name in the ; Flora Tertiaria Helv." (vol. iii. p. 88 3 pis. 125 and 129), 

 and they would be better placed under Magnolia Liglefiddi, Heer. 



Corylus M(zcquarrii i Forbes, so very abundant in At nil. is probably 

 distinct from the Miocene 0. grosse-dcntata : while the single 

 smaller leaf, separated as Q. insignls. is only a smaller specimen of 

 whatever the larger ones may prove to be. 



The fragment referred to Li^uidainbar eurojj'Xv.m, A. Br,, has no 

 perfect digit, and the secondary veins are obliterated. The Green- 

 land Diospyros hracJiysejiala. A. Br., agrees with the form described 

 by Lesquereux from the Eocene Lignitic. but not with that of the 

 Swiss Miocene. 



Several distinct forms seem to be described under the name of 

 SaJisc Raeana, Heer, but only one of them recurs among the figures 

 of Baltic Miocene (?) plants. 



Quite a small fragment of a leaf and two indistinct fruits are 

 referred to Myrica acuminata. Enger : but they may belong to some 

 plant widely distinct from that of Sotzka or the Baltic floras, while 

 those placed by Lesquereux in the species are exactly like Quercus 

 Drymeia. The tiny leaflet called Ccilutea Salieri is very unlike in 

 all respects those figured in the ■ Flora Tert. Helv." ^ pi. 132. figs. 60 

 and 61). Papulus Zaddachi. Heer. is only represented from Green- 

 land by imperfect leaves, which probably may be identical with those 

 from the Amber-beds. The leaves from the Baltic, the American 

 Lignitic, and from Greenland, referred to Fraxinus dentievdata, 

 Heer, and those from Bovey Tracey, Missouri, and Greenland, 

 referred to Quercus Lydli. Heer, I believe in each case to be dis- 

 tinct forms. 



The foregoing species are all stated to be common to the Miocene 

 formations of Greenland, Europe, and America. Those which follow 

 are supposed to be confined to Greenland and America and Green- 

 land and Europe respectively. In the former category we have 

 Populus arcticus, Hr., and P. BicliarcUoni. Hr.. which I cannot dis- 

 tinguish from each other, from Greenland, Mull, and Eeading, with 

 leaves large and deeply notched, and from Am eric a .small and smooth, 

 or slightly notched. Hedera JIacClurii, Hr., is based upon such 

 fragments that comparison is impossible. The fine leaf. Vitis OVrilri, 

 Hr.. of Greenland, is not accepted by Saporta as a vine, and I do 

 not see justification for Lesquereux's association with it of -leaves 

 from the first and second stages of the Great Lignitic. The grounds 

 for separating specimens called Quercus Olafseni from those called 

 Oastanea Ungeri, Hr.. seem inadequate ; while neither of the three 

 very different leaves placed under Juglans dentievdata. Hr., agree at 

 all closely with the same species, according to Lesquereux. On the 

 other hand, the examples of Paliurus CoJombi of Heer and Les- 

 quereux appear to be properly united. 



Of the species common to Greenland and Europe, And r or, 'a 

 protogcea, Enger, and A. Saportana, Hr., are not identified in the 

 Greenland beds on adequate grounds. Acer otopterlv. Gopp., is 

 recognized from a fragment devoid of outline. The parts of leaves 

 assigned to Populus Gaudini, Fischer, might belong to J.i
