1. Helicarion SophijE, Gaskoin. 

 (Plate XX. Figs. 8-9). 



Originally described by Gaskoin in Proc. Zool. Soc, 1854, p. 152, 

 us Helix Sophice. 



Figured in Reeve's Con. Icon. Vol. II. Helix, pi. 196, fig. 1377, 

 as Helix Sojihice. 



Nanina (Hemiplecta) Sophice in PfeifFer's Nomenclator Heli- 

 ceorum viventium (sub-section Ecarinatae), p. 49, 1881. 



Figured in Tryon's Manual Conch., Pulmonata, pi. 16, fig. 26, 

 Yol. II. ; description at p. 83 as Nanina Sophice. The figure of it 

 as given here is much too conical.

This is a true Helicarion and not a Nanina ; the animal now 

 figured is not entirely retractile within the shell, and the posterior 

 end has a large dorsal piojection and mucous pore.
