Leiostraca acutispira. PI. 1, fig. 2. 



Testa parva, subulata, medio pa/rum ventricosa, polita, tenui ; anfr. 

 11, hand lat is, omminolcevilus, sutura vix visibili ; apertura pyriformi ', 

 hibro antiee producto ; labio parvo, angusto, rotundato. Long. 8^-, 

 lat. 2. 



Shell small, subulate, slightly ventricose in the middle, polished, 

 thin ; whorls 1 1 , not wide, altogether smooth, suture scarcely 

 visible, aperture pyrif orm, labrum produced anteriorly, lip small, 

 narrow, rounded. 



The differences between this shell and L australis, our only 

 Australian species, are, first that the fossil is smaller, opaque, 

 much more acute in the spire, with many more whorls in propor- 

 tion ; there is a peculiarity in L. australis from which this fossil 

 completely differs, the top of the spire is obtusely rounded and 

 on the summit the nucleus is placed like a little granule. 



CONUS PULLULASCENS. Pl.l, fig. 3-4. 



The two cones figured on this plate I only name provisionally. 

 They are the same species, but fig 4 is very much worn. The 

 specimens seen by me are all extremely small with a very large 

 conspicuous pullus, the upper angle of the whorls is distinctly 

 and elegantly ribbed, and the whole shell is deeply and distantly 

 spirally grooved. Larger and more numerous specimens may 

 enable me to give better details, and more information as to the 

 relations of the species. 



Leda lucida. PI. 1, fig. 5 and 5 a. 



Testa parva, tumida, solida, polita, cequilaterali quasi, ovata, con- 

 eentriee regular iter costata, cost is rotundatis, cequalibus; latere post ico 

 vix producto, subacute angulato, area postangulari vix sulcata ; latere 

 antico brevi, obtuse rotundato, umbonibus subacutis. Long. 3^-, lat. 

 *)o", arc. — . 



Shell small, tumid, solid, polished, equilateral, almost ovate, 

 regularly concentrically ribbed, ribs rounded equal, posterior side 

 scarcely produced subacutely angular, posterior angle scarcely 

 sulcate, anterior side short, obtusely rounded, umbone subacute.
