Chonetcs coronatus (Conrad), Productella cf. spinuKcosta Hall, Rhipi- 

 domella vanuxemi Hall, Camarotoecliia sp., Tropidoleptus carinatus 

 (Conrad), Spirifer mucronatus (Conrad), Spirifer audaculus (Conrad), 

 Ambocoelia umbonata (Conrad), Nucula bellistriata (Conrad), Nuculites 

 ohlongatus Conrad, Palaeoneilo constricta (Conrad), Palaeoneilo fecunda 

 Hall, Palaeoneilo emarginata (Conrad), Liopteria cf. conradi Hall, Mo- 

 diella pygmaea (Conrad), Aviculopecten princeps (Conrad), Cypricar- 

 dclla bellistriata (Conrad), Palacosolen minutus Prosser, Pleurotomaria 

 itys Hall ( ?), Bellerophon sp., Homalonotus dehayi (Green). 



About three-fourths of a mile east of the Queen City hotel the following 

 species were collected: Stroplieodonta (Leptostrophia) perplana (Con- 

 rad), Rhipidomella vanuxemi Hall, Rhipidomella leucosia Hall, Tropido- 

 leptus carinatus (Conrad), Sprifer mucronatus (Conrad), Palaeoneilo 

 emarginata (Conrad), Cypricardella tenuistriata (Hall), Crinoid seg- 

 ments. 



Farther up the road are exposures of the Genesee and Woodmont shales 

 of the Jennings formation. The stratigraphic order of this section is 

 complicated by faulting and folding as determined by Dr. E. B. Eowe. 



A layer of slightly arenaceous shale on the National Eoad half way 

 up the hill northeast of Cumberland furnished the following species: 

 Chonetes mucronatus (Conrad), Chonetes sdtulus Hall, CJionetes setiger 

 (Hall), Camarotoecliia prolifica Hall, Spirifer mucronatus (Conrad), 

 Vitulina pustulosa Hall, Nuculites oblongatus Conrad, Palaeoneilo con- 

 stricta (Conrad), Pleurotomaria itys (?) Hall (broken specimens). 



Eather heavy arenaceous shales on the National Eoad near the top of 

 the hill and opposite Cemetery northeast of Cumberland gave the follow- 

 ing list: Scliuchertella sp., Chonetes sdtulus Hall, Chonetes setiger 

 (Hall), Chonetes lepidus Hall, Atrypa reticularis (Linne), Cyrtina ham- 

 iltonensis Hall, Spirifer granulosus (Conrad), Grammysia bisulcata 

 (Conrad), Pterinea flabellum (Conrad), Modiomorpha concentrica 

 (Conrad). 



The shales and sandstones on the 01dto\vn Eoad, east of Maryland 

 Avenue, Cumberland, have furnished the following list: Lingula nuda 

 Hall ( ?), Schnchertella sp., Clioncies mucronatus Hall, Chonetes scitulus
