2o6 The Ottawa Naturalist. (January 



The specimens of U. luteolus are not of so decided a green in 



color as those found in the Rideau Canal and River near Ottawa, 

 and are much more inflated. 



The U. gibbosus are small and differ materially in form from 

 the shell as usually found in the Ottawa River, where it occurs 

 sparingly at the outlet of Brigham's Creek and at the lower end of 

 Duck Island. They are, however, identical with a single speci- 

 men found many years ago in the " chenal " at the Little 

 Chaudiere. This peculiar little shell is the only specimen of 

 U, gibbosus known to have been collected in the Ottawa River 

 above the Chaudiere Falls, 



With the shells obtained by Dr. Fletcher was a specimen of 

 the remarkable spiral caddis-case, which the late Isaac Lea,- -in 

 his time the most prolific writer on Conchology, regarded as a 

 true moUusk, and named Valvata arenifera. Dr. Fletcher, of 

 course, as an experienced entomologist, placed the so-called shell 

 in its proper place.

A NATURAL HISTORY MUSEUM, AT BETSIAMIS, 

 QUEBEC, CANADA. 



The Reverend P^re C. A. Arnaud, of Betsiamis, has estab- 

 lished and encouraged the development of a Natural History 

 collection at this trading post. 



In the year 1868, Alfred Lechevalier, a French Naturalist, 

 visited the post and spent that year and the following winter in 

 mounting the specimens of the fur-bearing animals which he had 

 obtained in that region, and of birds which he had shot the season 

 previous, in different portions of the Great North-East. 



Birds, mammals, reptiles, etc., make up the materials of the 

 Natural History portion of the collection of that Museum, whilst 

 various other kinds of specimens have been added and obtained 

 chiefly from the aborigines who come to the post from time to 

 time. The value of the collection is estimated by Abb6 Huard at 

 $4,000.00.
