DESCRIPTION OF FOSSII.S* 



LINGULA Bruguiere 



Lingula brainerdi sp. nov., PI. 18, figs. 2, 3 



Shell subredtaugular, expanding only slightly toward the 

 front; beak small; apical angle very obtuse; posterior regularly 

 rounded; front nearly straight, with gently curved angles. Great- 

 est convexity about middle of valves; the anterior slope flattened. 

 Surface marked by closely arranged fine lamellose lines of growth 

 and partially exfoliated specimens show numerous fine radiating 

 lines which are more common and strong near the middle of the 

 valves. 



The figures do not show the charadlers well owing to the 

 poor specimens from which they were drawn. Better material 

 has been obtained since from Valcour Island and will be figured 

 at a later date. 



Locality. — A 2. Crown Point, N. Y. Base of the Chazy, 

 Valcour Island and Isle lyaMotte. 



*A11 the fossils here described and figured are in the Museum of Pal- 

 eontology of Cornell University.
