122 NEW SPECIES OF TERTIARY MOLLUSCA FROM VICTORIA 
on the body whorl, the interspaces somewhat wider. The lirae are smaller 
and more crowded on the periphery, but descending to the base and the canal 
they are stouter and more widely spaced. The whorls are crossed obliquely 
by delicate and close-set riblets which produce granules at the points of inter- 
section with the spirals. The riblets fade out at the base of the body whorl. 
Aperture narrow; sinus a slight flexure; outer lip thin (slightly damaged), 
a little incurved posteriorly; columella with two small, rounded plications 
about midway between the mouth and the posterior angle; canal short 
and well open. 
Dimensions.— Holotype. Length, 14 mm.; breadth, 6 mm.; length of 
aperture and canal, 8 mm. 
Observations. — This species bears some resemblance to the recent Mitrithara 
columnaria Hedley, but the fossil does not possess the strong cord and sulcus 
at the summit of the whorls such as found in the recent species. It also differs 
in possessing radial riblets which are absent in M. columnaria. In this respect 
the fossil approaches the recent Afitrithara proles Hedley, but in the latter 
case the radials are not so continuous, and they are curved rather than oblique. 
The spacing of the spiral lirae is also different. M. megale approximates 
closely to Mitromorpha daphnelloides T. Woods, but the former is a much 
larger species, and it does not possess the **broad, wide, groove-like space 
below the suture which is margined.” The outer lip of M. daphnelloides is 
lirate within, whereas in our species it is smooth.

Subgenus Enatimene Iredale. 
Trophon (Enatimene) makros, sp. nov. 
Plate XIV, Fig. 6. 
Shell narrowly fusiform ; whorls convex, a little shouldered in the posterior- 
third. Protoconch with one-and-a-half convex whorls, the apex flattened, 
the anterior half transversely costate. Adult whorls five and a half, the 
posterior ones crossed by axial costae producing nodulations on the periphery. 
On the penultimate and body whorl the axials are faint and narrow, about 
eleven on the penultimate, with the interspaces striate. The whorls are 
spirally lirate, the lirae rounded, and slightly nodulate at the intersection with 
the costae; about six principal lirae on the penultimate, with finer ones in 
the interspaces. The body whorl is similarly sculptured, about twelve main 
spirals, narrower than the shallow interspaces ; sutures well impressed, undu- 
lating. Aperture oval, acutely angulated at the posterior, and abruptly 
contracted at the anterior ; outer lip swollen a little distance from the margin 
externally, and lirate within, margin thin; columella excavated; inner lip 
continuous with the outer; canal of medium length, narrow, oblique, and 
reverted.
