3. Pelobates robustus n. sp. 
(Plate XI, Figs. 1—5.) 
Eight fragmentary pieces of maxillary, a pair of pramaxillary 
and 4 angulare are left from the skull. 
This species exceeds in size the largest specimens of Pelobates 
cultripes Guv. 
. Maxillary is not covered with osteoderms in such great extent as 
that of Pelobates eultripes, being the under half of maxillary quite 
smooth. Characteristie is the furrow, which originates at the posterior 
margin of orbit and divides in two branches, the one stretching for- 
ward, the other backward. 
This bifurcated furrow divides the osteoderms in two parts. 
The pr&maxillaries differs from those of Pelobates cultripes in 
the peculiarly depressed form of the ascending processes. 
Processus coronoideus of angulare is carved out like a spoon. 
From the hyoid apparatus the only remain is a thyreoid process. 
The pelvie girdle is represented by an ileum, on which we may 
clearly observe the characteristic marks of the genus Pelobates viz. 
the total absence of tuber superior, and the presence of a canal exten- 
ding from the inner margin of ileum, through the neck of ileum till the 
acetabulunn. 
The only remain of posterior extremily is an os cruris. 
Locality: Polgärdi (pannonian filling of a hole on the Bänyahegy). 
4. Pelobates sp. 
There are yet in the collection 3 ileums, which belong without 
doubt to the genus Felobates Regarding the great difference which 
exist between the Beremend, Püspökfürdö fauna on one hand, and 
between the Polgäardi on the other, I dare not determine this ileums 
as Pelobates robustus By., therefore I denote it as Pelobates sp. 
I think however that Ihe remains! stand nearer to Pelobates 
robustus By., than to the recent Pelobates fuscus Laur. 
Locality: Beremend (praglacial red clay witlı bean-ore), Püspök- 
fürdö (praeglac. red sand with stone-fragments). 
I Especially the Beremend ileum.
