Alcohol-preserved specimens (n = 340) were examined. Seventeen measurements were taken and are compared between the sexes. The distribution and habitat for each species are discussed. The current status of the amphibians of Jordan is discussed. > Kurzfassung Eine Schwanzlurch-Art (Ommatotriton vittatus) und vier Froschlurch-Arten (Pseudepidalea viridis, Pelophylax bedriagae, Hyla savignyi und Pelobates syriacus) wurden nachgewiesen für Jordanien. Alkoholfi xierte Exemplare (n = 340) wurden untersucht. Siebzehn morphometrische Maße wurden erhoben und geschlechtsabhängig verglichen. Die Verbreitung und das Habitat für jede Art werden diskutiert. Der gegenwärtige Status der Amphibien in Jordanien wird diskutiert. > Key words Amphibians, Jordan, ecology, morphometrics.
