At this locality specimens of Leptaena rhomboi- 

 dalis are plentiful and unusually well preserved. At the top 

 of the Cobleskill in the portion that is transitional into the Ron- 

 dout there are found thin bands of limestones separated by shaly 

 partings. The shaly layers weather to a drab color and are 

 easily removed from the face of the quarry. These thin layers 

 contain quite abundantly Orthothetes interstriatus 

 Hall and Leperditia scalaris Jones. The limestone 

 bands are crowded with Whitfield e 11a sulcata Van. 

 and Spirifer vanuxemi Hall. Orthothetes in- 

 terstriatus Hall and Leperditia scalaris Jones 

 are also found in the limestone bands. In the Nearpass section 

 south of Port Jervis at the top of the Cobleskill there are found 

 similar limestone bands characterized by many Beyrichias of 

 which there are several species. In the latter section in these 

 limestone bands brachiopods are also found, but Leperditia has 

 as yet not been observed. 



Northeast from this outcrop the Cobleskill and Decker Ferry 

 formations are obscured for about a mile, but the Decker Ferry 

 formation is again seen on the farm of Mr Cuddeback just in 

 rear of the house. The Rondout is shown a little higher up on 

 the ledge and the Manlius and Coeymans limestones a short dis- 

 tance farther to the west. A short distance to the west of the 

 house of Mr Case and north of the outcrop back of Mr Cudde-
