This tree frog has a red iris similar to many species of the genus Phyllomedusa. The latter is merely a Hyla which has undergone various reductions in the length of certain digits. All species of Phyllomedusa, as far as is known, lay their eggs over water. They do not beat this egg mass into foam as in the case of Poly- pedates, but in some species the parents may fold the leaves together over the mass of eggs. The tad- poles which hatch have a broad back fin similar to Hyla versicolor. One spe- cies of the genus has been recorded to have its mouth produced into a funnel which apparently assists it in surface feeding. A sim- ilar umbrella mouth has.
