PALEONTOLOGTCAL BULLETIN, No. 25. 



Verbal communication on a New Locality of the b'refin River Shales con- 

 taining Fishes, Insects and Plants in a good stats of preservation. 



By E. P. Cope. 



Owing to the rather softer character of the matrix the characters of the 

 fishes could be worked out with much nicety. A collection which he had 

 recently received includes sixteen species, all new. Their names are as 

 follows: 

 ? Chromididse. 



Priscacara serrata Cope. 

 " cypha Cope. 



" Hops Cope. 



Percidse. 



Mioplosus abbreviates Cope. 

 " labracoides Cope 



" longus Cope. 



" beanii Cope. 



Asineopidse. 



Asineops pauciradiatus Cope. 

 1 Aphredodiridae. 



Erismatopterus endlichii Cope. 

 Amphiplaga brachyptera Cope. 

 Clupeidse. 



Biplomystus dentatus Cope. 

 " analis Cope. 



" pectorosus Cope. 



" humilis Leidy. 



" alius Leidy. 



Osteoglossidse. 



Dapedoglossus testis Cope. 



" ? encaustus Cope. 



Of the above genera all but two are new to science, and all of the species 

 but three are likewise new. From the present collection something like 

 a general view of the ichthyological fauna could be obtained, since the 

 predominant types were probably represented in it. Priscacara is a 

 Pharyngognath allied to the Chromididce and Pomacentrida, most nearly 

 to the former ; and Dapedoglossus is not far removed from Arapcema and 

 Osteoglossum. The facies of the fauna is of a mixed character, both fresh 

 water and marine types being present. The largest species is the Osteo- 

 glossum encaustum ; the second in size the Diplomystus dentatus, which 

 exceeds the moss bunker (Brevurtia menhaden). 



The descriptions of the species and genera are in process of publication 

 in the Bulletin of the U. S. Geol. Survey Terrs.
