NEW SPECIES OF TERTIARY MOLLUSCA FROM 
VICTORIA. 
By the Bev. E. H. Chappie. 
Plate XIV. 
The type specimens of the Tertiary mollusca described 
below are in the National Museum, Melbourne. All were 
collected by the present author. 
I have to thank Mr. C. W. Brazenor for the excellent photo- 
graphs used in Plate XIV. 
Family FISSURELLIDAE 
Genus TUGALIA Gray (e.m.). 
Tugalia elata, sp. nov. 
Plate XIV, Fig. 8, 8a. 
Shell narrowly elongate, convex, back elevated, sides parallel. Protoconch 
somewhat worn, submarginal, less than one-fifth of length from posterior 
end ; from which a steep descent is made to the margin ; the anterior slope from 
the protoconch is very gradual for two-thirds of the length; radial ribs 
numerous, rather coarse, with finer ones in the interstices ; the radials are 
crossed by coarse concentric cords passing obliquely around the shell, some- 
what nodular at the points of intersection, and enclosing deep irregularly- 
shaped pits; sides parallel, regularly rounded behind, more narrowly so in 
front. Base slightly arched, margin weakly denticulated; anal sinus broad 
and shallow. Owing to the shell being somewhat worn, the sculptural 
features are not so pronounced as they otherwise would be. 
Dimensions. — Holotype. Length, 22 mm. ; breadth, 12 mm. ; height, 8 mm. 
Observations. — This fossil has distinctive features different from any other 
Australian described species, either recent or fossil. The nearest approach is 
the New Zealand fossil Tugali navicula described by Finlay, but our form 
differs from it in its greater altitude relatively to the size of the shell. Finlay’s 
species is “rather depressed,” whereas ours is elevated. 
Locality. — Cement Works, Railway Tunnel, Lower Mborabool River. 
Geological Horizon. — Barwonian. 
Holotype. — No. 14092. 
Family CYMATIIDAE 
Genus AUSTROTRITON Cossmann. 
Austrotriton halcomhensis, sp. nov. 
Plate XIV, Fig. 5. 
Shell ovate, body whorl ventricose, a short conical spire. Apex of proto- 
conch eroded in all examples of this species examined by the author, but
