introductory note. 



The fossil remains herein described were collected by Messrs. 

 Hugh Fletcher and J. McDonald, in October, 1886, at the ex- 

 tremity of Cape George, Antigonish Co., Nova Scotia. In age 

 the}^ correspond most probably with those of Divisions "C " and 

 " D " of the Arisaig Section in Nova Scotia, and to the Niagara 

 and Lower Helderberg of New York State and Ontario. They 

 are therefore referable to the Silurian epoch. Some of the 

 forms examined appear to be closely related to species from 

 various localities in the State of New York, whilst others seem 

 to be more nearly related to well-known European forms of 

 Wenlock and Ludlow age. Those forms, which to us appear 

 to be distinct from both the American and European species 

 already described, are herein briefly described and their char- 

 acters pointed out 



ANNELIDA. 



\. Serpulites longissimus, Murchison. N. var. Under this 

 designation there have been placed the remains of a large anne- 

 lid which is undoubtedly very closely related to the above 

 Ludlow species of Britain. It attains a great length and measures 

 ten millimetres in breadth. The surface appears to he smooth, 

 hovvevei-, in which respects it differs somewhat from Murchison's 

 species. In breadth, the Canadian form is also perhaps less 

 broad, and on the whole may be considered a variety of the 

 European Serpulites lonylssimits.
