Dimensions. — Total length, 58 ; greatest diameter, 30 ; length 

 of aperture, 56 ; length and breadth of puUus, 2. 



Localities. — Rather common in the lower beds at Muddy Creek, 

 and in the blue clays at Schnapper Point. Calciferous sandstones 

 of the River Murray Cliifs near Morgan. 



2. Conus ptyehodermis, -^pec. nov. 



Shell narrow, conoidal, a little more than twice as long as 

 wide ; spire very low, ending in a small obtuse pullus of two 

 smooth whorls. 



Spire consisting of four and a-half narrow flat whorls separated 

 by a narrow channelled suture ; ornamented spirally by a medial, 

 more or less prominent, thread, with or without a few thread^ ets, 

 crossed by arched prominent growth-ridges and by coincident 

 stride. 



Body-whorl obtusely angled at the periphery, regularly tapering 

 to the front ; ornamented by inconspicuous spiral threads, which 

 are wrinkled by the intercrossing of growth-folds, between which 

 the surface is slightly contused. 



Dimensions. — Length, 30; greatest width, 13; height of aper- 

 ture, 28. 



Locality, — Eocene beds at Muddy Creek. 



3. Conus eoraplieatus, sj)ec. nov. 



Shell varying from broadish- to narrow-conical, about twice as 

 long as wide, spire very short, ending in a small obtuse pullus of 

 two smooth whorls, the tip centrally immersed. 



Spire-whorls four, narrow, the periphery slightly exsert, behind 

 which they are slightly concave ; ornamented by three or four 

 broad depressed lira3, tessellated by regular, deeply arched, growth- 

 ridges. 



Body-whorl sharply angled and slightly elevated at the peri- 

 phery, regularly tapering to the front ; sculptured by somewhat 

 regularly-disposed linear sulci; separated by broad depressed 

 ridges of which the first and fourth are usually broader, more 

 elevated, and covered with flat granulations which range more or 

 less in lines coincident with the striae of growth. 



Growth lines prominent, moderately ecurved, which produce 

 slight crenatures in the spiral furrows. Outer lip slightly ecurved 

 medially, deeply arcuately notched behind the peripheral angu- 

 lation. 



Dimensions. — Length, 18-5 ; greatest width, 10 ; length of 

 aperture, 16*5 ; of another specimen, they are respectively 21, 

 10, 18. 



Localities. — Eocene beds at Muddy Creek and Schnapper 

 Point.
