4. Spirifer mesacostalis, Hall (?). (it) 



5. IAorhyThckus globuUforrms (Van.), Hall. (c) 



6. Atrypa reticularis (Lin.), Dal. (r) 



7. Rhynchonella (Pugnax) pugrms (Martin), Dav. (r) 



Specimens rather small and poorly preserved, but pretty clearly 

 of this species. 



8. Cyrtina JIa/niltonensis, Hall. (rr) 



9. Sftropheodonta demissa (Con.), Hall. (rr) 



10. PalcBoneilo filosa (Con.), Hall. (c) 



11. Pcdceoneilo cf. const ricta (Con.), Hall. (rr) 



One specimen better preserved approaches this species in mark- 

 ings and form. 



12. Mytilarca carinata, Hall (?). (rr) 



13. Schizodus cf. appressus (Con.), Hall. (r) 



The specimens are nearer to figure 8, plate 75 (Palaeontology of 

 New York, Vol. V., Part I.), of the above species than to any other 

 form. 



14. Lyriopecten cf. tricostaPus (Van.), Hall. (rr) 



A left valve that agrees quite well in its plications with 

 L. macrodontus H. of the Hamilton. 



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



Crushed, but much like this species. 



16. Crinoid segments. (a) 

 The Chenango Forks railroad station is at 901 feet, which makes the altitude 



of the quarry approximately 964 feet A. T. 



XXXVI A 2 . Near the top of the hill above A 1 are loose, blocks of stone 

 containing plenty of specimens of Liorhynch iis globuUformis (Van.), Hall, and 

 Rhynchonella (CamarotwcJ/ia) titevensi, Hall, which are probably from the 

 next fauna above that of the lower exposures at Chenango Forks. The 

 following species were noted in these loose blocks : 



1. Liorh/yTwhus globuUformis (V an.), Hall. (c) 



2. lihynchonella (JJamarotoechia) Stevens/ (Hall), Hall and Clarke. (c) 



3. Rhyiwhonella {Camarotwhia) eximia (Hall), Hall and Clarke. (c) 



It is probable that these specimens should be carefully com- 

 pared with Ji. congregata (Con.), Hall, of the Hamilton, which 

 seems to be a closely allied species.
