Relationship.—It would appear that the relationship of this species is with Hyla bistincta, a widespread Mexican species likewise occurring in the same general area but at a much higher elevation. It also has an elongated flap which carries the anal opening nearly to the level of venter but the terminal part lacks the triangular flap. There is no prolongation of the snout tip. There are also numerous other differences, so that it would be difficult to confuse the two forms.

Remarks.—This adds another very distinctive species to the Veracrucian fauna. Despite the fact that this state has probably been explored at greater length than any other Mexican state it still is a likely place for the discovery of novelties.
