HELIX. 53 



collected by myself in 1856. I had but an imperfect knowledge 

 of land mollusks at the time, or I should have seen at once,, as 

 I did some years afterwards, when re-examining my collection, 

 that the shells were all young specimens of Raphaulus Blan- 

 fordi (Jour. Asiat. Soc. Bengal, 211, 1880).
