THE GEOLOOIST. 
in the caves of N". Bolaemia. One single cave near Theissliolz (W. 
Hungary) afforded remains of bears, wolves, foxes, martins, and 
hysenas — Imp. Geol. Institute, Jahrbuch, 1858, Verhandlungen^m 
p. 147) ; another cave in Hungary conta,ins a remarkable quantity of' 
Felis sjyelcea. 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 Yienna (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 Ilachairodus cultridens (one 
individual), Hycena HippoHonum (two individuals), and Amphicyon 
intermedius (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 th( 
inner side of the tooth beneath the upper end of the crown, as indi- 
cated in Professor Owen's Biitish Foss. Mammalia, p. 180, fig. 69, oi 
the right. Isolated tubercles appearing first on the middle line 
the opposed side, at last join upwards in forming a second denticulate 
edge; a slight trace of denticulation "is likewise traceable near th( 
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 Valley, and Baltavar. The 
tooth found in this last-named place is in M. de Schwabenau's col- 
lection at Oedenburg (Hungary). 
Hycena Hipparionum, Gervais. 
The remains of this species, the first representative of the genua 
Hycena on our globe known to occur, have been discovered some in 
Austria, and two halves of lower jaws found at Baltavar ; the one 
in the Yienna Imperial Museum, the other in M. de SchwabenauV 
collection. Among the Pikermi fossils presented by Baron Breunei
