The Kohelti of Rolle is a pale yellow specimen without the 

 dark purple-brown bands. Martens's subconcolor is near 

 Koheltij but narrower, and with two very faint yellow bands 

 encircling last whorl, which are not shown in the figure. 

 This species varies very much in its colour-banding ; but 

 even in the very pale varieties, where the dark-coloured 

 bands are wanting, one can trace the characteristic pale 

 orange-yellow lands that encircle the whorls.

Loc. Celebes ; Moluccas. 



This species and its varieties may be always distinguished 

 by the characteristic dark spots upon the whorls ; in the light- 

 coloured varieties the spots are semitransparent when held 

 before the light.

The type specimen is in rather poor condition ; when 

 fresh this species is ornamented on the last one and a half 

 whorls with close-set oblique bright green stripes, sometimes
