1896.] BATRACHIANS FROM THE CAUCASUS. 553 
It will be seen that the new Frog agrees with its Western con- 
gener in the large frontoparietal fontanelle ; the absence of pala- 
tine bones; the very strongly dilated transverse processes of the 
sacral vertebra and the forward direction of the three anterior to 
them; the curved coracoids and precoracoids ; the bony style to 
the sternum; the fusion of the two outer bones of the second row 
in the carpus; and especially in the fusion of the astragalus and 
calcaneum to a single bone, resembling the fused radius and ulna 
or tibia and fibula of tailless Batrachians. 
[Since the reading of my paper, I have received, July 24th, 
through the courtesy of the author, M. Nikolski, a copy of the 
description of a new Pelobatoid, named Pelodytopsis caucasica. 
The genus and species are established on two female specimens 
from Lagodekhi, Transcaucasia, obtained by M. Mlokossewicz, 
apparently the same collector who first discovered Salamandra 
caucasica. This Frog is no doubt the same as my Pelodytes cauca- 
sicus, which has priority, M. Nikolski’s paper being signed June 
1896. There is no foundation for the new genus, the species 
being, as I have stated above, very closely related to Pelodytes 
punctatus. |

Thanks to Dr. Radde, the British Museum now possesses a good 
series of specimens of this rare Salamander, from Mount Lomis, 
7000 feet, from which the following description is drawn up. 
The series of palatine teeth extend forwards far beyond the 
choane ; they converge and are narrowly separated from each 
other in front, after being angularly bent and enclosing a rhom- 
boidal space ; in the middle the series are closely approximate and 
parallel; behind they strongly diverge again; in some specimens 
the angular bend does not exist and each series may be described 
as S-shaped. 
The tongue is large, covering nearly the whole floor of the 
mouth, free at the sides only. 
The head is much depressed, and the eyes moderately large and 
prominent; the snout is semicircular in outline and does not 
project beyond the lower jaw. The parotoid glands are flat, not 
sharply limited as in the other species of the genus. A strong 
gular fold is present. 
The body is much elongate and feebly depressed, with 12 strong 
costal grooves between axilla and groin; tle skin is quite smooth 
and shiny, without any warts. 
The limbs meet or slightly overlap when pressed against the 
body. ‘The digits are moderately elongate and depressed ; the first 
toe is the shortest, the fourth the longest, slightly longer than the 
third, the fourth and fifth are equal. The tail is subcylindrical, 
slightly compressed, and longer than head and body.
