EARLY DEVONIC HISTORY OF NEW YORK AND EASTERN NORTH AMERICA I I I 



Palaeoneilo sp. ? 



Plate 28, figures 15, 16 



A small highly arched and very short species with projecting umbone. 

 Locality. Presque Isle stream. 



Nuculites cf. oblongatus Conrad and ellipticus Maurer 



Plate 28. figure n 



The single observed specimen of this genus is very similar to either of 

 the cited species (which may prove to be identical), one from the Hamilton 

 fauna of New York, the other from the Coblentzian of the Rhine. 



Locality. Edmunds Hill. 



Nucula cf. krachtae A. Roemer 



Plate 28, figures 17, 18 



Nucula krachtae A. Roemer. Verstein. des Harzgebirges, 1843. p. 23, pi. 6, fig. 10 

 Nucula krachtae Heushausen. Lamell. des rhein. Devon. 1895. p. 47, pi. 4, fig. 20 

 Nucula cf. krachtae A. Roemer. Clarke. N. Y. State Mus. Bui. 107. 1907. p. 232 



I am disposed to identify with this well known Coblentzian species a 

 small trihedral Nucula of great obliquity and prominent overarching beaks. 

 Locality. Presque Isle stream. 



Palaeosolen cf. simplex Maurer 



Plate 28, figures 1-4 

 Ste p. 77 



Quite a common species is a small shell of the genus Palaeosolen 

 having narrow elongate ensiform valves clearly gaping at the anterior 

 extremity. The umbonal ridge is not sharp, but the postumbonal slope is 

 crossed by direct vertical lines which are more prominent than those on the 

 lateral slopes. Radial lines on the posterior slopes are very obscure. The 

 valves so far seen are always in conjunction. I bring this shell into com- 

 parison with Maurer's P . simplex from the lower Coblentzian, 1 although 

 it is somewhat more strongly marked posteriorly. 



Locality. Presque Isle stream. 



Cypricardella sp. 



Plate 28, figure 5 



A small tenuous shell, oblique oval in form, represents a species not 

 completely known. 



Locality. Presque Isle stream.
