bridge, and the sandstone is probably in Prof. White's Chemung, while 
the -shales are from the top of his Genesee. The sandstone is similar 
to the blue flags of the Hudson River region above Kingston, though 
not so well developed. 
Fauna of No. 1476 F2. 
Tellinopsis subemarginata (Con. ) Hall (a) 
Very good and characteristic specimens of this species. 
Nuculite's oblongatns (Con.) (r) 
Paheoneiloconstricta (Con.) Hall (c) 
Some of the specimens have identically the same form as those from the 
Cayuga Lake region of New York, so there is not the least doubt in ref- 
erence to the specific identification. 
Palseoneilo muta Hall (rr) 
Nuculites triqueter Con (c) 
Leda diversa Hall (rr) 
Leda rostellata (Con. ) Hall (rr) 
Orthonota carinata Con (rr) 
Prothyris lanceolata Hall (rr ) 
Prothyris planulata Hall (?) (rr) 
Pholadella radiata (Con.) Hall (rr) 
Nucula corbuliformis Hall (a) 
Probably the most abundant species of this fauna, and good typical 
specimens of the species. 
Goniophora carinata (Con.) Hall (?) (rr) 
Modiella pygrmea (Con.) Hall (rr) 
Modiomorpha mytiloides (Con.) Hall (c) 
Grammysia lirata Hall ( ?), (r) 
Orthonota ( ?) parvula Hall (rr) 
Phacops rana (Green) Hall (c) 
Spirifera frmbriata (Con.) Bill (r)

Hyolithcs aclisHall (c) 
Coleolus tenuicinctum Hall (rr) 
Loxonema delphicola Hall ( ?) (rr) 
Pleurotomaria itys Hall (?) (c) 
In the imperfect condition of these specimens it is difficult to distinguish 
between the above species and P. capillaria Con., but the number and 
character of the revolving stria? agree more nearly with P. itys Hall. 
Bellerophon leda Hall (rr) 
Dalmanites (Cryphaeus) booth! (Green) Hall, possibly the variety calliteles 
Green '. (rr) 
Cyclonema hamiltoniaB Hall (?) (rr) 
Bellerophon brevilineatus Con. (?) (rr) 
( ?) Sphenotus cf. cuneatus (Con.) Hall (rr) 
(?) Leiopteria or Leptodesma, not well enough preserved in order to decide 
which genus.
