The Leda Clays of Anticosti. In their expedition to this island, referred to in the " Cana- 

 dian Naturalist," Messrs. Hyatt, Verrill, and Shaler found at the southwest point of Anti- 

 costi a deposit of blue drift clay containing Saxicava arctica. The shells occurred at ten 

 feet above high-water mark, while fragments were found fifteen feet higher. This was the 

 only fossil noticed. 



The Leda Clays of Neio Brunswick. An interesting collection of invertebrates, received 

 from Messrs. G. F. Mathew and C. F. Hartt of St. John, N. B., enables us to add to our lists 

 several new forms of very considerable importance. They mostly occurred in red clay 

 resulting from the denudation of the Devonian and Triassic deposits about the Bay of 

 Fundy.
