The remains of fishes, particularly their teeth, are not 

 unfrequently found in both the Devonian and Carbonifer- 

 ous strata. No classification of them has been attempted, 

 but they are readily separable into three groups, the first 

 belonging to the Devonian beds, the second to the lower 

 bed of Burlington limestone, and the third to the upper 

 bed. 



Of Crustaceans, none but those belonging to the genus 

 Phillipsia have been discovered. Three species of this 

 genus have been recognized, two in the lower, and one in 

 the middle portion of No. 7, and also in No. 8. 



The Cephalopoda, so far as observed, are confined to 

 the lower beds, and comprise but three or four genera. 



The Gasteropoda are quite numerous, both in genera 

 and species, but are most abundant in the lower beds. 



The Brachiopoda are the prevailing forms in the lower 

 beds, and are numerous in genera, species, and individ- 

 uals.
