the upper bases of the tentacles ; in Tomichia the eyes are placed 

 upon tubercles near the upper bases of the tentacles. The 

 foot in Blunfurdia would seem to be somewhat similar to that of 

 Tomichia, being lobed on each side in front and with a posterior 

 dorsal lobe which bears the operculum. Both my species are 

 found on damp banks covered with vegetation, in rocky situa- 

 tions near the sea. 



I have dedicated the genus to my friend W. T. Blanford, 

 who has discovered many new and interesting forms of Land- 

 Mollusks in India.
