After a protracted examination we have decided upon 

 uniting the Auricula myosotis of Draparnaud to the 

 Voluta denticulata of Montagu. As many conchologists 

 will dissent from this conclusion, we have scrupulously 

 kept apart their description and synonymy. The follow- 

 details pertain to the marine form denticulata. 



Shell of a conical-oblong or oval shape, more or less thin 

 and transparent, pale yellowish brown umber or horn- 

 coloured, more or less faintly wrinkled lengthways, obso- 

 letely subplicated, and in living specimens finely ciliated 

 beneath the distinct yet simple suture. Spire varying 

 greatly as to height, usually elongated for the genus, in the 

 narrower examples often much produced, composed of 

 from six to eight turns, that are of rather slow longitudinal 

 increase, are well defined from their decided convexity, 

 and taper above ; apex moderately small, unsymmetrical. 

 Aperture occupying fully one-half the length, oblong-lan- 

 ceolate, narrowly rounded below, gradually contracted 

 above to a curved and very acute angle ; toothed on both 

 sides. Outer lip more or less arched, strengthened inter- 

 nally at a little distance from the acute and somewhat
