290 GEOLOGICAL SUEVEY OF THE TEEEITOEIES. 



mucroiiate teeth. A few of these veins branch near the point as in Fagxis 

 Deucalionis, TJng. 

 Small fragments of Juglans and of Flatanus. 



11. Coalville, Ftah. 



A single specimen from this locality ; a piece of hard metamorphic 

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

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



12. Carbon Station, Union Pacific Eailkoad, Wyoming Tek- 



KITOEY. 



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



Plat ANUS acekoides, Gopp. A whole large leaf, far different from 

 the leaves of the following species by the borders rounded 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 Guillelm^, Gopp. Among others there is a large speci- 

 men covered with nearly entire leaves of this species, showing 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 HAYDENn, Newby. Same leaf as described from Medicine 

 Bow, p. 289. 



Carpolithes Cocculoides, (?) Heer, (Fl. Arc, II, p. 484, PI. lii, Fig. 9 

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

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

 or aclienmm, 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 Creek, Montana Territory. 



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

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



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

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

 mentioned as Fern from North 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 Heerii, sp.nov. We have numerous and well-preserved 

 specimens of this species. It agrees well enough with the small 

 forms of Sequoia Langsdorjii, Brgt., figured in Fl. Arc, I, PI. 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 

 round, slightly flattened, resembling the coae of S. Langsdorjii, iu
