Fa\(\\., and F. alpina, Poepp. etEndl., both indigenous to Chili, 

 liave been proved to be the most nearly related to the fossils 

 described. In the first the secondary nerves run to the points 

 of the serrations, in F. aljylna to the sinuations. As both 

 occur in tlie fossil species, this combination of characteristics 

 indicates clearly a connnon origin which the living species 

 have in tlie fossil species. The leaves of these descended 

 species are usually much smaller than those of the original 

 species ; sometimes, however, the leaf of F. proccra attains 

 perfectly the dimensions of the leaf of F. iilmifolia, as shown 

 by a specimen of a leaf from the herbarium in Kew Gardens. 

 The leaf of F. alpina attains a length of 33mm., and a breadth 

 of 13mm. (see Ettingsh. : Leaf - skeletons of the Apetahv, 

 Memoir, vol. xv., pi. viii., fig. G).

The fossil leaf (fig. 1) from Shag Point shows a remtirkable 

 approach on tJie one hand to the European Tertiary species 

 Fagns dcncalionis, and on the other hand to the North 

 \.vi\ex\ci\.n F. ferruginea. The secondary nerves are straight, 

 approaching each other, close together, and rather pro- 

 nounced. The tertiar}' nerves are not preserved. The serra- 

 tions agree with those of F. ninnisiana, and the shape agi'ees 

 perfectly with the leaf-fragment No. 6, mentioned by Unger in 

 the passage indicated.

In the locality named a few impressions of beech-leaves 

 were found in a sandy ferruginous rock, which, upon nearer 

 examination, were found to be distinguished by several charac- 

 teristics fiom those already known. To judge from the im-
