the occurrence of the cosmopolitan C. hlunienhiwhii at Yarra- 

 lumla. A remarkably fine example referred to this same genus 

 was figured by Mr. Jenkins from the Hume beds* He termed 

 it Calymene duplicata^ and gave 2J inches long as the size. In 

 1886, Mitchell recorded the occurrence of Calyviene from Bown- 

 ing.t Fn 1900, R. Etheridge described portions of two cephalons 

 from Cooper's Creek, Walhalla, of doubtful identity.; C. blu- 

 menbachii is stated by F. Chapman to occur in the Upper Yarra 

 beds, and also a species which he suggested to be C. tuberculuta 

 Salter. § Lastly, the same author described a Calpi'-eae as C. 

 aiKjustior from Ruddock's Quarry, near Lilydale, Victoria. |j

 (Plate xxiv., figs. 1-7 and 9; Plate xxvii., fig. 1). 



Complete form ovoid. 



Sp. Chars. —Cephalon sub-semielliptical, moderately inflated, 

 strongly granulated; average proportion of length to width approx- 

 imately 17 : 40; glabella large, bell-shaped, inflated moderately, 

 arched transversely, with a gentle slope anteriorly to the deep and 

 wide furrow separating it from the highly thickened labrum or 

 front margin, four pairs of glabella-furrows present, the anterior 

 pair only faintly visible on the upper surface, but deeply indenting 

 the sides and the axial furrows and thus forming a bar or ridge 

 between the front angles of the glabella and the fixed cheeks, 

 third and fourth pairs of lobes completely circumscribed, but cir- 

 cumscribing furrows shallow above; neck-furrow shallow medially 

 but deep behind the basal glabella-lobes, its extension across the 

 fixed cheek wide and shallow; neck-ring strongly arched, wide, 

 extensions across the free cheeks proximally very narrow but
