 Turbo canalis. Montagu Test. p. 309- t. 12. f. 11. 



Inhabits the sea near Southampton. Motitagu. 



Shell about three-eighths of an inch long, and a quarter of an 

 inch broad, pellucid, horn-coloured, with five smooth 

 rounded whirls, of which the body-whirl is proportionably 

 large ; the pillar-lip is broad, white, and furnished with a 

 channel or groove terminating in an umbilicus. Mr. Mon- 

 tagu says it has the habit of H. tentaculata, but is at once 

 discriminated by the aperture and groove on the pillar-lip ; 

 it is also a marine, and the other a fresh-water shell. 



LUTEA. 182. Shell imperforate, sub-oval, thickisb, 

 and of a yellowish orange colour ; aperture 

 spreading and oval.

Inhabits the sea-shore in Devonshire. Montagu. 



Mr. Montagu says that this species has somewhat the habit of 

 a young shell of H. auricularia, but that it is less tumid, 

 and though of inferior size, it is always much thicker and 

 stronger; he has thus described it: " H. with a sub-oval, 

 sub-pellucid, moderately strong, smooth shell, of a dull 

 orange yellow colour ; volutions scarcely three, the first ex- 

 tremely large, the others very small ; apex obtuse, not pro- 

 minent ; aperture patulous, oval ; outer lip not attenuated ; 

 inner lip pretty strong, and a little spreading on the colu- 

 mella : length nearly half an inch ; breadth rather more than 

 a quarter." 



AURICULARIA. 183. Shell imperforate, ovate, ob- 

 tuse, with a very short pointed spire; aper- 

 ture much expanded.
