Shell small, narrowly perforate, conoid, obtuse ; whorls 5, convex, 

 separated by linear sutures; the first whitish; the remainder very 

 finely obliquely striate, shining, very variable in color, sometimes all 

 chestnut or blue, sometimes maculated with green or brown and 

 spirally zoned, the bands linear, narrow, pale, sometimes articulated 

 with brown ; penultimate whorl rather tumid, body-whorl angulate, 

 sub plan ul ate below and obsoletely concentrically lirate ; aperture 

 sub rotund, silicate within ; basal margin arcuate ; columella regularly 

 concave-arcuate, nearly closing the umbilical perforation above ; 

 umbilical area somewhat funnel-shaped, white, striate, carinate at its 

 margin. Alt. 6, diam. 6 mill. (Fischtr.)

According to Dr. Fischer, the T. balteatus Phil, differs from T. 

 smaltatus in its more conical form, flatter whorls, and the columella, 

 which is vertical, not arcuate, and subnodulose, forming an angle 

 with the basal lip.

The shell is solid for its small size, perforate, nearly exactly 

 conical in form, and consists of 6 whorls, of which the upper are 

 almost planulate, while the last, which is as high as all the others 

 together, is bluntly angulated ; the upper whorls are encircled 

 around their lower borders by a white girdle articulated with vertical 

 black lines, and which is continued upon the periphery of the last 

 whorl ; above this girdle are 5 elevated transverse lines, and upon 

 the base about 12 inconspicuous ones; the columella is almost 

 vertical, rounded, with a slight tubercle in the middle, and forming 

 an angle with the basal lip: the color is pale brown, and besides 

 the above described girdle has large deep brown inoculations below 

 the suture ; the spiral line are punctate with black ; the base shows 

 oblique streaks, formed by the coalescence of black dots.
