Belly Elver, east side of Driftwood Bend, — and South Saskatchewan, 

 six miles below the mouth of Bow Elver and thirty-five feet above the 

 water level ; G-. M. Dawson, 1881 . a few more or less perfect speci- 

 mens from each of these localities. Xorth side of Milk Elver, five miles

 examples. 



Some of the specimens from the Belly Eiver show the "slight angu- 

 larity at the distal >ide of the larger volutions" indicated in Dr. White'.s 

 latest figui'es of the species and his explanations thereof, but those from 

 the South Saskatchewan are more like the type originally figured hy 

 Meek and some are very near in their character to C. vetula, which, 

 however. Meek thought might be a mere varietv of C. multilineata.
