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. 
Dinorthis platys Raymond. 
Dinorthis strophomenoides (Raymond). 
Eurychilina latimarginata (Raymond). 
Hebertella vulgaris Raymond. 
Holopea scrutator Raymond. 
Leperditia limatula Raymond. 
Maclurites magnus Lesueur. 
Rafinesquina incrassata (Hall). 
Raphistoma stamineum (Hall). 
Scenella robusta 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 New York and 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 iocality are 
characteristic of the Lebanon: 
Drepanella ampla Ulrich. 
Drepanella elongata Ulrich. 
Burychilina aequalis Ulrich. 
Burychilina 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 occurring in the Pamelia limestone as 
recorded in Bulletin 92, United States National Museum: 
Bathyurus acutus Raymond. 
Cyrtodonta brevinscula Billings. 
Helicotoma whiteavesiana Raymond. 
Tsochilina ? clavigera (Jones). 
Tsochilina clavigera clavifracta (Jones). 
Leperditella ? labellosa Jones. 
Leperditia amygdalina Jones. 
Leperditia balthica primaeva Jones. 
Leperditia fabulites (Conrad).
