pt. 3, pp. 3-112.

Manuals. 
P. Fischer has commenced a very valuable Manual of Conchology in 
French. The first three parts, published in 1881, discuss the general 
anatomy and physiology of the Mollusca^ including the composition and 
growth of the shell, and also (at great length) the geographical distribu- 
tion ; the author admits 18 geographical provinces for the marine and 
30 regions for the land and fresh-water Mollasca, and illustrates them
