STT7R — COAL-PLANTS OF OSTOAVAN AND ROSSITZ. 7 



and some of them form links between different genera. The genus 

 Hipparion forms a link binding the genus Equus to the genus Rhi- 

 noceros ; for its members have small hoofs on either side of the prin- 

 cipal one, as in the latter genus, a peculiarity which has been ob- 

 served by several eminent naturalists in malformed horses. Accord- 

 ing to this view the malformation in the living horse would simply 

 be a recurrence to ancestral types of the early Pliocene and later 

 Miocene. The Ictitheriwn also is a link between the Hyaenidge and 

 the Yiverridae, and is considered by the author to be the ancestor of 

 all the diversified forms of the Hyaenidae. In like manner Rhino- 

 ceros pachygnathus has handed down its characters to two colla- 

 teral branches, R. simus and R. hicornis of Africa. In fine, the in- 

 termediate character of the fauna of Pikermi, allied on the one hand 

 to preceding Eocene and Miocene types, and on the other to more 

 speciahzed and more recent Mammals of the Pliocene and Pleisto- 

 cene epochs, as well as to those now hving, is considered by M. 

 Gaudry to be explicable only on the theory of descent with modifi- 

 cation, proposed by the author of the ' Origin of Species.' [W.B. D.] 



On ike Coal-Plants of Ostowan and Rossitz (Moeavia). 

 By Mr. D. Stur. 

 [Proceed. Imp. Geol. Instit. Vienna, April 1866.] 

 The deposits of these localities have lately been stated by Prof. 

 H. B. Geinitz to belong to the Carboniferous period, and to be 

 analogous to the strata of Wettin, Jlefeld, Stockheim, and Ebendorf. 

 The vegetable remains are distributed in them as follows : —
