1898,] comsTT m. g. peracca on an Italian newt. 483 



gives me the opportunity o£ making my new species better known 

 and to add something to my previous remarks. Specimens are 

 also now exhibited in the Society's Eeptile-house. 



MoLGB italica Peracca. (Plate XL.) 



Triton tceniatus (partim), H. Giglioli, " Elenco del Mammiferi, 

 degli uccelli e dei Eettili ittiofagi appartenenti alia fauna italica e 

 Catalogo degli Anfibii e dei Pesci italiani " (estratto del Catalogo 

 generale della sezione italiana alia Esposizione internazionale della 

 pesca in Berlino, nell' anno 1880) (spec, of Pahzzi). 



Triton vulgaris, subsp. merklionalis (partim), Camerano, Mono- 

 grafia Anfibi urodeli italiani, 1884, Mem. Eeale Ace. delle Scienze 

 di Torino, ser. ii. torn, xxxvi. (spec, of Campobasso). 



Eronto-squainosal arch partially ligamentous ; frontals with 

 well-developed, thick, orbital processes. Palatine teeth in two 

 series in contact or hardly separated anteriorly, then gradually 

 diverging behind ; the two diverging branches often somewhat 

 curved inwardly ; these series commencing on a line with the 

 choanse. 



Tongue small, elliptical, free along the sides (as in M. vulgaris). 

 Head thick, swollen in the parotoid region, longer than broad, 

 once and a fifth as long as wide, contained thrice in the length o£ 

 the body. The greatest width of the head at the centre of the 

 eyes in the males, at the commissures of the mouth in the females. 

 Upper surface of the head slightly convex, but nearly in a straight 

 line seen from the side ; a short and hardly defined groove on the 

 ethmoidal region ; no lateral grooves. Snout thick, short, obtuse, 

 with ill-defined canthus rostralis, broadly convex between the eyes 

 and the end of the snout. Eyes slightly prominent, especially in 

 the males, the longitudinal diameter of which equals the distance 

 between the anterior corner of the eyes and the nostril. Inter- 

 orbital space contained twice and two-thirds, never thrice, in 

 the length of the head. Labial lobes well developed during 

 the breeding-season, very much developed in old females. Body 

 quadrangular in the breeding male, with a more or less developed 

 cutaneous fold bordering each side, without dorsal crest and sub- 

 quadrangular in the female, with a distinct median dorsal groove 

 in both sexes. Limbs moderate ; the fore limb stretched forwards 

 extends just beyond the tip of the snout in the males and hardly 

 reaches the tip of the snout in some females. 



When the limbs are adpressed, the third finger in the male over- 

 laps the outer tarsal tubercle, in the female it hardly reaches the 

 base of third toe. The length of the fore and hind limbs is the 

 same in both sexes, Fingers and toes moderate, depressed ; the 

 latter in the male often with rudimentary web at the base. Two 

 small, but very distinct, conical carpal and tarsal tubercles, the outer 

 of which, especially the tarsal, is more prominent. Tail strongly 

 compressed ux the breeding-season, a little longer than head and 

 body in the male, equalling head and body in the female, with an 

 upper and a lower crest. The height of the tail is less in the
