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 Hying 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 Xorquay, Man. 



Bells', ) 



Christy's, all from Winnipeg eastward. 



Dawson's, ) 



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

 lection.) 



All these records are included in the suhjoined list. Dr. Y. 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 hefore 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. Vallonia pulchella Mull. (Condray, Holland, Taylor, etc.) 



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



railway hanks. 



(Dr. Sterki remarks of these cos/ata, "a beautiful and interesting 

 form with rather crowded ribs.") 



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



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



186. Bifidaria armifera Say. Very rare here, also taken by Tay- 

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



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



188. Bifida i in holzingeri Sterki. Rather plentiful here in the 

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

 Taylor.
