laying out of Beaver park, a few graptolites in a ravine in the 

 northern part of the park. These on investigation proved to be 

 Bpecimens of Diplograptus putillus. Hall, indicating 

 the Utica age of the beds of this locality, which is only a short 

 distance east of the preceding locality. 



Station 18. Normansville 



2 miles farther southwest, along the general strike of the rocks, 

 is Normansville on the Normans kill. While at Normansville 

 itself, in the sandstones and shales exposed above and below the 

 bridge, no fossils were f oiind, and the age of these rocks remains 

 in doubt, a small outcrop of shale about a mile farther up, 100 

 yards below the landing of the picnic ground on the right bank 

 of the river, furnishes graptolites (station 18). The rock is a 

 deep bluish black, thick bedded argillite with conchoidal fracture 

 and iron-stained cleavage planes. It is filled with specimeniS of 



Climacoigraptus bioornis. Hall
