sculpture on the earlier whorls of about 18 protractively oblique rounded 
ribs, slightly angulated at the shoulder, feeble on the fasciole and crossing 
the whorls except on the last whorl where they gradually become obsolete; 
the whole surface is spirally sculptured with fine close-set threads; here 
and there one a little more prominent than the rest, others near the canal 
coarser; anal sulcus wide and shallow; outer lip arcuate, inner lip erased; 
canal moderately long, slightly recurved. Height of shell, 15; of last 
whorl, 11; diameter, 6 mm. (Dali.)

Shell fusiform, moderately thin, six whorled; whorls rounded, suture 
distinct; sculpture consisting of (on the last whorl) 23 stout, uniform, 
slightly flexuous rounded ribs extending from the suture to the canal with 
slightly narrower interspaces; lines of increase distinct; sometimes thread¬ 
like ; these are crossed by numerous close-set spiral threads; separated by 
narrow grooves, both faint near the suture; threads growing stronger, 
regularly wider, and coarser gradually toward the canal, near which they 
are stronger than the obsolete ends of the transverse ribs; anal fasciole 
(notch band) indistinct, aperture narrow, elongated with an acute posterior 
angle, outer lip thin, columella simple, canal rather wide; shell whitish, 
with a reddish tinge anteriorly, especially on the last whorl; interior of 
aperture reddish, of the canal pure white. Long, of shell, 17; of last 
whorl, 12.5; of aperture, 10; lat. of shell, 8; of aperture, 3.5 mm. (Dali.)
