404 GEOLOGICAL SURVEY OF THE TERRITORIES. 



Platanus nobilis, Newb. 

 Eepresented by a large number of fragments. 



JUGLANS EUGOSA, Lsqx. 



Only an obscure special en. 



Oarpolithes osseus, sp. nov. 



Fruit hard, covered with a thin, bony shell, compressed, oval, rouud, 

 obtuse at one end, obtusely ijoiuted (?) at the other. 



The point is half destroyed. This fruit is 6 cent, long, 3 cent, wide in 

 the middle, irregularly narrowly striate in the length and rugose on the 

 surface. It has the form of a large nut, like those of some species of 

 Astrocaryum of the Palms. It is slightly flattened, apparently by com- 

 l^ression. 



Six miles above Spring Canon, near Fort JEllis. 



I have to i)lace in a single division a number of specimens marked 

 with three kinds of labels, for the reason that they represent some iden- 

 tical species from the different localities, and appear, therefore, as from 

 the same horizon. These labels are : " Near Fort Ellis, above coal ; A. 

 C. Peale, Jos. Savage." "Above Spring Canon, near Fort Ellis ; Jos. 

 Savage, W. H. Holmes.'' " Six miles above Spring Cahon ; A. (J. Peale, 

 Jos. Savage." All the specimens are of a very hard, metainorphic 

 shale, breaking across the plane of stratification, therefore, mere frag- 

 ments, rarely representing an entire leaf. Tlie localities are indicated 

 for the new or interesting species of this section. 



Gymnogramima Haydenii, Lsqx., Eept., (1871,) p. 295. 



Two specimens of this species, from above Spring Canon. 



Abietites dubius, Lsqx. 



Described formerly with specimens from the Eaton Mountains. The 

 specimens are from near Fort Ellis, above coal, and above Spring Caiion. 



Abies setigera, sp. nov. 



Leaves distant, simple, very narrow, needle form, in right angle 

 around and from the branches. 



These very narrow filiform leaves are 18 mill, long, less than one mill, 

 wide, linear sharp pointed, abruptly enlarged at the base in the point 

 of attachment to the branches, from which they diverge all around in 

 right angle. The leaves are nerved, channeled on one side, keeled at 

 the other. It has no relation to any fossil or living species known as 

 yet. 



Salisburia polymorpha, Lsqx., Ment. Jour. Science and Arts, (1859,) 



p. 362. 



Leaf fan-like in outline, tapering or wedge form to the base, divided 

 upward in lobes of various forms, either linear oblong obtuse or lance- 

 olate, short or deej)ly parted.
