The Ottawa Naturalist. 



[June- July 



Valley. Triplecia extans and Recept acuities occidentalis are listed by 

 Raymond as characteristic of the Rockland formation which underlies 

 the Hull near Ottawa. Both are present in the Wolfe Island Trenton 

 but are represented in the collections at hand by only two and one 

 specimens respectively. 



The collections and studies upon which this paper is based were 

 made in part during the preparation of a report* on the geology of the 

 Kingston district. After that report had gone to press, additional 

 collections were made from the old as well as from new localities. The 

 complete faunal list follows.
