has the whorls flatter behind and is (usually ?) without varices ; 

 but ,S. MaricH has nearer allies in <S'. Zeleboin, Frauenfeld, and 

 aS'. lyrata, Zittel. From the former it is easily separable by its 

 fewer costte, distinct varices and more elevated and thinner liraB ; 

 from the latter by its more numerous and lamellated costte. 



14. Sealaria (Cirsotrema) pleiophylla, spec. nov. 



Shell like Circuhscala foliosa, but with a distinct basal keel. 

 Its numerous frilled lamella? separate it from Cirsotrema Marice. 



There are two rounded apical whorls, the first of which is 

 somewhat depressed, and about ten ordinary whorls ; there are 

 20 to 25 costa3 to a whorl. 



Dimensions. — Length, 20 ; width, 5-5. 



Localities. — Eocene. Adelaide bore ; Corio Bay and Spring 

 Creek, near Geelong. 



15. Sealaria (Eglisia) triplieata, spec. nov. 



Shell moderately stout, turrited, about four times as long as 

 wdde, imperforate ; whorls about 15, of which the two nuclear 

 ones are roundly angled and obscurely Urate, apex acute : the 

 earlier spire- whorls medially angulate, the convexity becoming 

 more and more tricarinate with the slow revolution of the spire, 

 more contracted in front than behind. Suture distinct. 



The spiral ornament consists of three prominent elevated 

 rounded lirse, which are equidistant and approximate, the middle 

 one is the stouter and is slightly in front of the middle line of 

 the whorl ; a small thread is interposed between the posterior 

 carination and the suture. 



The transverse or axial ornament consists of thin slightly 

 elevated lamelliform costse, equal and equidistant, about 25 to a 

 whorl, are continuous from whorl to whorl and become wider 

 apart with the revolution of the spire ; the lamell?e are oblique, 

 but curved forward at and decurrent with the posterior suture. 

 There are no varices. 



Body-whorl with four strong lira?, the anterior one in an align- 

 ment with the suture (though there concealed) forms a basal 

 keel ; base flatly convex, with about 10 concentric threads, crossed 

 by radiating threads continuous with the lamelliform cost^e. 



Aperture squarely rounded, peristome incomplete ; outer lip 

 thin ; columella reflected and slightly efFusedly dilated at the 

 front. 



Dimensions. — Length, 28 ; width, 7 ; height and width of 

 aperture, 5. 



Localities. — Not uncommon in the Miocene-strata at Muddy 

 Creek ; and at Red Bluff, Gippsland Lakes. Also Older Pliocene ; 

 Croy don-bore, near Adelaide. 



I have attached this species to Eglisia, because of the close
