MOLLUSCA.' 
account of the internal structure, biological processes, and classification 
of the Molliiscay and describes the common forms found in or imme- 
diately near London, and peculiar to the chalk of Southern England. 
Hints for collecting conclude the volume. There are many original 
observations on the occurrence and life of individual species, which will 
render the work not only useful to amateurs residing in London, but 
also to those living abroad. Most species are figured, and the figures are 
very good.
