Rana musica Chang and Hsü, 1932: 137 (nec Rana musica Linnaeus, 1758 ) [Types formerly Biol. Lab. Sci. Soc. China 6085, presumed lost in WW II. Type-locality: a pond of Hountsingping (= Hungchun-ping), Mount Omei , Omeihsien , 1300 meters altitude, Sichuan, China.]

Rana daunchina Chang, 1933: 209 . Replacement name for Rana musica Chang and Hsü, 1932 .

Material examined. – China: Sichuan Province, Hongya Xian (FMNH 232892–893), Mt. Omei (AMNH A 49752 , 49794, MCZ A-25747), western Sichuan (FMNH 15177), no exactly locality (FMNH 18969–970, 18976, 18978–979, 18981, 18984–986, 18989–990, 19145–148, 19166).

Taxonomic notes. – Chang & Hsü (1932) described Rana musica from Sichuan ( China) and later Chang (1933) replaced the name for R. musica by R. daunchina . Chou (1999: 391, table 1) examined vocal sacs in this species as “indistinct”. Our examination showed distinct external vocal sacs as wrinkled skin on throat at the corner of lower jaw.
