Description. — T. elongato-fusiformi, spira turrita; anfr. ad

Dimensions. — Long. 6, diam. 2 mill. 



Habitat. — Paumotus. 



Shell elongately fusiform, spire turrited ; whorls angulated at

Description. — T. oblonga, subcylindrica, transversim, tenuiter, 

 conferte lirata ; longitudinaliter costata, inferne costis evanidis ; 

 spira brevissima ; anfr. spirte tumidis ; labro incrassato ; apertura 

 breviuscula ; sinu lato, profundo ; canali brevi, lato ; alba, inter- 

 dum liris transversis rufo-castaneis. 



Dimensions. — Long. 8, diam. 3 mill. 



Habitat. — PaumoLus. 



Shell oblong, somewhat cylindrical, light, faintly and closely 

 ridged transversely ; spire very short, the two last whorls com- 

 prising three-fourths the length of the shell ; longitudinally 

 ribbed, ribs obsolete or disappearing altogether on the two last 

 whorls ; whorls five, those of the spire inflated, last whorl rather 

 out of the centre ; sutures well impressed ; outer lip thickened 

 externally ; aperture rather short ; sinus broad and rather deep ; 

 canal short and open ; white, transverse ridges occasionally 

 reddish-chestnut. 



Remarks. — In sculpture and general shape the above species 

 resembles the Daphnellse. The inflation of the whorls of the 

 spire and the extreme shortness of the upper whorls distinguish 

 it. On young specimens the inflation is scarcely perceptible.
