" This is (as far as is known to the describers) not only the 

 first instance of finding scutcheoned fishes in this country, 

 but also the lowest position in which remains of vertebratae 

 have been found, if we except defensive fin bones, which 

 occur in New York, nearly in the same geological position, 

 viz : in the corniferous group and the scales of fishes, 

 which the Professors Rogers traced throughout the Clinton 

 group of Pennsylvania and Virginia."
