 mens collected by I'm}'. Dana were examined by myself, and 

 are described more in detail in the Boston Journal of Natural 

 Eistory, vol. 7. No. I. The plants collected 1 . v the Kx. Expe- 

 dition comprised tlie following species, viz:

Of these Taxodium occidentaU is closely allied to T. dvbium 

 of the Miocene of Europe. The Glyptostrobus is apparently 

 identical with the European Miocene plant. Smilax cyclo- 

 phyUa is the analogue of «S1 orbicularis, while the Cirj>'inus and 

 Rhamnus are referred doubtfully to the European spech 

 which the names are given them. 



From the strata associated with the coal-beds of P.ellin<r- 

 ham Bay fossil plants had been collected by several persons, 

 but none had been described from thai locality until, in L859, a 

 series of specimens collected by Dr. Evans, Governmenl Geol- 

 I for Oregon, were placed in the handa of Mr. Lesquereux, 

 and described by him in the American Journal of Sciences, 

 (vol. xxvii. second scries, p. 359.) The following lisl includes 

 the species which arc possibly, bul nol probably, Tertiary, viz :
