Shell fusiformly ovate, with a somewhat high scalar spire, 

 terminating in a small obtuse apex consisting of two smooth 

 whorls. Whorls seven, of which those of the spire, excepting 

 the two apical ones, are quadrate, the slightly upward sloping, 

 posterior area about equalling in breadth the anterior part ; 

 last whorl sharply angulated postmedially. Varices seven to a 

 whorl, thinly lamellose, narrow, often obsolete on the posterior 

 area, which at the angle project into short hollow, slightly 

 backward curved spines ; on the posterior whorls they lose their 

 lamellose character and become simple costse, and finally devoid 

 of spines. 



The spiral ornament consists of slender equidistant threads, 

 on the last whorl six occupy the posterior two-thirds next 

 suture, those anterior to the angulation are stouter, nearly as 

 wide as the intervening furrows. A rather broad space on 

 either side of the angulation is devoid of lirse, but is closely 

 finely spirally striated. 



The transverse ornament consists of rather crowded lamellse, 

 which are raised into depressed, roundly arched, vaulted 

 scales on the lirse. 



Aperture rhomboid-ovate, angulated at the keel, outer lip 

 thin with a crenulated edge. Canal open, about as long as the 

 aperture, sinistrally arched, and somewhat recurved. 



Length, 22 ; breadth, 10'5 ; length of aperture and canal, 14.
