A special feature of the evening was the exhibition by Mr. Ed. Collier of his 

 collection of Helix nemoralis, in which the colour gradations incident to locality 

 and change of food, endless combinations of band formulae, as well as curious 

 abnormalities, were shewn to perfection in the extensive series of carefully selected 

 examples gathered together by him during the course of many years. Mr. Collier 

 demonstrated the chief characteristics of the "varieties" acknowledged in the 

 Society's List. 



Mr. T- W. Baldwin also exhibited some curious local varieties.
