554 ON BATRACHIANS FROM THE CAUCASTS. [May 5, 
Male specimens (8 in number) have a large compressed dermal 
tubercle, pointed and directed forwards, on the base of the tail, 
just above the posterior border of the cloaca. This tubercle, 1 
suggest, may assist in clinging to the female during the pairing. 
Shining black above, with two more or less regular series of 
round, oval, or elliptical greenish-yellow spots; blackish brown or 
dark plumbeous grey beneath, with or without small greyish-white 
spots or dots; these small spots constantly present on the throat.

The lungs are short, as much developed as in S. maculosa. 
The skull is quite typical of a Salamandra, only not so broad as 
in S. maculosa and S. atra, There are 17 precaudal and 53 caudal 
vertebre, against 16 and 25 or 26 in S. maculosa.

This handsome Newt is now represented in the Museum by a 
fine series, consisting of 14 specimens from Brusa, Trebizonde, 
and Borshom in Transcaucasia. The dorsal crest of the males 
may be deeply toothed, as in JZ. cristata, which this Newt resembles 
in the shape of the head, the notch in the crest on the lumbar 
region, and the long, slender digits. A dermal fold runs along 
the outer edge of the crus and tarsus in the males. In the Traus- 
caucasian specimens the vertical black bars on the dorsal crest are 
of equal breadth; a whitish band extends along the middle of the 
muscular portion of the basal third of the tail, becoming wavy and 
broken up further down. 
The following measurements are taken from five specimens from 
Borshom :—

An outline figure of the skull has been given by Alfred Dugés 
in his paper on the Urodeles of France, in 1852. Otherwise 
nothing is known of the osteology of this species. I have there-
