DESCKIPTION OF THE SIM'X'IES. 263 



Abietites ellipticus, sp. nov. ? 



Plate CXXXII, Figs. 8, 9; Plato CXXXIIl, Fif,'s.2-4 ; Plate CLXVIII, Fig. 8. 



Cones of medium size, elliptical in outline; scales thin, long, iinljri- 

 cated, and closely appressed ; axis thick. 



Locality : Fredericksburg. 



This cone is not uncommon at Fredericksburg. It is very much like 

 that of Ahks. In PI. CXXXll, Fig. 9, the upper surface of the cone has 

 been accidentally removed so as to expose the axis. This, towards its b.ise, 

 is very thick. The species seems to be of the same general character as A. 

 macrocarjiKS, but the cones are smaller and inucli shorter. 



Abietites angusticarpus, sp. nov. ? 



Plate CXXXIIl, Fig. 1. 



Cone oblong, very narrow in proportion to its length ; axis projjor- 

 tionally very thick and short ; scales short, comparatively thick at base, 

 thin towards the summit, imbricated, closely appressed. 



Locality : Fredericksburg. 



This was found in only one specimen, which, although imperfectly 

 preserved, is clearly different from the two previously described species. 

 It was evidently very narrow in proportion to its length, for the base and 

 summit are not preserved. The scales appear unusually thick at base as if 

 still inclosing the seed, and they are pro})ortionally very short. They have 

 been removed from the upper surface of the axis so as to show the scars 

 of insertion. 



ARAUCARITES Sternb. emend. 



Under this head I place certain fragments of cones that appear to be 

 more nearly allied to Araucaria than any other conifer, but whose true 

 place is doubtful. 



Araucakites Virginicus, sp. nov. 



Plato CXXXIV, Fig. 7. 



Cone obovate, rounded at the summit ; scales large, numerous, thick, 

 transversely subrhomboidal to nearly round, shield- shaped, umbonate. 

 Locality : Entrance to Trent's Reach.
