bluish, mostly arenaceous, but some are argillaceous in composition. 

 Fossils are common, tbe fauna being as follows: 



Hhynchonella congregata, Conrad. 



Part of the specimens are clearly of this species, while others have 

 the more angular plications of JR. Sappho, Hall ; but Prof. Hall says: 

 " The surface plications appear to be more angular in specimens from 

 the arenaceous beds; and the casts of the interior of some specimens 

 which I have referred to this species present distinctly angular 

 plications." * 



All of the above specimens with angular plications are from aren- 

 aceous shale. 



Spirifer 'tnucronatus, Conrad. 



Chonetes. 



Small forms which have about the same number of striae as C. lepida, 

 Hall, while in general proportions they are closely allied to C. setigera, 

 Hall. 



Chonetes scitula, Hall. 



Liorhynchus multicosta, Hall. 



Actinopteria JBoydi, Conrad (?). 



The specimens are hardly as wide in proportion to their height as 

 most of the figured forms of the above species. 



Spirifer sp. Large form with sinus and fold striated by fine 

 plications. 



Leptodesma. 



Paracydas lirata, Conrad. 



One mile from 503 D, on the eastern slope of the hill, and lower is 

 another little cliff by the roadside, 503 E. In a coarse arenaceous blue 

 shale were found: 



Spirifer mucronatus, Conrad. 



Chonetes lepida. Hall (?). 



Liorhynchus midticosta, Hall. 



Rhychonella congregata, Conrad. 



Productella. 



In the above shale the fossils are common. A few feet lower is a 

 blue thin-bedded, fine-grained sandstone quite similar to the quarry 

 stone of 503 C. 



Two and one-fourth miles from 503 E, just across the town- 

 ship line in the northern part of Morris county and one 

 and one-half miles north-east of Morris village is an outcrop
