 Bulimulus (Liostracus) manoeli CLESSIN, Mai. Bl. 1888, p. 166. 



Very variable in the amount of purple or reddish streaking and 

 suffusion above, this species seems to constantly have two purplish 

 bands, invariable in position but showing some variation in width. 

 In some shells there is a wide obscure zone above and adjacent to 

 the peripheral band, and ascending the spire. It is named in honor 

 of a Creole who assisted Blanchet to collect natural history specimens. 

 Fig. 24 was drawn from a specimen received from Moricand. 



There is a later Helix manoeli of Pfeiff'er, which is a synonym of 

 Plexrodonte (Labyrinthns) manueli (Higgins).
