Dimensions. — Length and breadth of shell, 28 and 22, of aper- 

 ture, 16 and 8. 



Locality. — Bairnsdale, Gippsland ( W. H. Gregson I ). 



Pelicaria coronata, Tate. Plate x., figs. 6 and 13. 



Reference. — Southern Science Record, January, 1885, p. 2. 



Shell ovate, spire acute, whorls eight, angled, suture chanelled. 

 Surface ornamented with transverse strise and spiral ridges, and 

 a row of small nodulations on the angle of the whorl. Last whorl 

 sub-quadrate, slightly depressed in the middle line ; angle with- 

 out nodulations and separated from the suture by a broad and 

 deep groove. Callus-enamel spreading over the whole of the 

 body-whorl and the anterior-half of the penultimate whorl. 



Dimensions. — Length and breadth of shell, 45 and 32 ; of 

 aperture 2-3 and 14. 



Localities. ^U^^ev beds at Muddy Creek (J. Dennant); 

 Gippsland beds at Cunningham e. Jemmy's Point, and Reeve's 

 River (W. H. Gregson I ) ; well-sinking, Murrray Desert (R. T.). 



Of the two fossil species, P. coronata makes the nearest ap- 

 proach to P. scutulata, but it has a shorter spire, nodulate rather 

 than crenate on the keel, whilst the canaliculate suture of the 

 body- whorl is very distinctive.
