74 RALPH TATE, 
In general appearance it resembles D. Testardi, Montrz.; but 
has somewhat tabulated whorls ; whilst the apertural characters 
are so distinctive as almost to warrant generic separation. 
Genus Lburnopsis. 
This generic name was proposed by me in Trans. Roy. Soc. 8. — 
Austr., 1888, p. 117, for a fossil having certain affinities with 
Lburna,; in addition to the type HL. awlacoéssa, two other speciés 
have since become known, all are Eocene, one of which is here 
described. 
EBURNOPSIS TESSELLATUS, sp. nov., Pl. xi, fig. 10. 
Shell like #. awalcoéssa, mihi, but very much smaller, base im- 
perforate, suture narrowly excavate, spire-whorls ornamented with 
linear spiral and axial sulci, which divide up the surface into 
rhombic flat nodulations. A well-marked revolving sulcus on the 
body-whorl terminates on the outer lip, a little in front of the 
middle, in a small tooth-like projection. Length 8:5, breadth 5. 
Locality—Eocene: Spring Creek, near Geelong (common). 
Genus Cyprea. 
Subgenus Cypredia. 
CYPREDIA CLATHRATA, Zate, Tr. Roy. Soc. 8. Austr., Vol. xm, 
tab. 9y mead, L892: 
The subgenera Cypredia and Cypreovula include the cowries 
with raised ornamentation, the former is distinguished from the 
latter by the absence of a posterior notch in the aperture. Five 
species have been described from the European Eocene; and the 
Australian congener is most like C. elegans, Defrance, but it is 
not so regularly clathrate in its ornamentation. 
Genus Genotia. 
This genus forms part of the Pleurotomide, and includes the 
oval-fusiform species having a slightly twisted columella, a short 
canal, and the sinus at the peripheral keel. The genus is best. 
represented in Eocene and Miocene strata. The Australian species 
of corresponding age, known to me, agree best with Dolichotoma, 
but I am not satisfied that it is clearly definable from Genoftia..
