476 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Juiie 19, 



In the following list I liave recorded only such species as I col- 

 lected and have had time to examine ; and with respect to some forms 

 of TerebratulcB, I have omitted them for the present, in consequence 

 of the difficulty which their variation in form presents.
