Shell subulate, turrited, heavy, polished, adorned with 

 small interrupted irregular strigse of a rufous colour ; whorls 

 divided by a groove not always very conspicuous, encircled by 

 two series of punctated spots ; columella rather produced, 

 particularly in the older individuals, rather straight. PI. xlii. 

 fig. 32, represents a very pretty variety of this shell from the 

 collection of Sir Edward Belcher, C.B., and which was pro- 

 cured at the Marquesas.

 longitudinalibus irregulariter ornata ; anfractibus planulatis, 

 striis arcuatis incrementi conspicuis, superne sulco impresso 

 divisis ; columella subcallosa, rectiuscula. 



Shell truly subulate, polished, of a flesh colour, sometimes 

 more intense, sometimes paler, interrupted by white strigfe 

 which are occasionally united or broken in their course ; 

 whorls flattish, duplicate, the superior area less occupied by 

 the white strigee ; aperture effuse ; columella somewhat callous, 

 and strait. The character of the ornation is very similar to 

 that in T. strigata.

 lighter individuals are found at Tahiti, and do not appear to 

 affect different localities.
