This consists of a constrictor and a dilatator muscle (men and mdn) and forms an effective apparatus very characteristic of adult amphibians (Bruner, '96 and '01, I. W. Wilder, '09). The naso-labial glands have to do with the terrestrial life into which the process of metamorphosis introduces the animal, in that they not only keep pliable the thin crescentic fold which by means of the contraction of the constrictor muscle closes the external naris against the entrance of foreign bodies, such as dirt when the animal is burrowing, but they also appear to have the peculiar int nip men.

Thus this water is prevented from entering the nasal passage when the animal, upon emerging from the water, reopens the nares by withdrawal of the crescentic fold. The nasal passages are by this means kept dry and fully.
