A third series of outcrops begins with a cliff on the north side 

 of the creek, about 115 feet above the base and reaches to 150 feet. 

 The shales of this are lithologically identical with the underlying 

 rock. These beds contain : 



Cyathodictya ? tubularis nov. (cc) 



Glossograptus quadrimucronatus mut-. cornutus Rued. (c) 



Diplograptus (Mesograptus) putillus Hall (cc) 



Lasiograptus eucharis {Hall) (r) 



Spatiopora sp. (r) 



Leptobolus insignis Hall . (c) 



Lingula curta Hall (c) 



Rafinesquina alternata (Emwow^) (r) 



Orthoceras sp. • (r) 



Ulrichia ? bi vertex Ulrich (c) 



Primitiella unicornis Ulrich (c) 



The most novel element of this association is Glosso- 

 graptus quadrimucronatus mut. cornutus. 

 This characteristic form has before been known to us only from 

 the Rural Cemetery beds near Albany which we had referred in 

 Bulletin 42 to the Utica. It is there associated with D i p 1 o g r . 

 (Mesogr.) putillus and Corynoides cali- 

 c u 1 a r i s . It is safe to infer on the strength of this form that the 

 Rural Cemetery beds and this portion of the Canajoharic beds be- 

 long to the same horizon. Some layers are profusely covered with 

 the problematicum termed here Cyathodictya? tubularis. 

 This fossil is described in the paleontologic notes at the eftd of this 

 paper. 



The fourth series of beds is exposed in a cliff reaching from 

 150 feet above the base to about 270 feet. These beds contain: 



Cyathodictya ? tubularis nov. (c) 



Corynoides calicularis Nicholson (cc) 



Glossogr. quadrimucronatus mut. cornutus Rued. (cc) 



Diplograptus (Mesogr.) putillus Hall (cc) 



Prasopora simulatrix Ulrich (c) 



Lingula curta Hall (c) 



Triarthrus becki Green (cc) 



Calymmene senaria Conrad (r) 



Ulrichia ? bivertex Ulrich (c) 



Triarthrus becki, which before had not been noticed, 

 appears in this last division about 40 feet from the base in great 

 numbers. Glossograptus quadrimucronatus 



mut. cornutus and Corynoides calicularis
