horizon here is evidently above the Ithaca shale. Only a few 

 fossils were obtained. Palceorieilo constri^a, Chonetes scitula and 

 Nucula diffidens being the most abundant. 



Station 2. — Above the cascade, 60 feet higher than Station /, 

 the more common species are Leiorhynchus mesacostalis, Modio- 

 morpha subalata var. chemungensis, Aniboccelia iimbonata, and 

 Niicula diffidens. 



Station j. — At this station, 15 feet above the last, the pre- 

 dominant fossils are Modioniorpha svbalata var. chcmungensis, 

 Chonetes setigera and C. scitula. 



Station 4.. — The predominant fossils at this point which is 160 

 feet above Station i, are Spirifer inesacostalis and ^. mesastrialis. 

 Some of the associated fossils are Cyrtina hamiltonensis , Rhyncho- 

 nella exiniia, PalcEoneilo constricta^ and AHinopteria perstrialis. 



Station 5. — ^180 feet above Station i. 



A calcareous layer about 18 inches thick occurs here contain- 

 ing an abundance of crinoid stems and Monticuliporoid corals. 



The following species were obtained here: Schizodiis cheniung- 

 ensis, Glossites depressus, StiHopora ineeki, Microdon gregarius, 

 ABinopteria boydi, Callopora sp. 



• Station 6. — 195 feet above Station i. 



The abundant and chara(5teristic fossils at this horizon are 

 Atrypa reticularis, Prodiinella speciosa, and Spirifer mesacostalis. 



Station 7. — 350 feet above Station i. 



This station is about ^ mile below the village of Newfield 

 at the first rock exposure below the flour mill. A remarkable 

 recurrent Portage fauna occurs at this locality entirely above the 

 Ithaca group fauna. The following species were obtained : Glyp- 

 tocardia speciosa, Lunulicardiuvi fragile, PalcB07ieilo coyistrifla, Co- 

 leolus sp. 



Prof. Williams has found, from about the same horizon, the 

 following additional Portage species: Ling^da coviplanata, Bcl- 

 lerophon mcera, Strophodo?ita mucronata. 



Above this station for a distance of more than 300 feet, the 

 rocks consist of shales and thin bedded sandstones, and appear 

 to be barren of fossils.
