sesses two rows of tubercles, there is little fear of confounding 

 with it. The spots here are transverse, which is rather a

Testa turrito-subulata, albida, flammeis atro-fuscis longi- 

 tudinalibus ornat&; anfractibus planulatis, lineis duabus 

 impressis divisis, infra suturam tuberculatis ; area inferiore

Shell subulate, turrited, white, with richly coloured dark 

 red flames, occasionally confluent ; whorls about twenty, flat, 

 above with a girdling line, a second often invisible on the 

 inferior portion of the whorl or in the upper ones, upper part 

 with coarse tubercular folds, becoming nearly smooth below; 

 last whorl banded. Aperture square ; columella twisted ; 

 canal reflexed. 



The whorls, particularly those of the spire, are divided into 

 three spaces by two girdling lines ; the lower area is smooth, 

 but the two others, particularly the most superior, is tubercled. 

 It is a handsome species, from the deep reddish-brown flames 

 with which it is covered.
