Palceontology of Older Tertiary of Victoria. 105 



28 imn. (slightly imperfect) ; length of aperture, 10 mm. ; 

 breadth of aperture, 7 mm. ; length of canal, about 10 mm. 



Locality. — Eocene clays of Mornington. Collected by Mr. W. 

 Wallace. 



Observations. — This very pretty and distinct species was 

 collected from the Mornington clays by a past geology student 

 of mine, Mr. W. Wallace, of the Department of Mines, Mel- 

 bourne, and I have therefore much pleasure in associating his 

 name with this shell. Its characters are so very well marked 

 and distinctive, that 1 do not think it can be easily confused 

 with any of our previously described fossil species. 



Voluta fulgetpoides, sp. nov. PI. VII., Fig. 4. 



Shell robust, fusiformly oval ; spire about one-third the length 

 of the shell, or a little less, terminating in a smooth convex 

 mammiliate embryo of one and a half to two obliquely enrolled 

 whorls of moderate size, whose apex is laterally immersed. In 

 addition to the embryonic whorls, there are three or four, 

 generally four, convex whorls, the body-whorl of some specimens 

 being somewhat more tumid and regularly rounded from the 

 suture than others. Suture distinct, somewhat impressed ; the 

 whorls are ornamented with very tine close spiral strise, tending 

 to become obsolete on the body-whorl in most specimens, 

 occasionally several fairly strong spiral threads show on the 

 body-whorl; the lines of growth are well marked and occasion- 

 ally through their irregularities give rise to slight undulations. 

 This species was to all appearances colour-marked, judging by 

 certain irregular brownish patches, but these are not sufficiently 

 detined in the present specimens to accurately indicate their 

 nature. 



Aperture elongate oval, about two-thirds the length of the 

 shell. Inner lip strongly enamelled with a much thickened pad 

 at the posterior end in the adult ; columella furnished with three 

 to four strong oblique plaits ; outer lip much thickened, this 

 character being most marked medially, becoming thinner 

 anteriorly and posteriorly, and marginally reflected, ascending 

 the penultimate whorl for about one-third its height, and 

 distinctly continuous with and merging into the enamelled inner
