An upper tooth, or rather the tritoral area of an upper tooth, which 

 has been identified with this species by Mr. A. Smith Woodward, was 

 collected at Thedford by the Rev. J. B. Goodwillie, in 1882, and presented 

 by him to the Museum of the Survey. Its maximum length is about 

 thirty-four millimetres. A much smaller but otherwise essentially 

 similar specimen was collected on the Riviere aux Sables, at Hill No. 4, 

 near Thedford, by the writer in 1891.
