The study of evolution in the ontogeny of the Frogs (Order Salientia or Anura) has been rather neglected. They have probably been dismissed as one of the minor orders of the vertebrate phylum, characterized by a well-known life cycle, which comprises an aquatic larval period and metamorphosis into terrestrial tetrapods. The tropical and subtropical frogs show many deviations from this mode of development. At the present time, the life histories of less than one-third of the described species of frogs are known (Orton, 1946). It seems probable that as the opening up of this field proceeds other unusual life histories will be added to those already described in the much scattered literature. The very facts that the Amphibia are the most complex vertebrates in which larvae occur, that those of the Salientia are not always aquatic and are sometimes replaced by direct development, ought to make the order interesting from the point of view of ontogenetic evolution. The present preliminary survey is based on a number of peculiar modes of anuran development observed in southeastern Brazil, in the course of many years, by the late Professor Adolpho Lutz, the author, and their assistant Mr. Joaquim Venancio, and recorded either for the first time (Lutz, 1928, 1929, 1931; B. Lutz, 1944; Lynn and B. Lutz, 1946, 1947), or in confirmation of earlier work. Parallel or convergent cases from other regions may be mentioned but the data available do not permit detailed comparison. (For factual literature see Brandes and Schoenichen, 1901; Noble, 1925, 1927, 1931; B. Lutz, 1947). GENERAL TREND
