Montagu, pl ? 20. f. 3. 
Shell conic, rather elongated, semitransparent, with a 
small but not very pointed tip, generally rufous horn-color 
covered with a very rough wrinkled skin : spires five or six, 
rounded and well defined, with four or five purplish-brown 
or chesnut bands on the body volution* and^a broad space 
between the three which are placed near tlie end and the 
two which are contiguous to the next volution ; sometimes 
the color is paler, and the bands fainter and variously dis¬ 
posed, and sometimes they are altogether wanting: aper¬ 
ture somewhat orbicular, rounded.at the base, margined 
by the outer skin j the ou^er-lip very thin : inner-lip witn 
a narrow groove which ends in a small p erforation: length 
aquarterof an inch; breadth about half as much. 
In all the varieties it may he distinguished from T. cana¬ 
lis, by its size and elongated form, in not having the aper¬ 
ture somewhat angular, and in the groove and perforation 
being comparatively smaller : and from T. quadrifasciatus, 
in being much larger longer and thinner in substance, and 
in wanting the slight carinated ridge at the base of the 
larger volution. Some are also of a greenish cast between 
the bands, and appear finely reticulated when much mag¬ 
nified.
