JURASSIC FLORA OF DOUGLAS COUNTY, OREG. 139 



Carpolitiius oregonensis Fontaine n. sp. 

 PI. XXXVII, Figs. 10, 11. 

 Two large nut-like objects were found, one each at localities Nos. 1 

 and 7. They seem to be the same species. They are not unlike the 

 seeds of Ginkgo hiloba, but are much larger. They are broadly ellip- 

 tical in form and are smooth on the surface and rounded at both ends, 

 which do not differ in form. They are quite convex, but the original 

 surface seems to have been removed. 



The form given in PI. XXXVII, Fig. 10, is 4 cm. long and 27 mm. 

 wide in its widest part. That given in Fig. 11 is 37 mm. long and 27 

 mm. wide. 



Carpolithus elongatus Fontaine n. sp. 



PI. XXXVII, Fig. 12. 

 A single specimen of a narrowly elliptical nut-like object was 

 obtained at locality No. 7. It is the same type of plant as Carpolithus 

 oregonensis, but is smaller and proportionally much narrower. The 

 surface is smooth. It is slightly unsymmetrical, one longitudinal mar- 

 gin being more convex than the other. This may be due to distortion. 

 Its full length is not preserved, but it is still 39 mm. long and 16 mm. 

 wide. It was probably over 4 cm. in length, giving a great length in 

 proportion to its width. 



Carpolithus douglasensis Fontaine n. sp. 

 PI. XXXVII, Fig. 13. 

 A single specimen of a pecuhar pod-like organism was found at 

 locality No. 19. It is not convex, but lies even with the surface of the 

 rock and does not seem to have had much woody matter in its com- 

 position. It has at one end, the probable base, what looks like a frag- 

 ment of the stem to which it was attached, and at the opposite end 

 an apparent double beak, as if it were a two-valved pod. The length 

 is 2 cm. and the width in the widest part 1 cm. It is elliptical in form, 

 narrowing gradually from base to apex. Whatever it may be it is 

 certainly different from any of the previously described nut-like objects. 

 I name it from Douglas County, in which it was found.
