REPORT OF THE STATE PALEONTOLOGIST I903 201 



tocoelia flabellites, Spirifer tribulis, Beach ia 

 suessana immatura, Tentaculites acula, Dia- 

 phorostoma desmatum, etc. and, near the top, there are 

 many specimens of Chonetes hudsonicus. 



The upper 258 feet of calcareous sandstone contain in the lowest 

 beds, Spirifer cumberlandiae, S. concinnoides, 

 etc. but fossils are rare in the lower 100 feet; the upper 158 feet 

 contain the typical Hipparionyx fauna. 



Esopus, Schoharie and Onondaga are wanting in Mar3dand and 

 farther south, the ]\Iarcellus being deposited on the eroded Oriskany. 



Conclusions 



From the above it is seen that the Manlius is faunally very similar 

 in the New York and New Jersey sections but differs in the 

 Maryland section in that the latter contains many such Coeymans 

 fossils as the bryozoan Orthopora and brachiopods closely resem- 

 bling U n c i n u 1 u s c a m p b e 1 1 a n u s (Hall) and G y p i d u 1 a 

 gal eat a (Dalman). The latter also contains such Cobleskill 

 species as Calymmene camerata Conrad. 



The Coeymans of all the sections is similar in the development of 

 chert in the middle beds. Sections i, 3 and 4 agree in having a 

 basal coral zone while 1,2, 3 and 4 agree in having the upper beds 

 shaly in character, with Gypidula galeata (Dalman) 

 abundant in the whole of the formation. In Maryland (section 5) 

 the Stromatopora horizon is at the middle of the Coeymans while 

 the typical Gypidula galeata does not occur below the 

 upper beds. 



The New Scotland of all the sections is very similar, lithically 

 and faunally. Spirifer macropleura (Conrad) is found 

 in the whole formation in all the regions with the possible exception 

 of the lower 20 feet of section 4 and the upper portion of section 2 ; 

 in the latter, Gypidula pseudogaleata (Hall) is also 

 present, thus closely resembling the Becraft. Edriocrinus 

 pocilliformis Hall occurs in the lower beds of section 5 

 while it was not found earlier than the Becraft at Trilobite moun- 

 tain.
