30 DESCRIPTION OF SPECIES. 



distinct, half a millimeter distant, with an indistinct veinlet in the narrow 

 intervals. 



The form of this leaf is peculiar, without relation to any of this genus.

Figure 4 of "Ann. Rep." represents the lower half of a leaf of same 

 character as that in "U. S. Geol. Rep.," I. c. 



ARAUCARIA, Juss. 

 Araucaria spathulata, Ne-wby. 

 "Notes on Ext. FL," p. 3; "Illustr.," pi. ii, figs. 5, 5a. 



Leaves close, broadly spathulate, obtuse, narrowed above the enlarged base, 

 carinate; medial nerve distinct at base, effaced from the middle upwards. — (Newby.) 



The author remarks that the specimen represents a fragment of a 

 branch nearly half an inch in diameter on which the leaves are thickly 

 set, their base slightly decurring scarcely separated from each other. 

 From their base the leaves, half an inch in length, radiate in all directions. 



The species is closely allied to Abietites curvifolius, Dkr., of the 

 Quader-sandstone of Blankenburg. This has the leaves rounded at the 

 apex, a deep medial nerve, and the leaf scars very distinct. This last 

 character is well marked on the figure of A. spathulata. The same figure 

 shows the leaves reflexed or spreading at the base, the only part seen. 

 In Dunker's species the leaves are curved up from the middle and are 

 longer.

TORREYA, Am. 



Torreya oblanceolata, sp. nov. 



Plate I, Fig. 2. 



Branches slender; leaves long, flat, gradually enlarging upwards from the decur- 

 ring base; medial nerve thin. 



The figure represents the best and largest of the fossil fragments.
