rounded, very conspicuous cinguli, wliicb, in crossing the ribs, form 

 prominent, smooth, white, oblong beads or nodules; there are three 

 rows of these on the whorls of the spire, and five or six on the body- 

 whorl, the second and third below the suture being more prominent and 

 farther apart than the others. Oinguli without nodules continue to the 

 end of the canal, the transverse ribs disappearing at its base. Aperture 

 a little more than one-third the length of the shell, narrow-ovate, pinched 

 up anteriorly into a very narrow, short canal ; outer lip thickened, form- 

 ing a slight varix, with a thin, white edge and a shallow sinus, close to 

 the suture, with one or two minute white crenulations just within its 

 posterior edge ; there are also about five similar but much larger crenu- 

 lations on the inner margin of the lip, extending from the sinus to the 

 base of the canal. Inner lip continuous with the outer, with a free, 

 thin, white edge, having four or five minute white crenulations just 

 within its inner margin. Canal short, narrow, bent slightly backward 

 at its anterior end, with a decided, but shallow, notch. 



Color of dead specimens, in alcohol, light brown ; when dry, dirty 

 white. One fresh specimen has a light brown, lamellose epidermis. It 

 may belong to Fisania. 



Length of a specimen with imperfect nucleus, 5^^ ; its breadth, 2.5""" ; 

 length of aperture, 2.5™™ ; its breadth, 1™™.
