closely appressed scales hide the axis. The upper portion and termina- 

 tion of this cone are preserved, but the basal part is wanting. The part 

 preserved is a little over 2 cm. wide and 52 mm. long. As this is a mere 

 fragment, the original cone must have had a very considerable length.

A single imprint of what seems to be an immature cone, or partially 

 developed fertile catkin, was found at locality No. 11. It is elongate- 

 elliptical in form and shows the axis with several thin scales attached. It 

 has a length of over 1 cm., with the tip not preserved. This fossil has 

 more of the character of a cone of Abietites than any other conifer, but 

 with so small an amount of imperfect material the precise character can 

 not be determined. 



Genus PINUS Linnteus. 



PiNUS shaste:nsis Fontaine n. sp. 



PI. LXIX, Figs. 1-.3. 



A considerable number of specimens of what seems to be a new 

 species of Pinus were found at locality No. 1. This occurs in Shasta 

 County, Cal., IJ miles north-northeast of Horsetown, and the plants are 

 obtained from t5'-pical Horsetown beds, occurring mostly in loose bowlders. 

 Many of the specimens show that the leaves were attached to the stems. 

 Most of the stems that are indicated are bits of twigs that are very stout 

 as compared with the leafy twigs of fossil conifers that are usually found. 



The stem shown in PL LXIX, Fig. 1, is somewhat compressed by 

 pressure, but still retains nearly its original cylindrical form and is 1 cm. 

 wide. It shows projections more or less cylindrical in shape scattered 

 over the surface. These correspond to the insertions of the leaf bundles. 

 They seem to be a characteristic feature of the stems, for other specimens 

 that are imprints of stems show pittings that correspond to them. The 

 number of leaves in a bundle could not be determined. The}' show in the 

 best-preserved specimens a single pretty strong nerve, but most of the 

 imprints had evidently been more or less macerated before their entomb- 

 ment in rock material, and some of these give vague indications of there
