The animal is fragrant. Jickeli placed the single speci- 

 men found, which was closed with a strong, thin, chalky, 

 flat epiphragm, in alcohol. When the epiphragm was broken 

 an agreeable odor, recalling oil of roses, poured out. As the 

 specimen was preserved in the same alcohol with other 

 Subulinas, the fragrance must have proceeded from the animal 

 itself, and not from the alcohol. Examples of ill-smelling 

 land snails are already known (see Martens, Nachrichtsblatt 

 Deutsch. Mai. Ges. 1871, p. 201) .
