PLEURODELES, Michcelles. 



Char. — Head depressed; tongue small, rounded, covered with papillae entirely 

 posteriorly and upon the sides, attached in front, adherent in the middle ; pterygo- 

 palatine teeth in two longitudinal series, nearly touching anteriorly, extending a 

 considerable distance anteriorly beyond the internal nares, diverging so as to leave a 

 wide intermediate space, much broader posteriorly ; maxillary teeth small ; a bony 

 arch above the orbit ; parotids porous ; extremities slender as well as fingers and toes ; 

 first toe shorter than fifth ; skin granular ; tail compressed ; longer than body ; 14 

 pointed ribs on each side, sometimes perforating the skin.

One adult specimen in Mus. Acad. Nat. Sc. and two young (Bradybates poireti and 

 Triton nycthemerus) Dr. Wilson, Bonap. Collection. 



Qen. RemarJcs.— Pleurodeles is related to the Tritons, but differs from them in its 

 large flattened head, its lengthened ribs, its long tail ; the nares are more widely 

 separated than in the Tritons, the eyes more elliptical, the upper eyelid more de- 

 veloped, according to Michaslles. (Isis, 1830, p. 191.) The parotids are also wanting 

 in the Tritons. P. Watli is found abundantly in cisterns near Cadiz, in the south of 

 Spain. We have in the collection of the Academy a single specimen, labelled Triton 

 nycthemerus, belonging to the Bonap. Collection, which is without doubt the young 

 of Pleurodeles Watli. Gray observes that it is, perhaps, the young of T. marmoratus or 

 Triton cristatus, but the teeth are arranged as in Pleurodeles and not as in Triton, 

 and the tongue is also that of Pleurodeles, which is quite different from the tongue 

 of Triton- 



BRADYBATES, Tsch. 



Char. — Head round, occiput swollen, but the forehead depressed ; eyes small and 

 far apart ; feet very short, toes small, but free throughout ; body short, broad, the 

 the sides, as in Pleurodeles pierced by the ribs ; tail shorter than the body, broad at 

 the base, roundish, towards the end more angular, differing remarkably from Pleuro- 

 deles, inasmuch as the latter has a very long sword-like tail ; tongue small, rounded 

 like a firmly attached wart ; no parotids ; at the root of each foot two tolerably large 

 swellings. (Tschudi.)
