Shell conoidal, imperforate, transversely sulcate-cingulate, yellow- 

 ish, painted with oblique blood-red streaks; whorls convex, the last 

 scarcely angular ; aperture rhombic-rounded ; columella very 

 oblique^ cylindrical, simple. (Phil.} 



The shell is rather thick,, imperforate, conoidal ; the 6 whorls are 

 convex, the last scarcely angular, with 7 to 8 transverse sulci, which 

 are as broad as the ridges lying between them ; the base is similarly 

 traversed by the same number of sulci. There is scarcely a trace 

 of umbilicus to be seen. The aperture is rhombic-circular, and 

 appears somewhat contracted on account of the very thick lip; the 

 columella is very oblique, cylindrical, straight ; the color is yellow- 

 ish, regularly marked with oblique blood-red streaks.

 smaller one between them, on each side of which is a minute spiral ; 

 base with 5 to 7 concentric lira? ; interstices all over obliquely
