dc.description.abstract "The chromosome complements of five species of hylid frogs are described and illustrated. One of the species, Smilisca baudini, is a 'generalized' hylid and is used for comparative purposes. The other four species, Pternohyla fodiens, Triprion petasatus, Hyla septentrionalis, and Hyla brunnea, are among those having cephalic adaptations that are referred to as the casque-headed hylids. Three of these (P. fodiens, T. petasatus, and H. septentrionalis) have karyotypes that are indistinguishable from that of the generalized S. baudini: This includes a diploid number of 24 bi-armed chromosomes (12 pairs), of which six are relatively large and six relatively small. The karyotype of the other casque-headed species is vastly different, however: Hyla brunnea has a diploid number of 34 chromosomes, of which 20 are uni-armed. Following a review of the chromosome variation known to occur within the Hylidae, it is inferred that the karyotype of H. brunnea was derived from an ancestral karyotype similar to that of H. septentrionalis by means of at least five whole-arm chromosomal aberrations"--P. 3. en_US
