This species differs from T. maccoyi, Tenison-Woods, in being 

 relatively narrower, the spire is much higher, it is not so 

 prominently spinose, though the varices bear several minute frills 

 which curl round, forming short tubules, leading up to which 

 on the whorls are some oblique costae. The intermediate tube 

 is very near the suture, and is larger thun any of the others. 

 The aperture is ovate, and the plate affixed to the columella rises 

 high, as in T. horridus, of the Italian Miocene.

Much smaller than any of the preceding species of Typhis, from 

 which it may readily be distinguished by the plainer character 

 of the ornament on the whorls. It is solid, not distinctly varicose, 

 though there are frequent breaks in the growth. Between each 

 of these latter the whorls rise into a curved, obtuse, plain, 

 longitudinal ridge, on the crown of which is a large, blunt, 

 recurved, flattened tubule, completely covering the suture though 

 detached from it. The suture may only be observed between 

 these large tubules, and then not very distinctly. The protoconch 

 is of the same character as in T. maccoyi; aperture very small, 

 almost circular, canal quite covered in. 



It is of the same general type as T. Jistulosus, Biocchi, of the 

 Italian Tertiary and of our own Barton Beds, but the spire in 

 the Australian species is more elevated, it is minus the leaf-like 

 expansion ou the outer margin of the aperture, and it has not the
