Report of the State Geologisi, 279 



This specimen referred to is probably a variety of this species; the 

 lamellose concentric striae are coarser and the posterior extremity 

 narrower than in the specimens figured. 



Pleurotomaria capillaria, Conrad. 



Coleolus tenuicinctus, Hall. 



The higher exposures were called 502 D^, and the following species 

 were obtained : 



Spirifer graiiuUfer^ Hall. 



Tropidoleptus carinatiis, Conrad. 



JRhynchonella. 



Small form of H. congregata, Conrad, or M. pyroUfjca, Hall. 



Spirifer riiedialis, Hall (?). Imperfect specimens. 



Homalonotits DeKayi, Green. Segments only. 



Pleurotomaria capjillaria, Conrad. 



Parts of Crinoid stems. 



Liopteria DeKayi^ Hall (?). 



Modlornorpha concentrica, Conrad (?). Only a fragment. 



The above fauna shows that 502 D^ is a continuation of 502 C; 

 Spirifer granidifer, Hall, and Tropidoleptus carbiatus^ Conrad, being 

 very abundant in both stations. 



Three miles south of station 502 D a series of cliffs were examined 

 on the eastern bank of the Unadilla river. This station 503 A is in 

 the northwestern corner of Pittsfield township opposite the upper 

 river bridge and one mile northeast of New Berlin village, Chenango 

 county. 



Below the highway just at the river's edge is a bluish-gray sandstone 

 30" in thickness, with coarse arenaceous shales above. The only fossil 

 found here, 503 A^, was a single large perfect specimen of Chonetes 

 coronata, Conrad. 



Just above the highway are moderately thin arenaceous shales 

 cleaving ^dth some regularity, containing very few fossils. Those 

 found in these shales 503 A^ are so fragmentary that a specific identi- 

 fication is difficult. The most common forms are Gi-amniysia, and 

 several fragmentary specimens agree quite closely with G. bisulcata, 

 Conrad. Also several imperfect specimens of Chonetes were found. 



Then comes a 10 ' bluish-gray sandstone, 503 A^, mthout any fossils 

 so far as noticed, and above the sandstone rather thin arenaceous 

 shales, 503 A*, in which fossils are common. The fauna of 503 A* is 

 given below: 



Chonetes scitula, Hall. 



This species is very abundant in tbese shales.
