BREEDING BIOLOGY OF LITORIA-BOOROOLONGENSIS (MOORE, 1961), AND LITORIA-LESUEURI (DUMERIL-AND-BIBRON, 1841) (ANURA, HYLIDAE) AND COMMENTS ONPOPULATION DECLINES OF LITORIA-BOOROOLONGENSIS

The embryonic and larval development of Litoria booroolongensis are de scribed and compared to those of the closely related Litoria lesueuri. The habitat, behaviour and distribution of each species are compared and indications of marked population declines of L. booroolongensis ar e discussed. The two species have similar lotic life-histories but som e differences occur in body proportions, colour in life, behaviour and habitat. In both species the egg mass is a compact gelatinous clump, typical of frogs breeding in a lotic environment. The tadpoles of both species are adapted to the lotic environment and have streamlined bod ies and suctorial mouth-parts. Adult L. booroolongensis aggregate thro ughout the year and are active diurnally in summer.
