Report of the State Geologist. 



This species is reported from Copley's quarry at Oneonta. 1 A 

 comparison of specimens from the two localities fails to prove them 

 precisely similar; but the North Norwich specimens are nearer 

 this species than any of the others figured in this work. 



14. Modiomoipliit, sp. (a broken specimen). (rr) 



15. Glossitex (lepras* /(.s, Hall. (rr) 



A single specimen that apparently belongs to this genus and 

 species. 



16. PcdcBqneilo constricta (Con.), Hall. (rr) 



17. Orthis, sp. (rr) 



18. Leptodesma cf. Pogerui, Hall. (r) 



These specimens do not have as mucronate ears as most of those 

 figured ; but some of them resemble closely the one figured on 

 plate 21, figure 9 (Palaeontology of New York, Vol. V., Part I., 

 Lamell. I.), which is stated to be from the Hamilton shales at 

 Norwich, N. Y. 



19. Orthoihetes Ohem/imgmsis (Con.), Hall. (r) 

 Actinopteria Boydi (Con.), Hall. (rr) 



21. Phacops rcma (Green), Hall. (rr)

The quarry is of course in the Ithaca formation, and some 260 feet above 

 its base. Vanuxem mentioned the quarry, referring the rocks to the Ithaca 

 group and called it the second best locality for the "Fucoides veltun, or Curtain 

 fucoid"' = Spi ropJnjton, and stated that "fossils are somewhat numerous.'" 2 



XL ( n . On top of the hill, above the Wilkes quarry to the west of 

 Cold brook, is an outcrop of sandstone in the South Plymouth road, which is, 

 perhaps, 495 feet above the North Norwich railroad' station, making its alti- 

 tude approximately 1,500 feet .V. T. The sandstone weathers to a brownish 

 color, contains large numbers of Spirifers, and is in the Ithaca formation, which 

 i/ives a thickness of 340 feet to this formation in the hill southwest of North 

 Norwich. 



Norwich. 



XXXV O 1 . South of North Norw ich is Norwich township which lias 

 been carefully described by J. M. Clarke, 8 and those interested in the geology 

 of tlif Chenango valley are referred to that report for the description of this
