 miles northeast of Woodstown, and the same distance southwest 

 of Harrisonville, the upper shell bed of the Hornerstown marl 

 is exposed west of the road, all the contained fossils being stained 

 a deep chocolate-brown color. The following species have been 

 recognized : 



BRACHIOPODA.

ANALYTICAL, DISCUSSION OP THE HORNERSTOWN FAUNA. 



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
