greater number; one may finally add, A. Jurgenseni , Ileer, from the beds of 
TJnartok, as a species of the Arctic Tertiary Flora analogous to our own. 
Locality and Horizon. — Old Ruse Valley Lead, with the preceding 
species. 
Aralia Oxleyi, sp. nov. 
Plate Xlir, Fig. 25. 
Sp. Clwr. — A. foliis coriaceis, palmato-lobatis, lobis insequalibus, 
oblongis, basi contracta integerrimis, sub angulis acutis inter se divergentibus ; 
nervatione actinodroma ; nervis primariis laborum yalidis ; nervis secundariis 
tenuissimis, sub angulis 50-60° insertis. 
Ohs. — The fossil, Fig. 25, belongs likewise to an Aralia. Very pro- 
bably this was five-lobed ; accordingly one should suppose that our fossil 
exhibits the middle lobe and the two lateral lobes of one and the same side. 
The lobes are not equal to one another ; the exterior lateral lobe is at least 
smaller. All arc somewhat narrowed at their base, and are entire there. The 
sinus has narrow angles of divergence, 20° to 30°. The strong primary nerves 
send out very tliin secondary ones, being preserved only on a part of the first 
lateral lobe. The network is obsolete. 
Relating to the breadth of the lobes, this species reminds us of Aralia 
grccnlandica, Ileer, and taking the number of lobes into consideration one 
might find the A. primigenia, De la Harpe, to be an analogous species. But 
the former species possesses thrcc-lobed leaves, and the latter much narrower 
lobes. 
Locality and Horizon. — Old Rose Valley Lead, with the preceding 
species. 
Aralia elsmoreana, sp. nov. 
Sp. Char. — A. foliis palmato-lobatis (?) ; nervatione actinodroma; nervis 
primariis validis, subangulis 39-35° inter se divergentibus ; nervis secundariis 
subangulis 55-65° orientibus, curvatis ramosis ; nervis tertiariis e primariis 
angulo subrecto, e secundariis angulis acutis variis egredientibus inter se 
c mjunctis rete macrosynammatum formantibus. 
Ohs . — A fragment of a large leaf being most probably palmatilobed, 
and plainly exhibiting the nervation of an Aralia, has been found at the 
abovenamed locality. It shows three almost equally strong primary nerves,
