_Lingua ovalis, integrâ, margine posteriore libero. Dentes palatini
utrinque in fasciculis duobus dispositis, quorum alter ad marginem
anteriorem narium interiorum, alter pone nares interiores, prope
arcum maxillarem. Nasus terminalis, truncatus, ultra labium
productus. Tympanum conspicuum, circulare. Cutis omninò lævis.
Digiti anteriores liberi, posteriores ad basin tantùm palmati._
The genus _Limnocharis_ is remarkable for the existence of palatine
teeth in a part of the mouth in which they have never been observed in
any other amphibian. Not only is there a small group or line of these
contiguous with the anterior margin of the posterior nares,—a situation
in which they are found in some other genera of _Ranidæ_, but there is
also a group of them placed at some distance behind the posterior margin
of these openings, and close within the rise of the maxillary arch. This
genus, of which one species only is at present known, will probably be
most naturally placed between the true _Ranæ_ and certain of the
_Cystignathi_.
