ENUMEEATIOX AXD DESCRIPTION OF FOSSIL PLANTS 

 FEOil THE WESTERN TERTIARY FORMATIONS. 



South Parle, near Castelld's Range. 



A yellowish, lammated, soft sbale, breaking easily and splitting in 

 tbin layers. Remains of plants well preserved and distinct, with 

 remains of insects and feathers. Specimens collected and communicated 

 by ]VIr. S. A. Allen. 



Ophiog-lgssuii Alleni, sp. mv. 



Leaf, elliptical, narrowed by a curve to the acute base 5 shorter and 

 broader than in 0. vulgatum, L., of our time, with the same areolation- 



The leaf is about 3 cent, long, (point broken,) a little more than 

 2 cent, broad, marked in the middle by the remnant of a fruiting 

 pedicel. No fossil species of this genus has been as yet published, but 

 a smaU one, 0. ceocemim, Mass., from the Tertiary of Verona, Italy. 



Thtjites calliteesta, Ung., cMor., p, 22, PI. vi, Fig. 2. 



' Though the fragments are small, they are very distinct, and there is 

 no appreciable difference from the description and figjires of this 

 species. The same specimen bears a fragment of Salix like S. lingu- 

 lata, Gopp. 



Pla:xera longifolia, sp. nov. 



Leaves oblong, lanceolate, obtusely pointed, wedge-shaped at the base 

 to a petiole; borders simply dentate; secondary veins thick, simple, 

 crasi)edodrome. 



It differs from Planera Ungeri, Ett., and its varieties, by longer, pro- 

 portionally narrower leaves; by more oblique, straight, always simple, 

 secondary veins, which are thicker and more distant; by more obtuse 

 and larger teeth; some of the leaves are unequal at base and curved 

 on one side. Average length, 4 cent., 1^ cent. wide. The distinct 

 areolation is that of the species as marked in Heer, Fl. Fert. Helv., PI.
