The sculpture of this rare shell, of which no example is known 

 in fine condition, reminds one of cumingii ; upon the whole, however, 

 D. variegatum is its nearest congener. As the largest specimen 

 examined by me, although solid, and copiously spread with parietal 

 enamel, had only attained to two volutions and a half (the first of a 

 pinkish cast) beyond its smooth yellow nucleus, I am not sure that 

 it was adult. Its body was encircled by eighteen ribs, in the narrow 

 intervals of the few superior ones of which might be discerned the 

 commencement of a raised stria. Its spire was remarkably short 

 in comparison with the elongated and rather narrow aperture : its 

 contracted umbilicus was almost concealed by the pillar-lip.
