Point. One hundred five species are identified from the collection made 

 from this formation of which the following appear in the Lenoir limestone 

 of eastern Tennessee : 



Camarella varians Billings. 



DinortMs platys Raymond. 



Dinorthis sfrophoinciioidvs (Raymond). 



EurychUm a hiti iii arti in a fa ( Ra y mond ) . 



Hebertclla nihjaris liaymond. 



Holopea scrutator Raymond. 



Leperditia Umatnla Raymond. 



Maclurites magnus Lesueur. 



Rafincsquma incrassata (Hall). 



RapMstoma stamineum (Hall). 



Scenella rohusta Raymond. 



Stylaria parva (Billings). 



The comparison leads to the conclusion that the Chazy basin of New York 

 and of eastern Tennessee were directly connected and inter-migration took 

 place freely. Only three of the above species occur in central Tennessee, 

 these being the only representatives of the migrants from the Atlantic 

 coastal area that reached the Gulf of Mexico Embayment and the basins of 

 the eastern Chazyan seas. 



Kentucky, Central Netv York a/nd Canada. The beds deposited during the 

 Stones River time in the state of Kentucky are exposed at the base of the 

 falls at Highbridge. The following species collected from that locality are 

 characteristic of the Lebanon : 



Drepanella ampla Ulrich. 



Drepanella elongata Ulrich. 



Eurychilina aequalis Ulrich. 



Eurychilina granosa Ulrich. 



Liospira progne (Billings). 



There is no known deposit of Stones River age outcropping in the state 

 of Ohio, but the distinctly Stones River fauna occurring in the Pamelia lime- 

 stone of central New York indicates that a passageway existed which con- 

 nected the latter area with Kentucky and Tennessee. 



The following is a list of fossils occui ring in the Pamelia limestone as 

 recorded in Bulletin 92, United Stati-s National Museum: 



Bathyurus acutns Raymond. 



Cyrtodonta hrevinscula Billings. 



Ifclicotoma whiteavesiana Raymond. 



Isocliilina ? clavigera (Jones). 



Tsochilina clavigera clarAfracta (Jones). 



Leperditella ? lahellosa Jones. 



Leperditia amygdalina Jones. 



Leperditia dalthica primaeva Jones. 



Leperditia falulites (Conrad).
