AUSTRALASIAN TERTIARY BRACHIOPODA 
33 
Description. Outline subquadrate, greatest 
width at or slightly posterior to mid-length; dor¬ 
sal valve with flattened umbo; anterior commis¬ 
sure deeply and narrowly sulcate. Beak suberect; 
cardinal margin straight; symphytium wide, flat 
to gently concave. Hinge platform wedge- 
shaped, almost square with indented posterior 
margin; surface relief low; posterior surface of 
cardinal process large, lateral surfaces lining 
posteriorly projecting socket ridges. Medium 
septum thick, low, terminating mid-length of 
valve. Loop with thin lateral connecting bands. 
Hinge teeth triangular in outline. Beak interior 
and lateral walls heavily thickened, leaving 
round tunnel for pedicle. 
Comments. Sovverby (in Strezlecki 1845) de¬ 
scribed Terebratula compta on the basis of speci¬ 
mens collected from “an elevated beach at Port 
Fairy” on the Cape Otway coast, Victoria. Tate 
(1880) noted that “Strezlecki mistook our Older 
Tertiary deposits for Post Tertiary beaches”. 
Port Fairy (if considered as synonymous with 
Point Fairy) contains no Tertiary outcrops 
although they occur inland in this general area. 
In 1865, Tenison-Woods referred specimens 
collected at Mount Gambier and Portland to 
T.compta and his figures agree with those of 
Sowerby. The Natural History Museum, Lon¬ 
don, where some of Sowerby’s material is de¬ 
posited, has no record of T. compta. The speci¬ 
mens described and figured herein were col¬ 
lected from the Mount Gambier Limestone 
(Janjukian, Upper Oligocene) at Portland, Vic¬ 
toria. Since no problem exists in the identifi¬ 
cation of Sowerby’s species, and in accordance 
with Article 75 (b)(ii) of the International Code 
of Zoological Nomenclature, it is not considered 
necessary to designate a neotype.

Description. Outline elongate-ovate with great¬ 
est width at mid-length. Beak straight, 
symphytium slightly concave, cardinal margin 
curved. Hinge platform outline trapezoidal; pos¬ 
terior ends of socket ridges blunt, projecting 
slightly beyond posterior margin of valve; boun¬ 
daries of components of platform not identifi¬ 
able. Median septum extending slightly beyond 
mid-length of valve, high anteriorly. Loop with 
ascending and descending branches separate, at¬ 
tachments to septum wide. Hinge teeth triangu¬ 
lar in outline. Lateral walls and beak interior 
heavily thickened, leaving round tunnel for 
pedicle. 
Comments. Dr G. Kendrick (pers. comm.), 
Western Australian Museum, considers the age 
of the bores to be Pliocene to Early Pleisto¬ 
cene.
