tion. Besides differing by the form of the leaf, the secondary veins are 

 thicker and flat, and the nervilles scarcely distinct. 



Khamnus acuminatifolius (?), Heer, Fl. Tert. Helv., Ill, p. 81, PI. 



cxxvi, Fig. 3. 



A fragment only, with the point and the base of the leaf destroyed. 

 The form of the leaf and its nervation agree with the author's figure and 

 descrij)tiou. It differs much from the other species described above. 



Ehamnus EECTmERVis, Hecr, Eept., (1871,) p. 295. 



It is not frequent at Golden. We have only a few specimens from the 

 ■white sandstone. 



JuGLANS EHAJViNOiDES, Lsqx., Eept, (1871,) p. 291. 



Sparingly represented at Golden. 



JUGLANS EUGOSA, Lsqs., Supt., p. 10. 



Found in more numerous and better preserved specimens than the 

 former. 



JUGLANS (FICUS ?) SmITHSONIANA, Lsqx., Supt., p. 16. 



The leaf referable to this species merely differs from the one pub- 

 lished irom the Eaton, by the less tapering base, which is n)ore abruptly 

 attenuated to a broad petiole, a difference scarcely noticeable. 



JUGLANS SCHIMPEUI, Lsqx., Supt., p. S. 



The specimens of Golden have the same characters as described. The 

 peculiar form of the leaves identifies them easily. 



Carpolithes palmarum, Lsqx., Supt., p. 13. 



A number of fruits of the same size and form as those from the Eaton 

 Mountains. They are not striated, however, and rather coarsely 

 wrinkled. They may represent a different species. 



Beside the leaves described from Golden's specimens, I found still 

 there a stipule of Platauus, a leaflet, square in outline, 2i cent, wide, 

 acutely shorr-lobed at the two upper corners, truncate at base, without 

 visible nervation. It is apparently referable to Flatanus Haydcnn. 



A number of iJagments of uncertain affinity, or whose character 

 could not be recognized ; among them, leaves doubtfully referable to 

 Alnus Keferstcinii, Gopp, others to Rhammts Dcchenii, Web., and still 

 others to Ginnamomum Mississipiense. Lx., have been obtained from the 

 same locality by Prof. B. F. Meek. 



31arshalVs Estate, Boulder Valley. 



Specimens of fossil plants are here found, either in clay-beds, where 

 the fragments are heaped and mixed together in a mass of unrecogniz- 

 able forms, or in a coarse sandstone, where the details of nervation are
