'This species resembles A. simplex Smith in the absence of 

 colour-markings and in the size of the apical whorls, but 

 differs entirely in its more elongate form. This is particu- 

 larly apparent in the body-whorl and aperture. 



'The above description is based on a single specimen 

 recently presented to the British Museum by Colonel J. II. 

 Bowker. It was collected on the Drakensberg, north of 

 Natal, at an elevation of 5000 to 6000 ft., by Mr. Henry E. 

 Burnup, after whom I have named the species." (Smith). 



The specimen figured measures, length 66.5, diam. 33, aper- 

 ture 36 mm., and has not quite 7 whorls, the first 4 denuded 

 of cuticle and flesh-colored, the next 2 beautifully decussate ; 

 while fine, nearly obsolete spiral lines are barely trace- 

 able on the last whorl.
