This would seem variable both in form and marking. One 

 specimen shows a leaning to M. paucimaculata Angas, another 

 is almost marked as M. theskela M. & S. It is, however, far 

 removed from this latter species. Rude in contour, five 

 whorled, obliquely angled, coarsely ribbed longitudinally, 

 and closely but indistinctly lirate transversely. In shape, 

 elongate fusiform, mouth oblong. Sinus ample and deep, outer 

 lip much incrassate, both it and the columella are many 

 denticled, outer lip but not the columella tinged with fulvous. 

 A few specimens of somewhat varying shape and size. (OdXepos 

 blooming, genial).
