diameter, that may possibly be referable to this species. Its venter 

 however, is very narrowly rounded rather than carinate, but the venter 

 of the type of Sphenodiscus Maiidensis would be better described as 

 obscurely subcarinated than as inconspicuously carinated. The sutural 

 line of this latter specimen, as represented on Plate 22 of this volume, 

 seems to be more like that of Desmoceras than of Sphenodiscus.

These are precisely similar to the specimens previously collected by Mr. 

 Richardson and Dr. Dawson. They are all more or less crushed, distorted 

 and badly preserved casts of the interior of the shell. Their identity or 

 otherwise with 7'. cylindraceus is consequently very uncertain, and it 

 would probably have been better to have distinguished them provisionally 

 by a different specific name, such as T. Skidegatensis.
