on its dorsal side only, inclining to the left of the middle line 

 to near the apex. Aperture oblique, ovate-rotund. 



Dimensions. — Axial length, 5*5 ; major diameter of aperture, 

 1*25 millimetres. 



Localities. — Muddy Creek and Schnapper Point, Victoria. 



Compared with actual specimens of Cleodora subulata, Quoy 

 and G-aimard, this species is distinguished by its elliptical 

 aperture, by its proportionately greater breadth, and by its 

 abruptly tapering apex. 



Styliola bicarinata, spec. nov. Plate xx., fig. 9. 



Shell slender, conical, pointed, straight ; aperture trans- 

 versely ovate ; lateral margins strongly keeled. 



Dimensions. — Axial length, 625 ; major diameter of aperture, 

 2 millimetres. 



Locality. — Muddy Creek. 



Styliola annulata, spec. nov. Plate xx., fig. 1. 



Shell conical, straight, transversely annulated, smooth ; 

 aperture circular. 



Dimensions. — Axial length, 8 ; diameter of aperture, 2 milli- 

 metres. 



Localities. — Glauconitic clayey sands, Adelaide bore ; Tur- 

 ritella clays, Blanche Point, Aldiuga Bay. 



This species presents some resemblance to Creseis striata, 

 [Rang, but the shell is straight, not incurved apically, and the 

 annulations are on a larger scale. 



Vaginella eligmostoma, spec. nov. Plate xx., fig. 7. 



Elongate-ventricose, smooth, shining, apex acute ; the pos- 

 terior half is subcompressed, angulated on the sides, thence 

 narrowing to near the aperture, where the shell expands 

 laterally, though here the lateral compression is most distinct. 



The sculpture consists of very fine arched stria? descending 

 to the lateral angulations. 



The aperture is narrowly oval-oblong, with truncatedly 

 rounded ends ; each lip has a median curvature bounded on 

 each side by a broad insinuation. 



Dimensions. — Total length, 7 ; greatest transverse diameter, 

 1*75 millimetres. 



Locality. — Very abundant in the lower beds at Muddy 

 Creek. 



This species would appear to be distinct from V. depressa, 

 Basterot, of the Miocene Basin of Bordeaux and Dax, chiefly 

 by its sinuated aperture. Rang and Souleyet represent the 

 aperture of V. depressa as having simple margins meeting at 

 an angle.
