All specimens were found in rain water pools on the hillside above the vil- lage at about 70 m elevation. The nomenclature for this frog is unsettled. Zhao and Adler (1993: 74) notwithstanding, the sole consis- tent character given by Liem (1970) separating "Polypedates" from Rhacophorus is the diplasio- coelous vertebra of the former. One of us (JL) finds this character prone to individual variation in adult frogs and questions whether any genus founded on such a single character could be monophyletic. Zhao and Adler (1993: 156) accepted the notion of Matsui et al. (1986) that Chinese specimens should be called megacephalus (type locality Hong Kong: Hallowell. 1861) "based on comparisons of Taiwanese and Bornean ; Taiwan and Borneo are both continental shelf islands. Borneo is more than twice as far from Wai Ling Ding (and Hong Kong) as is Tai- wan, but we see no rationale for assigning populations on that basis, and opine that this species, abundant at Hong Kong (Karsen et al., 1986: 31), should be judged on evaluation of topotypic material. Nor do we believe the minor differences noted by Matsui et al. (1986) necessarily imply species-level distinction. Karyotypes often vary within species ( Schmid et al., 1994). A demonstration of sympatry would be convincing. In addition to the New Territ
