Anatomy and Development. 
The important and elaborate work of Graif (6) has resulted in a new 
arrangement of the rhabdoccelous Turbellarians ; after a detailed account 
of the anatomy and physiology of the group, there are chapters on 
cecology and chorology. In the introduction to the classificatory portion, 
the views of earlier authors are compared, and there is a discussion as to 
the value of the systematic characters, and some notes on the variability 
of the species.
