THE GEOLOGIST. 



in the caves of N. Bohemia. One single cave near Theissholz (W. 

 Hungary) afforded remains of bears, wolves, foxes, martins, and 

 hyaenas — Imp. Geol. Institute, Jahrbuch, 1858, Verhandlungen, 

 p. 147) ; another cave in Hungary contains a remarkable quantity of 

 Felis spelcea. The real cause of these great numbers is, however, that 

 these caves were once the retreats of these animals, where for a 

 number of subsequent generations their remains were accumulated. 

 Carnivora are notably scarcer in the diluvial Loam (Loss) of the 

 plains ; and what I myself saw in such localities is little better than 

 some few fragments. 



Besides some loose teeth from the marine littoral deposits of 

 Nussdorf, near Vienna (referable, as M. H. von Meyer remarked 

 many years ago, to four different species, one of them probably insec- 

 tivorous, but insufficient for accurate determination), and an anterior 

 half of a lower jaw from a Mammal (probably referable to the family 

 Canidce), out of the lignite of Eibiswald, kindly communicated to me 

 by Professor Oichhorn, I know only three species of Tertiary Carni- 

 vora existing in Austria, and these are Machairodus cultridens (one 

 individual), Hyaena Hipparionum (two individuals), and Amphicyon 

 intermedins (one individual). 



Machairodus cultridens. 



The only remains of this large and powerful Carnivora known by 

 me to have been found in Austria is an upper angular tooth from 

 Baltavar, perfectly agreeing with the previously described specimens 

 from Epplesheim and Pikermi. It may be, therefore, sufficient for 

 me to notice a peculiarity left unmentioned by other descriptions. 

 The ex-denticulated external edge is notably inclined towards the 

 inner side of the tooth beneath the upper end of the crown, as indi- 

 cated in Professor Owen's British Foss. Mammalia, p. 180, fig. 69, on 

 the right. Isolated tubercles appearing first on the middle line of 

 the opposed side, at last join upwards in forming a second denticulated 

 edge ; a slight trace of denticulation is likewise traceable near the 

 middle line itself. The same particularities have been noticed by 

 Professor A. Wagner in the teeth from Pikermi, preserved in the 

 Museum of Munich. The localities of Machairodus cultridens hitherto 

 known, are Eppelsheim, Pikermi, the Arno Yalley, and Baltavar. The 

 tooth found in this last-named place is in M. de Schwabenau's col- 

 lection at Oedenburg (Hungary). 



Hymna Hipparionum, Gervais. 



The remains of this species, the first representative of the genus 

 Hyama on our globe known to occur, have been discovered some in 

 Austria, and two halves of lower jaws found at Baltavar ; the one is 

 in the Vienna Imperial Museum, the other in M. de Schwabenau's 

 collection. Among the Pikermi fossils presented by Baron Breuner-
