BAILT PLANT-KEMAINS. 359 



it therefore very possible that fossil may have belonged to the same 

 genus*. 



A small cone is perhaps the fruit of the fossil I have figured as 

 Sequoia Du Noyeri, Fragments of other fossils such as that drawn 

 on PL XY. fig. 5, a & 6, I have referred to Cupressites, naming the 

 species C. MacHenrii ; the imbricated character due to the peculiar 

 arrangement of the leaves on the terminal branches is very evident 

 in some specimens, resembling very closely that of the ordinary 

 Cypress, Cupressus sempervirens. 



A large proportion of these fossils consists of leaves of Dicotyle- 

 donous plants, the principal varieties being shown on PI. XIV. Most 

 abundant amongst them are ovate and acuminate leaves, with entire 

 or non-serrate margins, and a simple character of venation (PL XIY. 

 figs. 7, 8) ; they resemble so nearly some of the species of RJiamnus 

 figured by Prof. A. Massalongo in ' Flora Possile Senigalliese, and 

 by Dr. Oswald Heer in ' Flora Fossihs Arctica/ as to induce the 

 belief in the probability of their generic identity, and of their having 

 belonged to trees or shrubs of the E-hamnacese or Buckthorn Order. 

 Some linear-lanceolate leaves, having entire margins and a strong 

 midrib, on which, however, no other trace of venation is perceptible 

 (PL XIV. figs. 3, 4), are so much like those figured by Massalongo 

 under the names of Olea and Andromeda, as to have probably be- 

 longed to the Order Oleaceae. 



A large ovate leaf (PL XIV. fig. 2) having an obsoletely serrated 

 margin is comparable with species of Fagiis figured by both Massa- 

 longo and Heer, approaching very closely to Fagus incerta, Massal.f 

 Other leaves (PL XIV. figs. 5, 6), tapering at each extremity and having 

 closely arranged ribs and a non-serrated margin, resemble some 

 forms of Quercus, such as Q. nereifolia, in * Flora Foss. SenigaUiese, 

 pi. 31. f. 6, and the evergreen oak, Q. ilex. 



ParaUel-ribbed stems or leaves of Endogenous plants, such as 

 may have belonged to Sedges or Grasses, are not unj&:equent in the 

 collection. 



A large mass of fossil wood partially oxidized was procured from 

 the bed with iron-ore ; it exhibits the structure very clearly, and is 

 evidently dicotyledonous J. 



Several fruit- or seed-vessels of different kinds, some of which are 

 shown on PL XIV. figs. 9-13, occur in the same bed, as weU as a few 

 remains of insects, two very small elytra or wing-cases of beetles of 



* Since the above paper was read, I find on looking into Sir Charles Lyell's 

 ' Elements of Geology,' sixth edition (1865), that in his account of the Isle-of- 

 Mull leaf-beds he mentions, on the authority of Professor Heer, Seqtcoia Langs- 

 dorfii as being the most prevalent conifer in those beds. The figures he gives of 

 that species on pp. 261 & 262 are so much like the fossil alluded to above, and 

 named by Forbes Taxites ? Campbelli, that it is doubtless the species he identifies 

 with S. Langsdorfii, and this is confirmatory of the remarks I had offered in the 

 above paper, before seeing this paragraph, as to the probability of its belonging 

 to the genus Sequoia.

i Since writing the above I have been enabled to examine this fossil wood 

 with the microscope and to make out distinctly its coniferous structure, as shown 

 in the enlarged representations, PL XV. fig. 3, a & J.
