ramification, form, aud direction of leaves ag-ree with the species as it is 

 represented by Heer from specimens of the Upper Oretaceons of Green- 

 land, and especially as it is figured in the Moletin Flora by the same 

 author. Schimper admits as a synonym of this species Frenelites 

 Beiehii, Ett., to which Ghjiitostrobm gracilUmus of the Cretaceous Flora 

 was compared, and supposed to be identical. This last species would, 

 therefore, be referable also to this Sequoia. Its generic relation is indi- 

 cated, indeed, by the scales of a cone found upon the same specimen and 

 figured in PI. I^ fig. 8, and the specific affinity by the fastigiate rami- 

 fication. Now this so-called Glyptosirohus has its stems and branches 

 still more slender, and its leaves still smaller than Sequoia condita, and 

 if it is referable to S. fastigiata, the new Sequoia, whose cones are 

 similar to those of S. fastigiata, has nothing of a different character to 

 separate it but its ramification. The question may be settled by the 

 discovery of more complete specimens. 



4. Sequoia subulata!, Heer. 



Branches erect ; brauchlets filiform ; leaves narrow, subulate, decur- 

 rent at base, erect or falcate. 



Of this form we have a mere branchlet, which, but for its narrow sub- 

 ulate leaves, could be referred to Sequoia Reielienhaclii, Heer. Like the 

 former, its exact relation is still uncertain. 



5. PiNUS QuENDSTEDTi, Heer. 



Leaves by five, very long and narrow, filiform, nerved in the middle ; 

 cones long, subcylindrical ; surface (apophise) of the scale broadly 

 rhomboidal ; central mamilla round. 



This species is represented by a number of specimens from Fort 

 Harker. They are fragmentary ; but the form of the long subcylindri- 

 cal cones, that of their scales, and the extremely narrow, concave, nerved 

 leaves, are all unmistakable characters which identify this species 

 with that of Moletin. 



6. Inolepis?, s-p. 



Small round cone or fruit attached to a branch mixed with undeter? 

 minable remains of Conifers. The impression of the large body is deep- 

 semi-globular, indistinctly marked from the point of attachment to near 

 the top by five obtuse costic, or narrow ribs, coming together and disap- 

 pearing below the top. The other fragments, on the same branch and 

 above this, appear like scales of a small open cone. This may be com- 

 pared to the part figured in the Artie Cretaceous Flora of Heer (vol. 

 Ill, PI. XVI, fig. 16), in supposing that it represents a cross-section of 

 a small cone seen undeveloped and entire upon our specimen. These 

 remains have been figured for a future elucidation by better preserved 

 specimens. 



7. Myrica cretacea, sp. nov. 



' Leaves long, linear-lanceolate (point broken), gradually narrowed 

 downward to a short thick petiole; middle nerve thick; lateral veins on 

 an acute angle of divergence, ramified, the branches anastomosing with 

 intermediate tertiary shorter veins, camptodrome; borders minutely 

 serrate; substance subcoriaceous ; surface polished. 



Comparable by the acute angle of divergence of the veins to a number 

 of species of j\lyrica of the Lower Eocene of Europe, aud also more 

 doubtfully referable to Lomatia.
