Land and Freshwater Shells. " The Young Collector." By J. W.

Williams, J. W. Taylor, and W. Denison Roebuck. (Swan, Son- nenschein.)—This is a capital little guide to "Shells." A great deal of the space is devoted to the anatomy and physiology of the snail, and some to that of the mussel. The list at the end is very complete, though the blanks that exist in some counties should spur young collectors to great efforts. It is a good shilling's-worth and more than keeps up the reputation of the series.
