UNRECORDED GENERA OF THE OLDER TERTIARY FAUNA. 175 
All our species have a globulose pullus, its tip immersed and 
slightly lateral; three of the following are near alliances to 
D. cataphracta, Brocchi. 
GENOTIA FONTINALIS, spec. nov., Pl. x., fig. 4. 
Fusiform, angulated at or a little behind the suture; the posterior 
area concave axially and ornamented with (about eight) slender 
lirze, tessellated by oblique threads, more or less granulose at the 
interstices ; the keel is granose-crenate, compounded of three or 
four equal-sized threads. Body-whorl in front of periphery with 
subgranose ribs (twenty) with interposed threads. Length 23, 
width 10, height of last whorl 17. Hocene:—Spring Creek near 
Geelong (common). 
The sutural position of the keel, its composite nature, and the 
tessellated ornament separate this species from G’. cataphriacta. 
GENOTIA DECOMPOSITA, spec. nov, Pl. x, fig. 8. 
This differs from G’. cataphracta by its shorter and stouter snout, 
by its shorter spire, more ventricose and bluntly angulated whorls, 
and in the absence of nodose crenatures on the periphery and at 
the posterior suture. The transverse ornament consists of slender 
arched threads which are not confluent in small groups at the 
suture. In its ornament it approaches more to G’. engonia, Watson, 
but that shell is slimmer and its whorls angulated. Length 28, 
width 12, length of aperture and canal 17:5. Localities—ocene: 
Gellibrand River, and Fyansford near Geelong. 
GENOTIA PRITCHARDI, spec. nov., Pl. x., fig. 9. 
Has a short stout snout and therein differs from G. fontinalis; 
it approximates to G'. cataphracta in the position of the keel which 
is however composed of three threads, Length 27, width 18. 
Locality—Miocene, Gippsland Lakes. 
Named in compliment to my young friend Mr. G. B. Pritchard, 
in whose company the species was s collected. 
GENOTIA ANGUSTIFRONS, spec nov., Pl. x., fig. 7. 
(Dolichotoma atractoides, Tate, M.S., non G. atractoides, Watson).
