ORTMANN I TERTIARY INVERTEBRATES.

I have further tried to compare our Patagonian fossils with those of the 
Tertiary beds of Tasmania and southern Australia , and am able to give 
the following list of relations : 
Melicerita triforis M. angustiloba , S. Australia (? Miocene). 
Reticulipora patagonica R. transennata , S. Australia (? Eocene). 
Rhynchonella squamosa same species in Tasmania (? Miocene). 
Nucala patagonica N. tumidct , Australia, Tasmania (? Eocene). 
Leda oxyrhyncha and errazurizi . similar species in Australia. 
Limopsis insolita same species, S. Australia (? Eocene). 
Area patagonica A. pseudonavicularis , Australia (? Eocene). 
Ostrea ingens 0 . sturtiana, River Murray Cliffs (? Miocene). 
Gryphcea cf. tarda G. tarda, S. Australia (? Eocene). 
Pecten prcenuncius P. palmipes , Australia (? Miocene). 
Venus meridionalis V imdtitceniata and hormophora, Australia, Tasmania (? Eocene). 
Dosinia meridionalis D. denselineata, Tasmania, Victoria (? Miocene). 
Psammobia patagonica P. hamiltonensis , Victoria, Tasmania (? Eocene). 
Dentalium sulcosum D. mantelli , Australia, Tasmania (? Eocene). 
Turritella ambidacrum T. aiding oe, S. Australia (? Eocene). 
Voluta triplicata V sarissa and tateana, Australia (? Miocene, Eocene). 
Voluta ameghinoi V atkinsoni, Tasmania. 
No attempt has been made to correct or to control the age given for 
these Australian species. This list is very defective, since it was impos- 
sible for me to make a closer comparison, especially because the figures 
of Australian species given by Tate (1886-1893) are in most cases very 
poor. Nevertheless the fact is apparent that a few identical species are 
found, which are in part also recorded from New Zealand, and that a 
larger number of species show close affinities with Patagonian forms. 
The latter number will undoubtedly be increased considerably, after a 
careful examination of the Australian fossils has been made. For the 
present, it is sufficient to call attention to the fact that not only in New 
Zealand, but also in Australia and Tasmania, Tertiary deposits are found, 
which yield a fauna that shows unmistakable affinity to the Patagonian 
fauna. 1 
According to Harris (1897), whose Australasian Tertiary Mollusca were not consulted until 
the above was written, I can add the following striking cases : 
Liotia scotti L. roblini Johnst. (Harris, p. 284, pi. 8, f. 4) “Eocene,” Muddy 
Creek. 
Fissurella eurytreta Fissurellidea malleata Tate (ibid., p. 287, pi. 8, f. 5) “Eocene,” 
Muddy Creek.
