 Quercus Saffordii Lx. Plate v, figs. 1-;S. 



The description of the species is given in Geol. Tenn n 407 nl K

It is comparable, indeed much like the small leaves referred to 

 Quercus Jurcinervis Rossin. by Eugelhardt (EL v. Leitm p 402 ro<>l 

 PI. xxv [x], figs. 10-19), which differs from the American form in haling 

 the secondaries more regular, at equal distances, and not separated bv 

 tertianes, which do not correspond to teeth of the borders but are 

 shorter, camptodrome, or ending in the areolation. From the de 

 scription of Eugelhardt and the figures of Quercus furciuerr is in Ett.

Specimens from Van Horn's ranch, John Day Valley, Oregon, col- 

 lected by Capt. Charles Bendire, U. S. Army. The age of these beds 

 is Miocene, probably latest Miocene. 

 Magnolia lanceolata Lx. 



One specimen; Museum number, 2514. 

 Magnolia Inglefieldi Heer. PI. Art. I, p. 120, PI. xvni, figs. 1-3. 



I refer the specimen to the species with some° doubt, as Heer de- 

 scribes the leases as having a thick medial nerve, being coriaceous and 

 the surface polished. In these leaves, which are, however, impressions 

 of the lower surface, the medial nerve is comparatively thin, though 

 thick proportionally, to the secondaries; the texture is not coriaceous 

 and the surface is not polished. The nervation is, however, of the same 

 type; the secondaries distant; the areas broad, the nervilles or terti- 

 anes distinct, and the areolation very small, quadrangular, pitted by 

 points as in fig, 3« of Heer; it must be remarked also that fig. 1 of 

 Heer has not the medial nerve broader than of the leaf in specimen. 



One specimen ; Museum number, 2513, 

 Liquidambar protensum Uug, Plate viii, fig. 3, 



The ^leaf has the characters of the species as represented in Heer, Fl, 

 Tert. Helv., p. 8, PI. in, fig. U. It is, however, deformed bv maceration, 

 the medial nerve of the middle lobe being displaced from its point of
