has been arnved at from a consideration of the sections which have 

 been described is, that not only does this new Tertiary stage fill up a 

 depression of the calcareous formation in the environs of Mons, but 

 that it extends more to the west in the valleys of the Haine r.nd 

 Trouille, below the Landenien sands and ancient alluvium which 

 occupy a large portion of those valleys. [A. S.] 



On the Fossil Flora o/ErBCEA. By Prof. ^'^'^GEE.

The richest locality of fossil plants in this island is Kumi, where 56 

 species, for the most part new, were collected in 1860 in a few days. 

 Since then several thousand specimens have been obtained from the 

 same locality, and the number of species has increased to 114. The 

 deposits in which they occur, like those of Pikermi, in Attica, well 

 known for the abimdance and variety of mammalian remains yielded 

 by them, belong to the upper portion of the Middle Tertiary series. 

 The vegetable remains from the Marls of Kumi may be supposed to 

 have belonged to species which grew on the ^gean continent (now 

 the uiEgean Sea), at the time when the mammals of Pikermi lived on 

 its surface. The greater number of the 51 mammalian species hitherto 

 stated to be represented among the fossil fauna of Pikermi are Carni- 

 vora, Euminants, and Pachyderms. The living species coming next to 

 them, as the spotted Hyaena, the two-horned Ehinoceros, the Zebra, 

 the Gii'afFes, and many Antelopes, are peculiar to the African fauna, 

 so that the later Middle Tertiary mammalian fauna of Greece must 

 have been impressed with a decidedly South African character. Among 

 the 114 vegetable species of Kumi, 47 (above 40 per cent.) are most 

 nearly allied to forms nowKving in South Africa and in the Cape region. 

 The genera Euclea, Eoyena, Rhynchosia, OmjjJialobium, the Myricece, 

 and the Proteacecp, represented in the flora of Kumi, strikingly re- 

 mind one of the present Table-land and Port-]N^atal flora.

On Fossil Insects. By Dr. Mate. 

 [Proceed. Imp. Geol. Inst, Vienna, February 19, 1SG7.] 



The author has examined the collection of Formicina from the 

 Tertiary Shales of Eadoboj, Croatia, in the Museum of the Imperial 

 Geological Institute, which had been named according to Prof. Heer's 

 determinations. This examination has proved Formica ohem liado- 

 hojana, Heer, to be the male, and Myrmica pusiUn, Heer, to be the 

 female of a species of G^copliylla, a genus spread over the whole 

 tropical zone in the Old World and in Australia. The Ponerce, 

 Heer, are partly Formicidcv, and partly Myrmickhf. Three new 

 species, Z/omefo29i<m antiquum, Hypodinea Haueri , and Lonchomyrmex 

 (a new genus) Freyeri, have been made known by Dr. Mayr.
