Shell about an inch and a half in diameter, of a bright fawn- 

 colour, with six slightly convex whirls ; the aperture appears 

 in the figures to be very strangely formed, with a labyrinth 

 of projecting teeth and sinuosities which commence at the 

 umbilicus, and project considerably beyond the contour of 

 the body-whirl. 



PUNCTATA. 28. Shell siib-umbilicated, slightly 

 keeled, roundish ; inner lip thickened and 

 sinuated, and the outer three-toothed.

Shell about half an inch long, and ten lines broad, of a brown 

 colour, with a row of distant yellowish spots in the middle 

 of the whirls ; it is roundish, but slightly depressed, and has 

 five whirls; aperture ear-shaped, contracted, and has the 

 pillar-lip projecting over the umbilicus. Lister's f. 94 is 

 probably distinct, and is the same as Petiver, t. 105. f. 6, 

 and Favanne, t. 63. f. F 3. 



SINUATA. 29. Shell imperforate, sub-globular, and 

 slightly keeled; lip reflected, with four teeth 

 on the inside, and three-plaited behind.
