formation would be represented in this section, has not been 

 determined. It seems probable that since the period was one of 

 submergence, the latter view is more nearly correct, though in 

 this section Chonetes jersey en sis, which is the char- 

 acteristic fossil of the lower Decker Ferry formation in the 

 Nearpass section, is here equally as abundant and in size averages 

 larger. This fossil, in the cut at Accord, is sometimes so plen- 

 tiful as to make a band a fraction of an inch in thickness. From 

 the railroad cut the following species were obtained. 



1 Favosites sp. 



2 Monotrypa corrugata Weller 



3 Rhynchonella ? lamellata Hall 



4 A. reticularis Linne 



5 Chonetes jerseyensis Weller 



6 Rhipidomella cf. preoblata Weller 



7 RlwnGhonella deckerensis Weller 



8 R. litchfieldensis Schuchert 



9 Spirifer cf. corallinensis Grahati 



10 Spirifer sp. iindet. 



11 Stropheodonta bipartita Hall 



12 Pterinea emacerata Hall 



A favorable place for the collection of fossils from the basal' 

 arenaceous layer is at Fiddlers Elbow on the Delaware and Hud- 

 son canal a short distance from the railroad cut. At this place 

 the canal is partly excavated in the shales and the limestone is 

 found a little higher up by the canal bank. At some points the 

 underlying shales have weathered aw^ay leaving the limestone 

 above as a slightly projecting ledge. From the basal arenaceous- 

 layer the following species were obtained. 



1 Favosites sp. 



2 Monotrypa corrugata Weller 



3 Atrypa reticularis Linne 



4 Gypidula cf. galeata Dalman 



5 Stropheodonta bipartita Hall 



6 Spirifer sp. 



At this place a number ' of rather poorly preserved specimens 

 of a pentameroid were found. They approach closely Gypid- 

 ula galeata of the Coeymans limestone and may prove to 

 be identical with it. 



The Cobleskill limestone is exposed a little higher near an old 

 limekiln. The rock is here much weathered and fossils are 

 readily obtained though not in a well preserved state. A feature 

 of the collection from the Cobleskill obtained at this point is 

 the large number of gastropods and cephalopods found, and the 

 fauna is more nearly like the normal fauna of the Cobleskill of 

 Schoharie county than at any other section that has been studied
