36 PALJ^OKTOLOGY OF NEW YORK. 



Province of Ontario; T. Ohionisis, T. grandis and T. acuminata are known in 

 the Niagara dolomites of Ohio, and T. acmdnata from Port Byron, Illinois, but, 

 strangely enough, we have no knowledge of the occurrence of any species of the 

 "■enus in association with the great numbers of Monomerella and Dinocolus 

 in the rocks of the same age in Wisconsin ; T. acuminata has been found by 

 LiNDSTROM in association with T. Lindstmmi, on the islands of Gotland and 

 Faro ; T. Wisbi/msis, Davidson and King, is a little known species from the 

 former island. The age of the Swedish specimens is that of the Aymestry and 

 Wenlock limestone of Great Britain.
