crenated ; largest upon the lower jaw, and all, apparently, un- 

 attached to the bone, but united to the gum, and admitting of a 

 depression backwards. Vomero-palatine teeth inconspicuous ; dis- 

 posed upon an obtuse-angled triangle, behind the inner nostrils, which 

 consist merely in a notch in the posterior edge of the palatine floor. 

 Sphenoid teeth in two elongated and approximated patches. Tongue 

 large, cordiform, attached along its median line only. Eyes, large and 

 prominent. Limbs, rather slender ; four fingers and five toes, slender, 

 free, and terminated by a small rounded callous disk. Tail, subcy- 

 lindrical, slightly compressed and attenuated. Skin smooth and soft.

OBSERV. The affinities of this genus will place it near Pletliodon, in 

 a natural method, perhaps, even between the latter and Desmognatltus.

DESCR. The head is elongated ; very much depressed, flattened, 

 and, when viewed from above, has almost an elliptical appearance. 

 The snout is very prominent, protruding beyond the lower jaw. The 

 nostrils are elevated ; lateral, subterminal, and far apart. The eyes, 

 very prominent ; their diameter enters only once in the distance 

 between their anterior rim and the extremity of the snout. The
