rolulioii covering more than lialf the shell: aperture ex¬ 
actly oval; the outer-lip even; inner-lip a little reflected, 
and forming a slight longitudinal groove behind it: length 
the eighth of an inch ; breadth half as much. 
It differs from the last, in the small groove behind the 
pillar, and its greater proportional breadth : from T. Ulvre, 
in having fewer and much more tumid volutions : and from 
both, in the aperture being exactly oval, and not contracted 
into a sharp angle at the upper end. From T. ruber it 
also differs, in color, in the more oval aperture, and its less 
slender outline.

Shell conic, taper, rather pointed, semitransparent: 
spires six, very little raised, obscurely striate transversely, 
marked with alternate hands of horn-color and cliesnut- 
knvn, generally three of each on the larger volution, and 
two on the rest, the terminal ones obsolete and of a paler 
color: aperture somewhat oval, contracted at the upper 
end; the outer-lip thin and even ; inner-lip a little thick¬ 
ened, hut not reflected: the old shells arc not visibly stri¬ 
ate : length above the eighth of an inch ; breadth a third 
of its length. 
It differs from T. unifasciatus, in being of a more slen¬ 
der form, in the spiral striae observable in perfect speci¬ 
mens, in the brown bands being darker with the interme¬ 
diate spaces not so white, and in having the pillar-lip not 
in the least reflected.
