FAMILY 5. PLICACEA. 147 
lusks differing most essentially both in their organization and habits. 
They were then distinguished by Lamarck with the generic title of Torna- 
tella, whilst De Blainville included them with the Pedipes, a genus of air- 
breathing mollusks of the family Auriculacea. The arrangement followed 
by the learned author of the ‘ Manuel de Malacologie’ was scarcely better 
than that of his predecessor Bruguiére ; he, however, cautiously aban- 
doned it when the propriety of Lamarck’s distribution of the Tornatellz 
was subsequently confirmed by Gray in the discovery of their being 
operculated. 
The shell of Tornatella may be described as being oval, cylindrical, 
generally striated transversely, and having a short spire, always sharp at 
the apex ; the aperture is longitudinal, narrowed towards the upper part, 
and entire and rounded at the lower; the columella is thickened and 
strongly plaited, and the lip is simple, solid and acute.
