266 Forty-sixth Report on the State Museum. 



Tropidoleptus carinatus^ Conrad. 



Orthoceras crotalmn^ Hall (?). 



Grammysia. 



Pholadella radiata, Conrad. 



Chofietes (?) rmicronata, Hall. Possibly Tropidoleptus carinatus^ 

 Conrad, but I am quite sure that on one side are the proximal ends of 

 two spines. 



Chonetes dejlecta, Hall (?). This specimen may be C. 'inucronata, 

 Hall, but it is considerably larger than the figured specimens of that 

 species, and apparently agrees well with the figures of C. deflecta, Hall. 

 However, Prof. Hall writes that C. dejlecta, Hall, may be, perhaps, 

 only another phase of C. mucronata, Hall.* 



Gcmiatites . Simply a fragment. 



JPtilodictya {Stictopora). sp. Fragment. 



Chonetes. Apparently young of C. coronata, Conrad. (See Pal. 

 N. Y., vol. iv, pi. 21, Fig. 10 a, b.) 



Two -\- miles down the river from 498 I, and three-fourths of a mile 

 from West Edmeston is an exposure of shales in Ordway creek, which 

 has been numbered 498 K. The most abundant fossil is Nyassa arguta, 

 Hall. The fauna in full is given below: 



Nyassa arguta, Hall. 



Orthis. Specimens very imperfectly preserved in a thin sandstone 

 stratum. 



Nuculites triqueter, Conrad. 



Modiella pygniaea, Conrad. 



Palmoneilo constricta^ Conrad. 



JRhynehonella. Small specimens and specific characters not well 

 defined. 



Chonetes . 



Athyris spiriferoides, Eaton. 



Spirifer . 



Pterinea flahella, Conrad . 



Liopteria DeKayi, Hall (?). 



Honialonotus DeKayi, Green. 



In the thin sandstone, as is also 



Spirophyton velum, Vanuxem. 



Quite extensive collection of fossils was madej at different places in 

 Brookfield, Madison county, and the following lists will give'a good 

 idea of the middle Hamilton fauna of Central !New York. 499 A, on 

 the summit of Beaver hill, one and one-half miles east of Brookfield,
