Inhabits India. Muller, 



Shell about an inch long, and rather more than one third as broad, 

 and in the aperture possesses some affinity with Turbo Uva ; it 

 has nine smooth whirls, of which the body-whirl is almost as 

 long as the others put together ; the aperture is semi-ovate, and 

 has one tooth on the pillar-lip ; Muller probably described a 

 young shell, and has not mentioned this tooth, which Bru- 

 guiere says is always to be found when the shell has attained 

 to maturity ; it is umbilicated, and Gmelin has erroneously 

 placed it among the imperforate species. 



TROCHOiDES. 110. Shell mnbilicated, trochiform, 

 shining, longitudinally wrinkled, with the 

 whirls reversed, and the body-wdiirl keeled ; 

 aperture angulated, and the pillar brown.
