ANAEYTICAE DISCUSSION OE THE HORNERSTOWN EAUNA. 



The total fauna of the Hornerstown marl is small and the 

 fossils from that portion of the formation beneath the shell bed 

 have been rarely met with. Whitfield has described two species- 

 of Cucullaea from the marl pits of J. S. Cook, near Tinton Falls, 

 but no collections were secured by the writer from this locality. 

 The same species, however, were found near Hornerstown
