 having at its upper part an obtuse yellow keel, regularly attenu-

 narrow, slightly channeled anteriorly ; parietal plaits two, deep, 

 approximate, separated by a deep sinus from the columellar

Shell subrimate, biconical, rather solid, slightly striated and 

 shining, white; spire conoidal, acutely mucronate ; suture linear; 

 whorls ten, the upper ones flat, distinctly striated spirally, the 

 last forming nearly three-fourths of the total length, marked 

 with very indistinct spiral striae, excavated near the suture, 

 then obtusely angled, regularly attenuated towards the base, 

 which is compressed; aperture nearly perpendicular, oblong, 

 rounded in front ; parietal plaits two, the upper one lamelli- 

 form, entering, the other immediately below, obsolete ; colu- 

 mellar plait high, rather horizontally projecting outwards ; pe- 

 ristome acute ; right margin angidated above, bearing within
