mammillated ; whorls 6, slightly convex, longitudinally ribbed, 

 crossed with spii-al lirse, very conspicuous on the edge of the ribs, 

 finer between and at the sides ; aperture ovate, outer lip rather 

 thick, slightly variced behind ; interior of aperture with three to 

 four small nodules ; columella straight, canal short, curved. 

 Long 6|, greatest breadth 4, least 3| mm. Five specimens, 

 This pretty little shell may be known by the large dark reddish- 

 brown spots below the suture, and nearly on the angle of the 

 whorls. A number of specimens of this species were collected in 

 1866-67 at Green Point and sent to Mr. Angas with a number of 

 the species that are now described in this paper (J. B.).
