FLORA OF THE SHASTA FORMATION. 261 



Several impressions of cones were found at locality No. 1. The}- are 

 ovate-elliptical in form, with thin scales, the terminal ones being apparently 

 spatulate in shape. The fossils are so much like Abietites ellipticus Font., 

 from the Lower Potomac of Virginia, that there can be hardly any doubt 

 that it is the same species. 



PI. LXVIII, Fig. 14, represents a fragment of a stout twig with a cone 

 attached that now, owing to the fracture of the rock matter occurring 

 through it, is shown in section. This occurs attached on the right side of 

 the twig. There is on the left or opposite side of the same twig a portion of 

 another cone which was evidently originally attached opposite to the cone 

 first mentioned. In the same plane with the attachment of these two 

 cones there is visible on the twig a prominence indicating that a third cone 

 was once present. This, from analogy with the opposite cones first men- 

 tioned, probably had one opposite to it, so that the twig bore originally a 

 whorl of four cones.

Several specimens of cones were found in the Horsetown beds which 

 appear to be identical with the fossil cone Abietites macrocarpus, first 

 described by me from the Lower Potomac beds of Virginia. They appear 

 to have been long and cylindrical in form and to have had numerous thin 

 and closely appressed scales. 



The cone represented by PL LXVIII, Fig. 15, was found at locality 

 No. 2. It shows a stout axis with only the basal portions of some of the 

 scales preserved. The lower part of the cone is wanting and only the axis 

 of a portion of the upper part is present. The seeds, in part at least, seem 

 to be still present under the bases of the cone scales. They are well shown 

 on the left side of the axis. Thej^ are ovate-elliptical in form, narrowing to 

 the apex. The largest, probably because less compressed, is the lowest in 

 position. It is 2.5 mm. wide in its widest portion and 6 mm. long. 

 Another cone found at locality No. 1 and represented in Fig. 16 of the 

 same plate shows more of the original cone. In this the overlapping,
