Shell fusiform; spire narrow, elevated; whorls convex, angulate 

 at the periphery, longitudinally costate, and closely spirally 

 lincate ; costse broad, rounded, from 8 to 10 on the penultimate 

 whorl ; aperture pyrifortn, opening in front to the broad, long, 

 anterior canal; outer margin thin, simple, striate within ; columella 

 with two plications. 



This species differs from F. decipiens in the mode of development 

 of the longitudinal costse, in minor details of ornament, and in 

 having a comparatively straight columella and canal. It cannot 

 be classified with Fusns, because of its columellar plications. 



Dimensions. — Length 26 mm.; breadth 11-5 mm. ; length of 

 aperture 8 '5 mm. 



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

 or three small oblique plaits anteriorly ; sometimes umbilicate ; 

 anterior canal rather long. 



LafArus differs from Peristernia (in which the majority of the 

 species of Latirus here described have been included by Australian
