 Inhabits the coasts of Guinea. Chemnitz, 

 Shell about an inch and a half long, and nearly half as broad, 

 of a pale chestnut-colour ; the beak is short and obtuse, and 

 the pillar somewhat umbilicated ; the outer lip is sinuated by 

 a notch at its upper extremity. M. Taxus, as it is figured by 

 Chemnitz, has rather the appearance of being an accidental- 

 ly distorted shell, and though it answers to many of the lead- 

 ing characters of this species, may possibly belong to some 

 other.

 plaits and transverse grooves, and an elevat- 

 ed belt at the sutures ; outer lip with a notch 

 at the summit, and the beak short and ob- 

 tuse.
