The aperture is broader and pillar fold less definite than in T. 

 fjisiformis (Gld.).

Shell ovately cylindrical, white, shining, very finely striated by 

 the lines of growth, and exhibiting only faint traces of spiral stria- 

 tion ; whorls Ah, the two apical ones forming a small tubercle, the 

 rest somewhat elevated, turreted, and separated by a deeply but not 

 broadly channeled suture ; aperture narrow above, gradually dilat- 

 ing and curved at the base ; the outer lip not extending to the top 

 of the whorl and slightly contracted in the middle; the columella 

 furnished with a stout callus plication, which is connected above 

 with the labrum by a thin callous deposit on the whorl. 



Length 3 lines, breadth 1? lines. {Aug.). 



Dredged outside Port Jackson Heads in 10 fathoms water (Bren- 

 chley).

Shell oval, rounded bluntly in front and sharply above where the 

 papillary apex projects, smooth, augulated above round the outside 

 of the channelled suture, with a strongly toothed twisted oblique 

 pillar, and a smallish mouth, which is shorter than the shell. Sculpt- 

 ure : Longitudinals — there are faint rounded furrows on the lines of 

 growth. Spirals — on the upper part of all the whorls there seem to 

 be close-set very faint spirals ; about the middle of the whorl they 

 become stronger, like very fine remote furrows; a bluntly angulated 

 keel projects axially below the suture. Colour translucent white. 

 Mouth a good deal shorter than the shell, conically elavate, slightly 

 curved, a little blunt at the top. Whorls 4 to 4?, angulated above ; 

 each rises distinctly above the one which follows. Outer lip almost 

 appresed above, but separated by the deep sutural channel which 

 runs into the top of the mouth ; in front it is very patulous, and 

 obliquely truncate backwards, in the middle it is slightly contracted. 

 Top : the whole upper part of the shell contracts and the spire is 

 roundly conical and subscalar, with the glossy round papillary apex 

 rising slightly above all ; it is scored with the sutural canal, which 

 is narrow and not deep, but well defined by the sharp keel which lie& 

 below it. Inner lip ; there is a thick prominent labial pad ; the
