 ous sandrock at St. Timothy on the St. Lawrence above Beauhar-

ECCULIOMPHALUS CANADENSIS, N. sp. 



Fig. 4. 

 Fig. 4. — Ecculiomphalus Canadensis. 



Description. — This species consists of a simple curved tube 

 usually about three inches in length. The larger extremity for 

 about two inches is nearly straight, and the cross section nearly 

 circular. The remainder, to the point, curved so as to make half 

 a whorl of an inch across, or a little less. In this part the tube 

 is not cylindrical but flattened laterally. In most of the speci- 

 mens the sides are more sharply rounded than the dorsal or ven- 

 tral aspects. In none that I have seen is the shell preserved, so 

 that the surface characters remain unknown. Some of the frasr- 

 ments shew that the shell near the smaller end is greatly thick- 

 ened. 



Length from two to three inches \ diameter at the aperture 

 from six to nine lines. 



Locality and formation. — Ormstown, in the Seigniory of Beau- 

 harnois, and Phillipsburgh in the Calciferous sandrock. Also in 

 the limestones of the Quebec group at Point Levi.

 half in diameter. At the aperture the cross section of the tube 

 is nearly circular, and five lines in diameter in a specimen which
