THE HAMILTON ASSOCIATION. Ill 



greatly assisted by Mr. George Leslie, a large addition has been 

 made to our list of Shells for the district. Mr. Alexander has also 

 made extensive additions to the Herbarium. In addition to the 

 series of notes by Mr. Yates, presented from time to time, many 

 other papers and items of interest have been brought forward, nota- 

 bly a paper by Mr. J. B. Turner on the Anatomy of Birds, and one 

 on Comparative Forms of Animal and Vegetable Life, by Mr. A. E. 

 Walker. During the coming summer it is expected that good work 

 will be accomplished, and as many field days as possible will be 

 organized in addition to the other work that may be done. 



REPORT ON CONCHOLOGY. 



Since May ist, 1890, the following species have been added to 

 the Hamilton List : — 

 ZoNiTES INTERTEXTES, Biruiey. 



Taken by Geo. M. Leslie, May 24, 1890. 

 ZoNiTES MULTiDENTATUS, Biiiney. 



Taken by Mr. A. W. Hanham, Nov. 6, 1890. 



ZONITES FERRUS, Morse. 



Taken Nov. 6, 1890, by Mr. Hanham. 



ZONITES BiNNEYANNUS, Morse. 



Taken by Mr. Hanham. 

 Helix pulchella var. costata. 



Taken April 21st, 1891, by J. H. Lemon. 



LlMN^A COLUMELLA (?) 



Taken by Mr. Hanham. 



LlMN^A REFLEXA, SAY. 



Taken by Geo. M. Leslie. 



LiMNiEA . 



Two specimens of a LtJiincea, taken by Mr. Hanham, are likely 

 to prove new. 



Considering the small number of collectors, this is a good 

 showing for one year's work. 



The taking of Helix pulchella Var. costata is of much import- 

 ance, as I think this is its first appearance in Canada. 



Besides the finding of these new species much other work has 

 been done.
