Identification of Rana hymenopus Boulenger, 1920

I examined the type NHMUK 1947.2.28.65, and compared the description with representative specimens of the Maluti River Frog AACRG 1105 and the Phofung River Frog AACRG 0 648, and other material listed in the appendix. Four statements confirm that the description refers to the Phofung River Frog, while the rest of the description is not diagnostic—Snout rounded, scarcely projecting, a little longer than the eye; interorbital width three-fourths that of the upper eyelid; three phalanges of fourth toe free of web (toes half webbed); two phalanges of third and fifth toes free of web. The type ( Fig. 2 ) is in good condition, and can confidently be recognised as a Phofung River Frog.
