Volnta ai'e worth mention. The first is a shell of the type of V. 

 lira/a, Johnston, but it differs from this species in many points, 

 amongst others the absence of costtB is conspicuous. 



The second shell is identical with a new species occurring at 

 Spring Creek, which, in the adult form is quite seven inches in 

 length with a characteristic long and slender spire terminated by 

 an embryo with a markedly exsert tip. 



The third, though an incomplete example, shows sufficient 

 characters to designate it a ne-w species with certain affinities to 

 an undescribed species from Muddy Creek, which is related to V. 

 Stephefisi, Johnston, of Table Cape. 



The fourth species belongs to the sub-genus Vohdoconus and 

 has its nearest ally in V. cojioidea, but it is readily distinguishable 

 from this species as the spire is much shorter and the whorls 

 more tumid. 



Cyprcea Mulderi, Tate, is a shell we wei'e not at all soriy to 

 see turn up, as the only two examples previously found were 

 obtained in sinking a deep well in Belmont. The type specimen 

 is in the Adelaide University Museum and the second one is the 

 property of Mr. Mulder of Geelong. Two additional examples 

 were obtained. 



A small and very pretty undescribed species of Nautilus 

 turned up, which is apparently identical with the one occurring at 

 the Gellibrand River and Muddy Creek. 



The amount of disturbance in eocene strata as shown here is 

 apparently unparalleled in Southern Australia and is evidently 

 merely local. The polyzoal rock in M'Cann's quarry at Waurn 

 Ponds dips S. 10° E. at 3" or 4°. The sandy limestones at Belmont, 

 on the river bank just above Barwon bridge, dip E. 40° S. 10°. 

 While between these two localities in the bed of the Wauin 

 Ponds Creek, about 300 yards below where the Geelong to Colac 

 road crosses it, the dip is JST. 25° W. 7°. The Muddy Creek beds 

 are stated by Mr. J. Dennant* to be horizontal, while Professt)r 

 Tate, speaking generally of the Older Tertiaries of Southern 

 Australia, saysf that " for the most part secular elevation of the 

 Older Tertiary sea bed has been of small amount and uniform."
