The Phryniscidæ, or Toads with imperfect ears and tongue fixed in front, are widely distributed over the warmer regions of the earth, but are most abundant in the Neotropical region and Australia, while only single species occur in the Old World. The genera are:—
Phryniscus (7 sp.), from Costa Rica to Chili and Monte Video; Brachycephalus (1 sp.), Brazil; Pseudophryne (3 sp.), Australia and Tasmania; Hemisus (1 sp.), Tropical Africa; Micrhyla (1 sp.), Java.
