described fossil. According to this difference these fruits cannot belong to 
the same species, though both arc comparable only to the fruit-stones of 
Elceocarpus sphcericus, Gaertn., which likewise is divided into equal pieces 
corresponding to its live seed-receptacles. 
The leaf, PI. XIV, fig. 5, from Vegetable Creek, agrees so entirely with 
leaves of Elceocarpus, especially with those of E. Cummingii, that scarcely any 
doubt need arise on the question as to whether it should be united with the 
above fruit from Elsmore or not. Elceocarpus Cummingii, H.B.V. (Ettings- 
liausen, Blattskeletc der l)icotyledonen, PI. LI, Gg. 5), which is to be con- 
sidered most analogous to our fossil species, strikingly approaches it in texture, 
form, borders, and nervation of the leaf, the latter being represented in Pig. 
5a, enlarged. 
Amongst the species of the European Tertiary Plora, the following may 
be considered as the nearest related species : — Elceocarpus AlbrccMi, Heer, 
the formation of the fruit, and E. curopecus , Ett., from the Possil Plora of 
Bilin, as regards the leaf. 
I named this species iu honor of Baron Perdinand von Mueller, of 
Melbourne. 
Locality and Horizon. — With the preceding species. And Ncwstead, 
near Elsmore ; in concretionary ironstone (earthy limonite), associated with 
basalt.

in Fig 2a, magnified. A species very closely allied to that just named, which
