fine, smooth, median carina. On the body-whorl the ribs continue 

 nearly to the base of the canal and are crossed by small, nearly 

 smooth, rounded, equally distant cinguli, which commence a little be- 

 low the third principal carina and continue to the end of the canal. 

 The entire surface is covered with very minute, microscopic granules. 

 Aperture narrow-ovate, pinched up anteriorly into a short, rather 

 narrow, straight canal. Outer lij) very much thickened, witli a con- 

 spicuous varix, and a tliick, smooth, rounded, very irregularly curved, 

 light brown edge, and a deep, narrow sinus considerably below tlie 

 suture, at the angle of the shoulder; inner lip inconspicuous; colu- 

 mella slightly curved. 



Color yellowish white, tinged with brown just below the suture, 

 and on the anterior part of the body-whorl.

This species, although closely resembling the preceding, is sufficient- 

 ly characterized in haviug a much stouter form, more acute apex, 

 more angularly shouldered whorls, fewer and more prominent ribs, 

 more numerous cinguli, and especially in having its entire surface 

 microscopically granulated.

Shell small, semi-transparent, fusiform, with about five slightly 

 convex whorls, below the nucleus, which consists of three and a half 

 smooth, transparent, white, glassy, regularly increasing turns. The 

 apical whorl is small, not very prominent, somewhat oblique. The 

 sculpture consists of about ten rather indistinct, narrow, longitudinal 

 ribs, and broad, rounded, very conspicuous cinguli, which, 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 are the most prominent 

 and farther apart than the first two. Cinguli without nodules con- 

 tinue 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, forming a slight varix, with a thin, white edge 

 and a shallow sinus close to the suture, with one or two, minute, 

 white crennlations just Avithin its posterior edge; there are also about
