10 JONES : MOLLUSCAN ALBINISM. 
living with albinos is significant, but on the original cause I do 
not care to speculate. In the Reddish canal last year Bythinza 
tentaculata was taken in many cases abnormally light in colour. 
The specimens ran, in fact, through every shade from normal 
to real albinos. 
I now append a list of the albino shells taken last 
year by the members of the Manchester Branch. To make 
the list more complete, those which have been taken in the 
present year have been added. Such varieties as wtvina of ZH. 
excavata and viridula of H. alliaria, are included as at any rate 
the nearest approach to albinism in those species. 
Those specimens taken in 1894 are marked with an 
asterisk.
