regards species or specimens, but by searching the debris round 
various wells I obtained the following :— 
Pecten polymorphoides, Zittel 
Pecten Gambierensis, 7’en.- Woods 
Amussium Zitteli, Hutton 
Waldheimia divaricata, 7'ate 
Terebratella Woodsii, 7'ate 
Terebratulina catinuliformis*, Z'ate 
Magasella Woodsiana, Z'ate 
Psammechinus Woodsii, Laube 
Hemiaster planedeclivis, Gregory 
Lovenia Forbesi, Zenison- Woods 
Scutellina patella, Z'ate. 
also numerous polyzoa, and the carapace of a crustacean. 
With the exception of the Pecten Gambierensis, which is per- 
haps only a variety of P. polymorphoides, all the above-named 
species occur in the River Murray cliffs, while only five, namely 
Pecten Gambierensis, Amussium Zittelli, Terebratulina catinuli- 
formis, Magasella Woodsiana, and Scutellina patella are to be 
found in any part of the Mount Gambier series, so we see here 
that while the character of the stone agrees with that of the 
Mount Gambier deposits, the fauna it contains has greater 
affinity with the beds of the Murray Cliffs. 
By the kindness of Mr. J. W. Jones, the Conservator of Water 
{to whom my sincerest thanks are due for supplying me with 
material from various bores, and also for many suggestions con- 
cerning this paper), I acquired some fossils obtained at a depth of 
200 feet from a well at Pinnaroo; and as the altitude of that 
place is only about 250 feet, these fossils were found not fer 
above sea level. However, I saw no samples of stone from any 
other part of the well; and so these may easily have been found 
near the base of the Eocene deposits there. The fossils were 
mainly in the form of casts, with the exception of several pallio- 
branchs, including Waldheimia Garibaldiana, W. grandis, and 
Magusella compta. Besides these there were recognisable, as far~ 
as casts ever can be determined, Cucullega Corioensis, Cassis 
exigua, @ Conus, and one or two Cypreas. This bed is clearly 
Murravian, both on lithological and on paleontological grounds, 
and so we have a connecting link between Bordertown on the 
south and the River Murray on the north, Pinnaroo being nearly 
midway between. In all probability bores put down north of 
Bordertown would reveal the polyzoal limestone of Mount 
* Nore.—This species is usually known as TJ. Davidsoni. As 
another species has this name the Australian shell has been re-named as 
above by Professor Tate.
