924 ADDITIONS TO THE FOSSIL. (10) 
spp. of Zamenits occurring in our monarchy, I feel fully entitled to 
establish a new species upon it. 
The minute investigalion of the neighbourhood of Polgärdi would 
be desirable respecting Ihe validity of this species. 
Loeality : Polgärdi. 
10, Coluber Kormosi n. sp. 
(Plate XII, Figs. 4-8.) 
A promaxillary, a fragment of palatine, five pieces of maxillarv, 
two transversi, a fragmentary piece of basisph®noid, a basioceipital, 
and three quadrates. 
I establish on this material the new species, which is the nearest 
allv of Coluber longissimmus Laun. 
Comparing the pramaxillarv with that of Coluber longissimus, 
the following peculiarities eould be noticed: the anterior margin bent 
in a low arch, it is less carved out behind the two lateral processes, 
and Ihe two little processes arising at Ihe right and left side of pro- 
cessus nasalis are separated from the great process by a fine furrow. 
Processus nasalis softly widening upwards, in opposition to Lhat of 
(oluber longissimus, which is parallel. 
It is conspieuous on the palatine, that the llag-like'process (Plate XI. 
Fig. 5.) is bellter developed, this process originating in general by a wider 
basis out of the palatine, and its lateral margin is more upfolded. 
The characteristice marks of transversum are, that the handle of 
the bone is relatively longer, sliehtly bent, the zulf between the flag 
and the small thorn is less deep. 
The median furrow on the ventral side of basisphaenoid wider 
and much deeper than that of Goluber longissimus. 
Basioceipital is pentagonal. Its lateral processes are strongly 
developed. Near to the anterior margin of basioceipilal there are two 
protuberances, serving for adhesion of muscles. 
This protuberances are connected with a weak transverse keel. 
This keel has a continuation in the middle-line and bifurcates again 
before the condylus occipitalis like a-A. 
(Juadrates differs not from those of Goluber longissimmus. 
locality: Polgärdi. 
I named this new species to the honour of Mr. Turo. Koruos 
Ph. D. Roy. Hungarian Geologist, by the kindness of whom, I was 
able to study this material, and who has collected most of the remains 
here deseribed.
