Metamorphling specimens of the endangered frog Litoria aurea were sampled from two relatively unpolluted sites in the metropolitan Sydney area for baseline information on sex ratio, vertebral number, vertebral and sacral diapophysis asymmetry and phalangeal formula. The sex ratio was not significantly different from parity. Vertebral number was a constant eight which is typical for the family Hylidae. There was a vertebral diapophysis asymmetry in one specimen from one population (frequency: 2.4%). The only phalangeal abnormality detected was the late ossification of the terminal phalange in the digits 2-4 of the right manus of one specimen in the other population (frequency: 2.8%).
