UNRECORDED GENERA OF THE OLDER TERTIARY FAUNA. 173 
Cantharus, and Pisania purpuroides (Johnston), Tate, may be 
replaced in Aicinula. These transferences eliminate the genus. 
Pisania from our list. 
Genus Harpa. 
HarpPA PACHYCHEILA, spec. nov., Pl. xi., fig. 5. 
This species belongs to the Section Kocithara, Fischer, to the 
type of which H. mutica, Lamk., of the Parisian Eocene, it bears 
some resemblance, differing by its angulated whorls and the 
absence of the delicate clathrate ornament between the costae. 
It resembles also H. abbreviata, mihi, but has angulated whorls, 
acute not lamellate costae, intercostal spaces distantly cross-barred,. 
pullus small, and outer lip excessively thickened (which ascends. 
to near the keel of the penultimate whorl. Length 27, breadth 
17 mm. Locality : Eocene, Spring Creek (common). 
Genus Pyrula. 
This genus is represented in the Eocene beds of Table Cape, 
Tasmania, by a large species, known to me by two examples in the 
collection of Mr. T. Atkinson ; it is undescribed. 
Genus Dolium. 
DoLIuM BIORNATUM, spec. nov., Pl. x., fig. 5. 
Shell thin, elliptic-oval ; spire elevated; imperforate ; whorls. 
Six, ventricose, slightly flattened posteriorly, suture linear. Penul- 
timate and body-whorl with narrow flatly rounded encircling ribs 
(six or seven on penultimate whorl), anda riblet or thread usually 
interposed, crossed by rather distant growth-lines. Posterior 
whorls ornamented with slender spiral ribs, alternating with threads, 
tessellated by raised strie, which produce crenatures on the 
principal lirae. Outer lip narrowly expanded and slightly reflected, 
crenate-dentate. Columella simple, long and straight; beak short, 
narrow and slightly oblique and upturned. Length, 48 ; width, 
45; length of aperture, 37. Localities—Eocene: Fyansford 
(Mulder), Muddy Oreek (Pritchard). |
