The granulation of the upper surface of this shell terminates 

 abruptly at the periphery, the lower half of the whorl being 

 covered with a very glossy periostracura, marked with fine 

 lines of growth and very fine concentric stri^. The aperture 

 is livid purple-brown within, excepting the whitish base. The 

 pale central zone is not very conspicuous in the specimen 

 from Kapaur, and is situated just above the periphery.

The specimen examined is apparently of a lighter colour 

 than those previously described, the upper part of the spire 

 being light brownish and the rest of the surface paler and 

 clothed with a yellowish-olive epidermis. I am not quite 

 sure which of the above names has priority.

The specimens from this locality differ from the typical 

 form from Andai in having the spire slightly less elevated 

 and the keel more pronounced and compressed. Nanina 

 tritoniensis of Le Guillou, as determined by Canefri, appears 

 to be the same as this variety. The identification seems, 

 however, somewhat doubtful, for the height (23 millim.) 

 given by Le Guillou far exceeds that of the present form, 

 taking into consideration the difference in diameter.
