290 GEOLOGICAL SUETEY OF THE TEREITOrjES. 



miicroiiate teetli. A few of these veins brancli near the point as in Fagtis 

 Deucalionis^ TJn^. 



Small fragments of Juglans and of Platanus. 



11. CoALYiLLE, Utah. 



A siDgie specimen from this locality ; a piece of hard metamorph:e 

 sandstone, with scattered, small fragments of dicotyledonous leaves, none 

 of which are large enough to be recognizable even for generic reference. 



12. Oaebon Station, Union Pacific Eaileoad, "Wyoming Ter- 



EITOEY". 



Fine-grained shale, same color and compound as at Medicine Bow. 



Platanl'S aceeoides, Gopp. A whole large leaf, far different from 

 the leaves of the following species by the borders rouDded to the petiole 

 and not tapering, by the angle of the secondary veins more open, and 

 by the form of the much broader leaves. 



Platanus Guillel3I^e, Gopp. Amoug others there is a large speci- 

 men covered with nearly entire leaves of this species, showiiig its vari- 

 ous forms. The leaves are all more or less trilobate, with short lateral 

 lobes ; the base is more or less open, cuneiform to the petiole and entire, 

 always descending lower than the base of the first pair of secondary 

 veins. The secondary veins are narrow, but well marked ; the texture 

 of the leaves is rather thin than coriaceous; the fibrilles somewhat obso- 

 lete, but in some leaves very distinct. Specimens of this species are 

 not distinguishable from the following. 



Platanus Haydenii, Xewbv. Same leaf as described from Medicine 

 Bow, p. 280. 



Caepolithes Cocculoides, (?) Heer, (Fl. Arc.,II,p. 481, PI. lii,Fig. 

 and 9 h.) A small obovatc fruit, obliquely truncate at its narrowed 

 base, about 1 centimeter long, nearly as broad, evidently a thick drupe 

 or achenium, as the stone is excavated around it on one side. It re- 

 sembles the fruit of an Acer, without the wing, or could be compared to 

 the fruit of a Prunus but for its unequal base, more contracted on one 

 side than on the other, much like Heer's figure, loc. cit. 



13. Sage Ceeek, Montana Teeeitoey. 



Fine-grained, buff-colored, hard, laminated shale, split in thin layers, 

 with few fragments of vegetable remains and some scales of fishes. 



A Feen, undeterminable fragments, of exactly the size and form as 

 the one published by Heer, (Fl. Arc, II, PL xlviii, Fig. 3 h,) and merely 

 mentioned as Fern from ISTorth Greenland. The surface is covered with 

 a pulverulent coaly matter, obliterating the nervation. The medial 

 nerve only is visible on our specimen, while it is not seen on the frag- 

 ments obtained from Greenland. 



Sequoia Heeeii, sp. nov. We have numerous and well-preserved 

 specimens of this si^ecies. It agrees well enough with the small 

 forms of Sequoia Langsdorfii, Brgt., figured in Fl. Arc, I, Ph ii. Fig. 15, 

 but differs evidently by shorter and narrower, more distant leaves, all 

 narrowed above the decurring base, and, as observed upon the same 

 branches, either pointed or obtuse. Some even are enlarged upward 

 and obtuse ; some abruptly pointed. The cone is borne on long, naked 

 branches, marked with undistinct scars of scales; its form is nearly 

 Tound, slightly flattened, resembling the cone of S. Langsdorjiij in
