4. Cyppaea ampullaeea, spec. nov. 



Shell elliptic-oval, highest and widest a little behind the middle ; 

 obtusely rounded apically with a very narrow, flat, exposed 

 spire ; gradually narrowed to the front ; surface transversely and 

 spirally lineate, the small rectangular interspaces contusedly im- 

 pressed. 



Aperture moderately wide ; slightly curved and obsoletely 

 notched posteriorly ; extended into a short straight beak, which 

 is somewhat efl^usively expanded at the tip. Outer li^D not mar- 

 gined, distantly toothed (about thirty), making a very acute angle 

 at its junction with the inner lip. Inner lip with a short, slight 

 ridge-like thickening at the posterior end, provided throughout 

 with long tooth-ridges (about twenty-five). 



Dimensions. — Length, 34; width, 19; height, 18. 



Locality. — Eocene blue-clay at Schnapper Point ; one example, 

 apparently not quite mature, as the posterior canal and the lips 

 are incompletely developed. 



5. CypPSea APChePi, Tenison- Woods. 



Reference. — Proc. Roy. Soc, Tasmania, tab. 1, tigs., 9-9a, 

 p. 22 (1876). 



Shell oval-subpyriform, moderately inflated. Shortly narrowed 

 and truncated at each end ; spire exsert ; surface smooth or 

 spirally lineate. 



Outer lip margined externally, thickly inflected, very slightly 

 produced behind, with about 20 rounded dental ridges ; inner lip 

 having a short elevated callosity confluent wdth the outer lip 

 intervening between which is a slight anal notch ; the inner lip 

 has about 15 subacute dental ridges. 



Dimensions. — The species varies a little in shape, particularly 

 as to the proportionate length. I give the measures of a short 

 and long example. (1) Length, 20; width, 13; greatest height, 

 11, at 9 mm. from the posterior end. (2) Length, 27; width, 

 15-5 ; height, 14. 



Locality. — Table Cape, Tasmania ! (R. M. Johnston). 



I cannot attach any of our Continental cowries to this species, 

 though it has a distant resemblance to C. j)yrulata and 

 C. Murraviana. Its inclusion in the published lists of River 

 Murray and Muddy Creek fossils is now withdrawn. 



6. Cyppsea Jonesiana, spec. nov. 

 This is comparable with C. Archeri ; from the short variety of 

 which it diflers by being less tumid and proportionately narrower, 

 from both varieties it diflers by its gentle front slope similar to 

 C. 'pyrulata. but it has not the produced posterior emargination 

 of that species.
