Gap (T.V.A. 171-SE) Quadrangle. 
Edinburg formation (Liberty Hall facies) in Virginia: 1 mile northwest of 
Lexington, Lexington (15’) Quadrangle. 
Effna formation in Virginia: McNutt Quarry, 12 miles southwest of Bland,

Discussion—This species is characterized by its moderate size, elongate-oval 
outline, subparallel sides, and acutely angular beak. It is larger than L. decorti- 
cata, new species, and with more parallel sides. Its elongate form distinguishes it 
from L. galba, new species.
