LAND AND FRESH WATER SHELLS IN THE ROCKY MOUNTAINS. 
BY GEO. W. TAYLOR, VICTORIA, B. C. 
In the October Nauriius there is a short paper by my friend 
Mr. Hanham upon the shells found by himself during a trip in that 
rather out of the way Canadian locality, the Gaspé region. 
It may be interesting to have a record of a small collection made 
by me a few weeks ago in another little-known locality at the oppo- 
site end of the Dominion viz.: Laggan near the summit of the Rocky 
Mountains. 
I had received earlier in the year from Mr. T. R. Bean of Lag- 
gan, anice little collection of shells which included specimens of 
what Dr. Sterki considers to be the true Pupa hoppii of Maller, 
and this tempted me to stay over for a couple of days when passing 
through Laggan last September on my way to Toronto. 
Dr. Bean most kindly showed me all the best localities known 
to him, and our united exertions were rewarded by the discovery of

which I believe had not before been found in Canada. 
In the rivers, the Bow and the Pipestone, we could not find any 
shells at all, the waters being cold and the stream rapid in each case, 
but in all the little creeks and swamps Linnea palustris abounded
