406 On new Batrachians in the British Museum. 



A single male specimen from Brazil (exact locality un- 

 known), presented by Mr. L. Greening. 



Pelodytes caucasicus. 



Vomerine teeth in two transverse groups between the 

 choanre. Snout subacuminate, with moderately distinct 

 canthus; tympanum feebly distinct, two thirds the diameter 

 of the eye. First finger as long as second ; toes webbed at 

 the base and fringed ; subarticular tubercles strong ; a very 

 small inner metatarsal tubercle. The tibio-tarsal articulation 

 reaches the tip of the snout. Body covered with strong warts, 

 some of which are confluent into longitudinal folds ; a para- 

 toid-like fold above the tympanum. Olive above, white 

 beneath, all the warts covered with a black horny layer in the 

 male. Male with an internal vocal sac, the fore limbs very 

 strong, with rugose black plates as in P. punctatus ; similarly 

 with black rugosities round the lower jaw, on the breast, 

 belly, and under the hind limbs, especially on the subarticular 

 tubercles. 



From snout to vent 47 millim. 



A single specimen from Mount Lomis, Caucasus, 7000 feet, 

 received from the Tiflis Museum. 



This Batrachian is of particular interest as adding a second 

 species to the genus Pelodytes, the range of which was believed 

 to be confined to France, the Spanish peninsula, and North- 

 west Italy. Not long ago but three species of Pelobatoids 

 were known from the Palsearctic Region. The number is 

 now raised to five, viz. : — 



1. Pelobates fuscus, Laur. (Central Europe and North- 



ern Italy.) 



2. Pelobates cultripes, Cuv. (France, Spain, Portugal.) 



3. Pelobates syriacus, Bttgr. (Asia Minor, Syria.) 



4. Pelodytes punctatus, Fitz. (France, Spain, Portugal, 



N.W. Italy.) 



5. Pelodytes caucasicus, Blgr. (Caucasus.)
