No. 9.] FOSSILS FROM P. E. ISLAND — F. BAIN. 463 



Note. — (Feb. 21, 1881.) — Since the above paper was written, Prof* 

 Whitfield of New York has announced * the discovery of another 

 species of land snail in the coal formation of Ohio. It is a small 

 species, three and one-third millimeters in length, of that type of 

 pupidae having the aperture nearly vertical and armed with several 

 projecting teeth. It has besides the peculiar feature of a small nearly 

 circular notch near the upper end of the lower lip. On account of 

 this peculiarity it is placed in a new genus Anthracopupa, and the 

 species is named A. ohioensis. 



Prof. "Whitfield also mentions that he has examined the aperture of 

 Dawsonella Meeki, and finds reason to believe, from the form of the 

 callus in the aperture, and the peculiar thickening of the outer lip, 

 that it may have been an operculated shell, though he admits that no 

 trace of the operculum has yet been found. 



Note on Fossils from the Red Sandstone System of 

 Prince Edward Island. By Mr. F. Bain. 



(Read at the Meeting of the Natural History Society, January 31, 1881.) 



In the course of some short geological excursions during the 

 past summer, I obtained from the system of strata classified as 

 Triassic in Dr. J. W. Dawson's Report on the Geology of Prince 

 Edward Island, the following fossil plants : 



Walchia gracilis, Dawson. 

 Calamites gigcis, BroDgt. 

 Calamites Suckovii, Brons^t. 

 Pecopteris rigida, Dawson. 

 Pecopteris arlorescens (?), Schlotheim. 



These were taken from various localities on the north side of 

 the Hillsborough Bay and the south side of Lot 65, and occur 

 through a depth of strata amounting to more than one thousand 

 feet. 



On the Island, two distinct systems of rocks are recoo-nized : 

 the Permo-carboniferous and the Triassic. In the first of these 

 are a number of beds rich in remains of plants. But the 

 Triassic is characterised by an exceeding barrenness of well- 

 preserved organic remains.
