9S COCHL1TOMA. 



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

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

 ;dift'ers 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. H. 

 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.

Shell sinistral, thin, subpellucid, pale ochraceous, oblong- 

 ovate. Whorls 7, a little swollen, longitudinally flammulate 

 with brown, microscopically granulose-striatulate, the striae 

 transverse, the last whorl nearly smooth beneath. Columella 

 lightly twisted, truncate, brown. Aperture oblong, the lip 

 thin. Length 2.35, diam. 1.25 inch. (M. & P.}.

The last whorl appears almost smooth, although the striae 

 are traceable with a lens for some little distance below the 

 suture. 



26. C. SIMPLEX (E. A. Smith). PL 12, fig. 37. 



"Shell rather thin, light ovate, clothed with shining olive- 

 brownish thin epidermis, here and there streaked in an 

 oblique direction with narrow stripes or lines of a deeper 

 shade of the same colour; spire obtusely conical, terminated 

 by a rounded, blunt apex, whorls 6 1 /^> gradually increasing, 

 sculptured by oblique lines of growth, which are granulated 

 on the upper portion of the whorls; the granules are oblong 

 and vanish almost entirely on the lower third part of the
