MYRTACEAE. 

 Eucalyptus L'Her. Sert. Angl. i8. 1788. 

 There are about one hundred and forty existing species of 

 great variety of form, foliage and blossom, confined to the 

 Australian region, none occurring in New Zealand on the one 

 hand or Asia on the other.* Nine fossil species have been re- 

 ferred to this genus from American strata, most of which are 

 doubtfully determined owing to the uncertainty of leaf re- 

 mains : Island Raritan 2, Dakota 3, Raritan 4, Laramie i, 

 Green River i, Atane 2.

 This reference is only provisional, as the leaf is too frag- 

 mentary for certainty and the venation is entirely obliterated. 

 I have thought I detected the characteristic venation at times 

 but cannot be certain. Previously recorded from the Dakota, 

 Kansas ; the Raritan, Woodbridge, Sayreville, N. J. ; and the 

 Cretaceous of Staten Island, Long Island and Martha's Vine- 

 yard. Also recorded from Greenland and the continent of 

 Europe. 



Eucalyptus (?) dubia sp. nov. PI. 32./. i. 



This fragment is referred to Eucalyptus because of its 

 resemblance to Newberry's Fl. Amboy Clays, pi. 32. f. d, 



* Although Ettingshausen records them from the Tertiary of New Zea- 

 land (Trans. N. Z. Inst. v. 23).
