184 CATALOG OF FOSSIL FISHES IN THE MUSEUM 



It thus seems to us that the forms described by Clarke and by 

 Williams from isolated scales and plates, represent a single species; 

 and for this Clarke's specific name, devonicus, has priority. 



This species is represented in the Buffalo museum by a considerable 

 series of scales, cranial plates, fulcra, etc., preserved singly or in 

 groups, on small pieces of shale. All are from the Rhinestreet shale 

 (Portage), on the shore of Lake Erie, near Sturgeon Point, N. Y.
