Identification. This species has the tympanum on the surface of the head, and therefore it lacks an external au- ditory meatus. The caudal, dorsal, and lateral ridges are weekly keeled, and the tail is slightly compressed. The oval disc in the lower eyelid is usually divided by a ver- tical groove into two sections. There are two rows of en- larged preanal scales, with the middle pair the largest, and there are eight longitudinal rows of ventrals.
