The specimen in the Museum is too mutilated for minute 

 description. The posterior portion of the later whorls have a 

 narrow ante-sutural band ; the plications are narrow, slightly 

 bent, and subnodose, and between them are very fine and close 

 reticulations. 



Dimensions. — Length about 9 mm. ; breadth 3 mm. 



Form, and Loc. — Eocene : Table Cape, Tasmania.

The sutural band is not so deeply impressed as in typical 

 specimens in the Museum from Tasmania, as found living, whilst 

 the body-whorl is more convex ; these differences may constitute 

 a variety from which the living forms may have descended, but 

 they are not worthy of specific rank. 



Dimensions. — Length 33 mm. ; breadth 9 mm. 



Form, and Loc. — Post- Pliocene : Limestone Creek, Glenelg river, 

 Victoria.

The protoconch (Plate II. Figs. \a-l) of this species is subacute 

 and composed of three convex turns. The whorls of the shell are 

 much constricted posteriorly, and between the constriction and the 

 suture there is a row of tubercles ; the remainder of the surface 

 of the whorls has distant rugose ribs which are angulate, and 

 the whole presents rather the aspect of certain forms of Drillia 

 than of Terehra. That it ought not to be classified with the 

 Pleueoxomid.^, however, is clear from the general phenomena of 

 the aperture. 



It diff'ers from T. mutica, Tate, from the same locality but of
