Drillin.'] GASTROPODA. 479 



Colour purplish-brown ; inside of aperture brownish. Spire acute, 

 high, turriculate. about 1| times the height of the aperture with canal. 

 Protoconch of 2 smooth convex whorls. Whorls about 10. narrowly 

 shouldered, convex below the angle of the shoulder ; base contracted. 

 Suture bimarginate, not deep. Aperture pyriform. lightly channelled 

 above, produced below into a short widely open and somewhat 

 recurved canal, notched at its base. Outer Up convex, slightly con- 

 tracted below, fairly strong, sharp, cremilated by the spiral sculpture, 

 the sinus situated at the shoulder of the whorl, narrow and moderately 

 deep. Colmnella subvertical, lightly convex at the middle, oblique 

 below. Inner lip smooth, narrow, drawn out to a fine point towards 

 the left margin of the canal, very thin upon the lightly excavated 

 parietal wall. Operculum small, oval, both ends sharply rounded, the 

 nucleus apical. 



Diameter, 10-25 mm. ; height, 28 mm. Angle of spire, 28.

Shell fusiform, turriculate, rather thin and fragile, with strong 

 nodulous axial costse, spirally lirate. Sculpture consisting of about 9 

 broadly convex nodulous axial ribs on a whorl, not extending over the 

 depression of the shoulder, and vanishing entirely upon the base ; a 

 slight spiral thread margins the suture below, 2 to 3 spiral liree cross 

 the ribs on the spire-whorls, the base with strong spiral lirse, which are 

 getting finer and more dense as they approach the neck of the canal. 

 Colour yellowish-brown. Spire high, turreted, acuminate, its height 

 very little more than that of the aperture with canal. Protoconch 

 smooth, mammillary, of 1^ volutions. Whorls 7, with a narrow con- 

 cave shoulder, flatly rounded below ; base contracted. Suture lightly 

 impressed, margined below. Aperture pyriform, lightly channelled 

 above, produced below into a short narrow canal, somewhat recurved 

 and turned to the left, not sinuate at the base. Outer lip convex, 

 contracted below, thin and sharp or thickened and varicose by a rib, 

 with a moderately broad shallow sinus in the depression of the shoulder. 

 Columella slightly convex, turned to the left below. Inner lip not 

 thick, narrow, spreading thinly over the excavated parietal wall. 

 Operculum unknown.
