He also remarked the abundance of the beautiful fresh water 
Zoophyte Plumatella repens, which is found in both habitats 
of the Planorbis, and on the dead branches of which it seems 
to find its favourite food. Mr. Rogers said that since the 
year 1869 (when the mollusk was found in small quantity) 
it had increased its area of distribution, and multiplied so 
much as likely to become one of the commonest of our local 
shells.
