 three dark l)rown spiral color hands, of which the posterior two show 

 strongh" upon the spire of the last three whorls;

 the whorls a little posterior to the middle between 

 the sutures. The middle one is the broadest; it 

 is situated immediately aboye the periphery, being 

 completely exposed aboye the suture; the basal 

 one, which is about half as wide as the peripheral 

 band, encircles the base a little posterior to its 

 middle. The white columella is strong, straight, 

 and broadly expanded and reflected at base. 



The t3'pe has six and one-eighth whorls and 

 measures: Altitude, 23 mm.; greater diameter, 

 11.5 mm.; lesser diameter, 10 mm,; aperture alti- 

 tude, 12.8 mm. The type was collected by Prof.
