witli the lirae. Varices nine, compressed, elevated, transversely 

 striated, and crenulated by the lir^e which pass over them. 



Aperture narrowly oblong ; outer lip lirate within, lirae con- 

 tin ued to the margin, which is crenulate ; inner lip widely ex- 

 panded and subreflected. 



Length, 19 ; breadth, 7 ; length of aperture and canal, 8. 



Locality. — Clayey green - sands, Adelaide bore. Three 

 examples. 



3. Epidromus Tasmanicus, Johnston. Plate xi., fig. 11. 



Triton Tasmanicus, E. M. Johnston, Proc. Roj. Soc, Tasm. 

 for 1879, p. 33. 



"Shell narrow, turreted, with elevated spire, and round blunt 

 apex ; whorls eight, cancellated and ornamented with about 24 

 fine riblets and two broad round distant varices on each whorl, 

 which become slightly granulose at points where intersected 

 by the more faintly raised regular carinse, six of the latter 

 visible on the upper whorls ; interspaces, varices, carinas, and 

 riblets finely transversely striate throughout ; aperture entire, 

 ending in a short canal ; outer denticulate interiorly. Long, 

 about 22 mil., lat. 8. Table Cape."— E. M Johnston. 



This species is only known by the unique specimen and now, 

 unfortunately, much reduced in size by fracture, which I have 

 figured. However, from what is left of it, and from the des- 

 cription drawn up before mutilation, it is clear that it is an 

 Mpidromus and specifically distinct from its congeners in the 

 Australian Tertiary beds. The large hemispheric apex with 

 its depressed tip is comparable only with that of JE. texturatus, 

 whilst its rounded whorls and simpler ornament distinguish it. 



4. Epidromus citharellus, spec. nov. Plate iv., fig. 6. 



Shell turriculate ; whorls six (apex unknown), nearly flat, 

 ornamented with thin, elevated, slightly curved, transverse 

 cost£e (16 on the last whorl), the much wider concave inter- 

 spaces distantly spirally striated ; varices eight, irregularly 

 disposed ; outer lip lirate within. 



Length, 18 ; breadth, 5'5 ; length of aperture and canal, 7 5. 



Locality. — Lower beds at Muddy Creek f J". Bennantl) 



5. Epidromus leptoskeles, s'l^zc. nov. Plate iv., fig. 10. 



Shell with a narrow lanceolate outline of eight whorls ; 

 surface ornamented with slightly curved numerous transverse 

 flat ribs. The wider interspaces are divided into oblong de- 

 pression by regular, thick spiral lines. In other respects the 

 species is like LJ. tenuicostatus. 



Length, 14 ; breadth, 14. 



Locality. — Lower beds at Muddy Creek (J. Dennant !)
