and always small ; the spire is exserted. Tn shape it varies from 

 ellipsoid-cylindrical to cylindroid-subpyriform. The outer lip is 

 narrowly reflected, distinctly margined, emarginate but not canal- 

 iculate behind, and provided with about 20 transverse teeth ; the 

 inner lip has about 15 teeth. 



Dimensions. — Length, 15-5 ; width, 8 ; height, 7 (at 5-5 mm. 

 from the posterior end). 



Localities. — Eocene ; Muddy Creek and Schnapper Point. 



10. Cyprsea pyrulata, spec. nov. 



Shell cylindroid-pyriform, inflated posteriorly and gradually 

 tapering to the front ; spire more or less concealed, narrowly but 

 deeply umbilicated, from the edge of which the whorl arises 

 abruptly with a well-rounded curve to tne highest point of the 

 back, which is at about two-fifths the total length from the pos- 

 terior end. Surface smooth or spirally lineate. 



Aperture rather wide, emarginate but not canaliculate behind, 

 extending at the front into a short straight truncated beak. 

 Outer lip narrowly inflected, not distinctly margined, transversely 

 ridged (about 25), much-curved behind and projecting beyond 

 the spire. Inner lip hardly thickened and not at all produced 

 posteriorly, with about 20 dentate ridges. 



Dimensions of two examples. — Length, 27 and 24; width, 16 

 and 13-5; height, 13-5 and 11-5. 



Locality. — Eocene ; Muddy Creek (very common). 



11. Cyprsea Murraviana. spec. nov. 



Shell pyriform, back ventricose, abruptly rounded to the con- 

 cealed faintly-depressed spire, tapering rapidly but not so abruptly 

 to a straight, broadish, very short, truncated beak, which is 

 rounded on the margins. 



Aperture narrow, gently curved posteriorly, the outer lip pro- 

 jecting backwards into a short lobe with a thickened quadrate 

 margin ; there is no anal canal. Outer lip broadly inflected, 

 externally margined, with about 20 narrow tooth-ridges ; inner 

 lip convexly rounded, with from 1 2 to 15 long slender ridges ; 

 columella-plate narro .v, ridged, anteriorly running out in an 

 oblique tooth-like ridge to the extremity of the beak. 



Dimensions. — Length, 20; width, 1-4; height, 11*5 (at 8 •75mm. 

 from the posterior end). 



Localities. — Eocene. River Murray Clifts ! ; near Mount 

 Arapiles, Victoria (J. Dennant). 



This fossil cowry resembles C. lyyridata by its protuberant 

 arched outer lip and the absence of a posterior canal, but differs 

 by^being more ^-entricose in the dorsal profile, more abruptly 

 narrowed at front and by the mucli incrassated outer lip. From
