size. It bears two strong concentric ridges on the upper surface of the whorl, 

 and four or five such ridges on the lower surface. Concentric lines fine and 

 closely crowded. Abundant in a single thin layer. 



Pleurotomaria Itys, (rare). 

 Nucula corbuliformis. 

 Spirifer mucroiiatus var. posterus. 

 Liorlujnch i/.s mesacostalis. 



On the hill next eastward of this quarry and at an elevation of 100 feet 

 above it, fossiliferous beds appear sparingly to the top. The rocks carry 

 Atrypa reticularis abundantly, one loose block from the vicinity containing 

 Leptaen a rhombo idalis. 



Station II. On the road from Burdick settlement t<> South Otselic, 

 Chenango count), one-half mile south-east of the former village, is a long 

 exposure along the highway and in the banks of a creek which the road 

 follows. 



The lowest outcrop is of Portage (Sherburne) fucoidal slabs with inter- 

 vening shale beds, often two or three feet in thickness, but without fossils. 



At 207 feet above the creek at DeRuyter, the following fossils were 

 found : 



Spirifer mucronctt/us, var. posterus (c). 

 Idorhyiicluits inesttcoxtalis (c). 

 Chonetes sciPida (c). 

 Tentaculites cf. spicukis, 

 Palceoneilo constricta. 

 Paracyclas Urata. 

 Liopteria Icevis. 

 Leptodesm < < Roge / 's i. 

 .\ ucula Gorbuliformis. 



Station III. South Otselic, Chenango county. A road entering the 

 village from the east runs for a mile or more through a deep gorge which 

 affords a tine natural exposure, supplemented by several quarries. The 

 elevation of the South Otselic hotel is eighty-eight feet below the creek at 

 DeRuyter, and the village is eight miles due south of the latitude of that 

 place. 



At the opening of the gorge on the west, the elevation is forty-five feet 

 above the hotel. Here the Portage fucoidal layers and sandy slabs (Sher- 

 bnrne sandstone) are absent. The first twenty feet are of sandy compact 

 shales, from which the following fossils were taken :
