2 THE NAUTILUS. 



small Planorbis. Often large areas of prairie, inundated during the 

 spring, are covered with these dead shells, which are the ' land " 

 shells of the novice. 



Soon after my arrival in Manitoba, I received a good deal of assist- 

 ance from the Rev. George W. Taylor, of Gabriola Island, B. C., 

 who kindly furnished me with lists of the species he had taken here 

 in 1893, during a flying visit; also any other records or lists of 

 Manitoba species that he knew of. 



The lists furnished were as follows : 



His own from Winnipeg in 1893. 



Condray's, also from Winnipeg. 



Hollands', from Norquay, Man. 



Bells', \ 



Christy's, > all from Winnipeg eastward. 



Daw son's, ) 



(The species taken by Condray and Holland being in his own -ol- 

 lection.) 



All these records are included in the subjoined list. Dr. V. Sterki, 

 Mr. Ed. W. Roper, Mr. Jas. H. Ferriss and others, have kindly 

 helped in the identification of the more troublesome things of my own 

 taking. The numbers before the land shells (following Mr. H. A. 

 Pilsbry's valuable catalogue), show that our local or provincial spe- 

 cies are few and far between. 



(47. Acanthinula harpa Sav.) This species has been taken along 

 the north of Lake Superior, both West as well as East, and I feel 

 sure is to be found in the northern unexplored parts of the province. 

 48. VaUonia pitlchella Mull. (Condray, Holland, Taylor, etc.) 

 50. VaUonia costata Miill. Taken here under stones, etc., along 

 railway banks. 



(Dr. Sterki remarks of these cosfata, "a beautiful and interesting 

 form with rather crowded ribs.") 



53. VaUonia gracilicosta Reinh. Winnipeg in 1893, by Taylor. 



180. Strobilops labyrinthica Say. (Christy and Holland.) 



186. Bijidaria artiiifera Say. Very rare here, also taken by Tay- 

 lor. A rather small form occurs at Brandon; very few were taken. 



187. Bijidaria contracta Say. From Carberry, by Christy. 



188. Bijidaria hohingeri Sterki. Rather plentiful here in the 

 Spring of 1894 in Red River drift. Also taken by Condray and 

 Taylor.
