GEOLOGICAL SURVEY OF THE TEERITOEIES. 7 



European specimens, presenting, however, some marked differences. The 

 leaves are not long-acutely pointed, but obtusely so ; though the primary 

 and secondary nervation are alike, the ultimate divisions of the veins 

 approach nearer to the borders, and sometimes the teeth of the borders 

 appear rather pointed than round. As this species is very variable, these 

 differences are not marked enough to authorize a separation. The gen- 

 eral form of these leaves of ours rather resembles the variety in Heer's 

 Fl. Ter. Helv., PI. Ixxxv, Figs. 1 and 2. 



Ficus Ungeri, sp. nov. A splendid leaf, of which unluckily the point 

 and lower part are destroyed. It is broadly lanceolate in outline, the 

 borders nearly parallel in the middle of the leaf, apparently rounded to 

 the petiole and also curving upward somewhat abruptlj?^ to a point. The 

 part of the leaf as it is preserved is 8 inches long, 4 inches wide, with 

 entire, slightly undulate borders, not coriaceous; medial nerve rather 

 thick; secondary veins at a broad angle of divergence, (70° to 80°,) and 

 tertiary nervation distinct, of the same type as that of F. Americana, 

 The surface of the leaf is runcinate, as in F. populina and F. tilkcfoUa; 

 but the form of the leaf and the open, nearly horizontal secondary veins 

 separate this species from any other known as yet in a fossil state. The 

 leaf is larger than that of F. Hercules, Ett., or that of F. Ruminiana, 

 Heer; comparable only, for the form and size, to the living F. ferruginea, 

 which has also the secondary veins in an open angle. In the fossil 

 species, these veins curve less abruptly and approach nearer to the bor- 

 ders in their ultimate curve. 



OiNNAMOMUM SoHBUZERi, Hccr. I refer to this species two leaves 

 of Cinnamomum, one of which is contracted above the base, as in some 

 forms of G. BucM, Heer; the other narrower, like a variety of C. laneeo- 

 latiim, Heer. Both specimens are incomplete and have the nervation of 

 €. Scheuzeri, as represented in many specimens from other localities of 

 our Tertiary. 



Eucalyptus Amerioanus, sp. nov. Eepresented by good speci- 

 mens. Leaves narrowly laii?ceolate, 5 to 6 inches long, ^ to f of an inch 

 wide, entire, gradually tapering upward to a long point, tapering also, 

 but less gradually, to the base of the flat, broad, medial nerve, which is 

 merely enlarged at the point of attachment ; secondary veins oblique, 

 (divergence about 30°,) numerous, ascending nearly straight to near the 

 l3orders, where they join a marginal vein, which follow the borders from 

 the base to the point of the leaves, being scarcely bent to the point of 

 union of the secondary veins, and thus forming a narrow, equal margin, 

 marked by horizontal, thin, simple, parallel, and close veinlets. This 

 fine species is distantly related to F. OGmnica, Heer, Fl. Ter. Helv., and 

 may be still more so to F. rJiododendrifolia, of Massalonga, which has, 

 like ours, the true nervation of Eucalyptus., but is differing at least by 

 its leathery texture,, which is no coriaceous in ours. I know this Italian 

 species merely from description, and cannot, therefore, indicate points 

 of analogy. 



Ampelopsis tertiaria, sp. nov. A digitate leaf, with five nar- 

 rowly ovate, lanceolate-pointed leaflets, tapering downward to a short, 

 slightly winged petiole, sharply serrate on the borders; medial nerve 

 flat and broad; secondary veins in acute angle, curving along the bor- 

 ders, branching upward and anastomosing downward with branches 

 of the ui^per veinlets. The nervation is similar to that of our living A. 

 quinquefoUa, Michx., the branches of the secondary veins entering the 

 teeth, while the primary divisions follow the borders. It differs from it, 

 however, by smaller and narrower leaves, short, winged petiole, &c.
