form, the more distant, more prominent, and very unequal secondary veins, and 
the most acute-angled tertiary veins. It must therefore be incorporated with 
a particular species, corresponding very well to still existing species of 
Bombax , with large and broad leaflets (compare Ettingshausen loc. cit., PI. 
II, tig. 2; PI. A , tig. 7). Prom this the Bomb ax oblongifolium, Ett., from 
the Fossil Flora of Filin, is distinguished only by more approximate loop- 
forming secondary veins, and shorter tertiary veins. 
1 he species is named after Sir Thomas Mitchell, who lias done much 
for the promotion of Australian Geography.

Sapindus tasmanicus, sp. non. 
Plate VI, Fig. 8. 
Sp. Char. — S. foliolis coriaceis insequilateris, ovato-lanceolatis, acu- 
minatis, integerrimis ; nervatione camptodroma ; nervo primario firmo 
prominente ; nervis secundariis distinctis, subangulis 55-65° orientibus, 
arcuatis simplicibus vel furcatis marginem adscendentibus, infimis angulis 
acutioribus egredientibus ; nervis tertiariis baud conspicuis. 
Obs . — A leaflet, whose asymmetric outline reminds one of the leaflets 
of both Sapindacem and Allan Urns. Even the venation would not, as respects 
the small number of secondary veins, be incompatible with the latter genus. 
But there are also present basal acute-angled secondary veins, which 
are not found in Ailanthus. Such arc, however, found in Sapindus, for 
example, A esculentus, St. Hil. In S. falcifolius, A. Braun, the lowest 
secondary veins also issue, at least on one side, at more acute angles than the 
others. The only character inconsistent with Sapindus, in the present 
instance, is the small number of secondary veins. In this respect the fossil 
would agree better with other Sapindacese, e. <j., Schmidelia and Serjania ; 
but taking into consideration the form and the other characters of the 
venation, it does not at all correspond to those genera, but best to Sapindus. 
In the North American Tertiary Flora we find a species, the S. caudatus , 
Lesq., whose leaflets resemble the form and acuminate apex of our fossil; also
