arise in bundles of from two to five 5 and the scales of the 
cones are thickened, and terminate in discs more or less 
defined. In Firs, (Larch, Cedar, &e.) the scales have thin 
edges, and the leaves are solitary.

Several cones with the above characters have been found in 
the Wealden formation. A cone figured and described by 
Dr. Fitton, is remarkable for a double prominence on each 
“Scale: it was supposed to resemble the fruit of Dammara, 
but the strobilus of the latter is like that of the Cedar of 
Lebanon, in which the edges of the scales are thin. The 
Wealden fossil appears to be a genuine pine, and may be 
_ distinguished by the name of its discoverer, Pinites Littoni ; 
_asmall figure of the only known Specimen is given, Wond.

__ Lhave collected from the Wealden strata of the Isle of 
_ Wight three or four small cones, which resemble those of a 
‘Species of Araucaria ; they are ovate, imbricated, with 
acuminated scales, which are recurved at the apex. The 
fossils figured in Wond. p. 399, fig. 2 and 3, are, I believe, 
“water-worn specimens of the same species. *
