Victorian Fossils, Part XIX. 81 



Dimejisions. — Height, 11.25 mm. Width, 10 mm. 



Observations. — Lindstrom has figured a small Bellerox)hon (B. 

 pilula) from Gotland,^ which is even of smaller dimensions than the 

 Victorian, and which is of the same globular shape. Lindstroni's 

 species differs in the minute but clearly fenestrate ornament which 

 in ours is apparently evanescent on the growth-lines, and also in 

 the weaker sinus band. 



Occurrence. — Silurian (Yeringian). In limestone. Cave Hill, 

 Lilydale. Collected by the Rev. A. W. Cresswell, M.A. 



Genus Capinapopsis, J. Hall. 



Ca7'inaropsis victoriae, sp. nov. (Plate II., Figs. 13, 14). 



Description. — Shell patelloid, ovate, transversely elongate. Spire 

 prominent, narrowly rounded, depressed on the shoulders and 

 rapidly widening and expanding to the depressed subcircular body 

 cavity. Dorsum moderately convex, and depressed towards the 

 ventral and lateral margins. Surface relieved witli shallow sulcate 

 growth-folds and numerous radial folds or shallow riblets. Inner 

 surface shows a thick, broad, umbonal platform, beneath which 

 is a shallow groove corresponding to the carina on the external 

 surface. 



Dimeiisions. — Holotype. — Diameter from spire to ventral margin.. 

 18.25 mm. Extreme width, 22.75 mm. 



Paratype. — Diameter from spire to ventral margin, circ. 21 mm. 

 Extreme width, 24 mm. 



Observations. — The present species is nearly related to Garina- 

 rojisis ithagenia, Clark,^ a fossil of the Ithaca fauna, of Upper 

 Devonian age. The only differences existing between these forms 

 are the more salient spire, the depressed and more obliquely sloping 

 shoulders, and the more irregular growth-lines in the Victorian 

 species. 



Occurrence. — Silurian (Yeringian). In olive-brown mudstone. 

 Ruddock's Quarry, near Lilydale. Holotype coll. R. H. Annear. 

 Paratype presented by Mr. J. S. Green. 



Fam. Plkurotomariidae. 



Genus Pleurotomapia, Sowerby. 



Pleurotomaria maccoyi, sp. nov. (Plate II., Figs. 15-17). 



Description. — Shell trochoid, moderately high, the width and 

 height being nearly equal. Apical angle 80 deg. Whorls about six
