372 GEOLOGICAL SURVEY OF THE TEREITOEIES. 



Ixxx, Fig'. 3. The form is tbat of Myrica Schlechtenduli, Heer, Born- 

 staedt, FJ., PI. i, Fig. 7. 



UIJco Station., Nevada. 



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

 former ; collected and commuuicuted by Mr. S. W. Garmau. 



Sequoia angustipolia, sp. nov. 



Leaves short, imrrow, linear-pointed, e^Gct, or slightly apiiressed all 

 around the branches, decnrring at base. 



It is much like the small forms of Taxodium duhmm, as figured by 

 Ett., Bil. Fl., PI. xii, Figs. 3, 14, 15, with leaves, however, shorter and 

 decurreut. 



Thuya Garmani, sj). nov. 



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

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

 lioint, narrowing downward; in four rows. 



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

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

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

 leaves. As it is to T. sihirica what this varietv is to T. occidentalism it 

 may be cousidcied 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 species, represented only by a small branch, is like the large 

 forais of Taxodium dubium^ ditfering by exactly linear leaves, obtuse at 

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

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

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

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

 abruptly rounded and not enlarged at their huse. 



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. 



Eaton Mountains. 



The Thalassophytes described from this locality are all from the 

 Eocene sandstone underlying the lignitic strata. Except the species 

 of this class, none other has been added to those already known from 

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

 pp. 12 to 10. Tiie very hard metamorphic sandstone and shale contain- 

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

 little value for the paleontologist.
