The specimens are more coarsely sculptured than in Reeve's figure, which was drawn 

 after the unique specimen, as however the Siboga-specimens are more or less variable in this 

 respect, I think it is unnecessary to give them a varietal name. One specimen from Stat. 3 1 3 

 agrees in sculpture, but is somewhat doubtful, as being in no good condition. The species has 

 not been described in Journal de Conchyliologie 1857, as Reeve and Tryon state, the latter 

 with the right page-number of Proceedings Zool. Soc. Lond.

Shell small, subcylindrically subulate, dark yellowish-brown, with upper part of ribs 

 whitish. Upper whorls wanting, remaining whorls 7, but may have been nearly the doublé, if 

 one considers the subulate shape ; whorls nearly straight, only slightly convex, separated by a 

 deep suture, with slightly curved ribs, 18 on last whorl, divided at the upper part by a groove, 

 consisting of a row of conspicuous punctures between the ribs, but scarcely affecting the ribs 

 themselves and with 4 impressed spiral striae on each whorl, conspicuous between the ribs and 

 at their sides, but very weak on their crests; about 12 spiral striae on last whorl, of which S 

 crossed by the ribs, the interstices of the basal ones having more the character of granular lirae, 

 are not ribbed. Aperture elongate, angular above, with a sinus formed by the body whorl and 

 infrasutural belt; right margin obtuse, columellar side with a strong layer of enamel, its interior 

 margin with two folds, canal short, divided by an oblique rib, closely striated above and below 

 it. Interior of aperture smooth, brown. Basal sinus narrow. 



Alt. n 1 /,, (may have been 19 or 20), lat. 2 8 / 4 ; apert. alt. 3, lat. i 1 /^ Mill. 



This species is nearly allied to T. exigua Desh., but is much more cylindrical in shape, 

 moreover the subsutural belt is spirally striated in that species, quite smooth in the new one,
