In addition to the great number of Miocene species, whose origin 

 can apparently be traced back to the Eocene, there are not wanting 

 indications that certain Miocene genera were not completely differen- 

 tiated into genera in the Eocene period. For instance, the genns 

 Castanea, perfectly developed in the Miocene, seems to be represented 

 in the Eocene by a Castanea-like oak, Q. Bournensis, which combines 

 in itself characters common to both genera, which are no longer found 

 united. Another example is afforded by a Pomaderris-like Rhamnus, 

 which, in like manner, seems to show the commencement of the differen- 

 tiation of Pomaderris from Rhamnus, completed in the Miocene Flora, 



I have selected for mention a few from among a great number of 

 new forms, as possessing special interest. 



A very distinct Marattia, nearly allied to M. Kaulfussi, J. Smith, is 

 remarkable as being the first species met in the Tertiary. The Celtis 

 is allied to 0. Japeti of the Miocene Flora of Parschlug on the one 

 side, and to the living C. australis on the other. 



The only Adenopeltis is allied to an American living species. The 

 presence of two species of Banksia is ascertained beyond all doubt, 

 since their seeds also occur ; many other leaves formerly named 

 Banksia I now agree ma,y belong to Myrica. The proteaceous 

 Lomatia is represented by a fruit. Yery characteristic leaves of 

 Aristolochia and of Alyxia allied to the living Alyxia spicata R. 

 Brown, and a Clerodendron allied to the East Indian C. viscosum 

 Vent, are found, but rarely. 



Of Diospyros is found calyx, berry and leaf, the berry occurring 

 also in Sheppey. The solitary species of Diospyros of Alum Bay and 

 that of Sheppey are the same. The only species of Cornus is remark- 

 able as showing perhaps a genetic relation with some of the Miocene 

 species. The leaves of two species of Malvaceae belong, I think, to 

 two of the species of Hightea from Sheppey, where eight species are 

 found. One of the very characteristic leaflets of Bombacees may 

 belong, on account of its venation and form, to the Brazilian genus 

 Salmalia ; and very characteristic leaves of Ternstrcemia, nearly allied 

 to a Miocene form, are found. Of Cupania, the fruits of eight species of 

 which are found at Sheppey, I have distinguished six species by their 

 leaves in Alum Bay, and these I provisionally refer to the nearest of 

 the Sheppey species. The only Alum Bay Pistacia is nearly allied to 

 the well-known P. vera. The putamens of two species of Prunus, of 

 which one is common to Sheppey occur, and of Amygdalus three 

 species of fruits are found. 



Of the Papilionaceee I could distinguish thirty-eight species belong- 

 ing to ten genera. The richest are Cassia and Dalbergia, and many 

 species of them are also found in Hairing and Sotzka. 



The comparison of the Fossil Flora of Alum Bay with that of 

 Bournemouth and with the other Tertiary Floras is reserved until
