' Shell sinistral, inflated, finely striate ; spire conic, acute ; 

 epidermis brown, fugacious; whorls 5y 2 ; suture not dupli- 

 cated; aperture semilunate, white; peristome thickened 

 within; columella white, provided with a distinct rib; an 

 unbilical fissure. This species, which also inhabits the Sand- 

 wich Islands, has especial resemblance to the preceding [vul- 

 pina], but it is more swollen, the spire is more pointed and 

 the sutures are simple. The columella affords more distinctly 

 an elevated rib, revolving around it and penetrating into 

 the shell." (Fer.)
