 growth; base spirally ridged and transversely wrinkled." — Tate. 



It may be compared with the living T. mariesi, E. A. Smith, of 

 Japan.

Neither of the specimens in the Museum presents a perfect 

 protoconch, but Professor Tate remarks that it consists of " a 

 relatively large papillary pullus of two turns ; the first turn of 

 the pullus subglobose, with the tip reverted and immersed, much 

 broader than the next two or three whorls." The sutures of the 

 shell are slightly canaliculated and distantly bordered by a linear 

 sulcation ; the whorls are ornamented with transverse curvilinear 

 ridges and a few indistinct spiral striae most conspicuously de- 

 veloped in adult specimens. 



This species has considerable analogy with certain European 

 Miocene forms of Terehra — in particular T. perhisa, Lamarck, 

 from the Langhian beds south of Bordeaux. It is narrower than 

 that species, however, and the whorls are flatter and more turri- 

 culate. It is allied also to the living T. cingulifera, Lamarck, 

 from the Philippines, China, etc. 



Dimetmons. — Length 40 mm. ; breadth 5 '5 mm. Professor Tate 

 states that the largest examples attain to 60 mm. in length. 



Form, and Loc. — Eocene : Muddy Creek, Victoria.
