372 GEOLOGICAL SUEVEY OF THE TEERITORIES. 



Ixxx, Fig. 3. The form is that of Myrica ScMecJitendaU, Heer, Born- 

 staedt, Fl, PI. i, Fig. 7. 



MJco Station, Nevada. 



Specimens on the same kind of soft laminated clay shale as the 

 former 5 collected and communicated by Mr. S. W. Garman. 



Sequoia angustipolia, sp. nov. 



Leaves short, narrow, linear-pointed, evQct, or slightly appressed all 

 around the branches, decurring at base. 



It is much like the small forms of Taxodhmi duMum, as J&gured by 

 Ett., Bil. FL, PI. xii, Figs. 3, 14, 15, ^Yith leaves, however, shorter and 

 decurrent. 



Thuya Garmani, sp. nov. 



Branchlets short, alternate along a primary branch, of the same 

 thickness ; leaves nearly round, inflated, and marked by a gland at the 

 point, narrowing downward; in four rows. 



The specimen is small but very distinct ; no remain of cone has been 

 found. Its nearest affinity is with Thuya sihirica, Hort., a var. of 

 Thuya occidentalis, L., differing by shorter, more obtuse, more inflated 

 leaves. As it is to T. sihirica what this variety is to T. occidentalis, it 

 may be considered as a parent form of our present species. 



Abies Nevadensis, sp. nov. 



Leaves two ranked, horizontally spreading, 1 cent, long, 2 mill, wide, 

 linear, abruptly pointed, obtusely narrowed at base to a short petiole, 

 broadly nerved. 



This s])ecies, represented only by a small branch, is like the large 

 forms of Taxodium duhium, differing by exactly linear leaves, obtuse at 

 both ends, larger size of branches and leaves, &c. From Taxites olrilci, 

 Heer, Arct. FL, PL Iv, Fig. 7, it differs, too, by linear, shorter, more 

 horizontal leaves. Its nearest affinity is with our living AMes Cana- 

 densis, Mich., being only slightly more robust and the leaves more 

 abruptly rounded and not enlarged at their base. 



Salix elongata, O. Web. Pal., p. 63, PL ii, Fig. 10. . 



The base of the leaf is broken; the part left, 11 cent, long, exactly 

 corresponds in size and nervation with the upper part of Weber's figure. 



Baton Mountains. 



The Thalassophytes described from this locality are all from the 

 Eocene sandstone underlying the lignitic strata. Except the species 

 of this class, none otlier has been added io those already known from 

 specimens obtained formerly by Dr. Hayden and described in Supt., 

 pp. 12 to 16. The very hard metamorphic sandstone and shale contain-^ 

 iug plants breaks under the hammer in irregular small fragments, of 

 little value for the paleontologist.
