10 on a whorl, extending from suture to suture, but absent on the 
base, crossed by distant and prominent spiral cords, with a few inter- 
calated fine threads upon the neck of the canal, produced into oval 
nodules upon the axial ribs; the spire-whorls with a fine thread below 
the suture, margining it, and 3 distant strong spirals below it; body- 
whorl with 14-15 cinguli, those upon the base not nodulous. Fasciole 
hardly discernible. Colour yellowish-brown, neck of canal and imner 
lip whitish, interior of aperture light brown. Spire acuminate, conic, 
of the same height as the aperture with canal. Protoconch papillate,
