4. Conus pulluleseens, T. WoocU. 



Reference. — Proc. Linnetin Soc, New South Wales, vol. IV., 

 p. 3/ pi. i., fig. 4 (noil. 3), 1880. 



The author of the species-name included two different species 

 under it, but both examples represent very young, almost un- 

 recognisable, shells ; however in respect of one (fig. 4), I have been 

 able to trace it up to a shell of moderate size (herewith figured), 

 to which the specific designation is very applicable. 



The species is conspicuous by its large turbinated pullus of 

 three smooth tumid whorls. 



The spire is either flat or very shortly elevated, its whorls nar- 

 row, separated by a linear suture ; ornamented with four or five 

 spiral threads and rather slender, close, arched growth-lines. 



The body-whorl is sharply angled, and is ornamented with flat 

 spiral threads, becoming more or less obsolete with age (except 

 at the front). 



Dimensions. — Length, 32 ; greatest width, 15 ; length of 

 aperture, 27 ; diameter of pullus, 3-5. 



Localities. — Eocene beds at Muddy Creek, Schnapper Point, 

 and River Murray Cliffs. 



5. Conus ligatUS, spec. nov. 



Shell biconic ; spire of variable height, but usually moderately 

 low, consisting of about seven gradated whorls, ending in a small 

 naticiform pullus of one and a-half smooth whorls ; body-whorl 

 more or less subpyriform. 



Spire-whorls with an obtuse thick shoulder, the two slopes in- 

 clined approximately at a right angle and of about equal width ; 

 the posterior area is usually flat or slightly concave, rarely Avith 

 a siight upward inclination ; it is ornamented with four or five 

 spiral threads, separated by narrower furrows, and rather close- 

 set stria? of grow^th, conformable with the anal insinuation of the 

 outer lip ; the anterior area is provided with one or two threadlets 

 margining the rib-like keel. 



Body-whorl varying from pyriform to elongate-ovate, the peri- 

 pheral keel defined anteriorly by a linear constriction, posterior to 

 which there are one or two threads on the peripheral band. The 

 surface is sculptured at the posterior part with incised linear 

 lines, which towards the front become wider, and are finally re- 

 placed by ribs narrower than the shallow interspaces ; the whole 

 is crossed by growth-lines, which produce punctations in the 

 linear sulci, and a fenestrated ornament anteriorly. The strength 

 of the encircling lines is variable, and may be obsolete in the pos- 

 terior half of the body-whorl. 



The aperture is narrow, with a short anal sinus corresponding
