— hydromedusa, (Kuhl) Tschudi, Batr. p. 80. 
Vomerine teeth in two oblique series extending much beyond the 
level of the hinder edge of the choanee. Head moderate ; snout 
rounded ; tympanum distinct, half the size of the eye; interorbital 
space as broad as the upper eyelid. Fingers moderate, first ex- 
tending beyond second ; toes broadly webbed, with slightly swollen 
tips; subarticular tubercles of fingers aud toes well developed; an 
oblong inner metatarsal tubercle. The hind limb being carried 
forwards along the body, the tibio-tarsal articulation reaches the 
eye. Skin smooth; upper eyelid tubercular; a fold from the pos- 
terior angle of the eye to the shoulder. Brown above, with a few 
reddish spots ; hinder side of thighs marbled with dark brown.

Ixalus aurifasciatus, Peters, Mon. Berl. Ac. 1868, p. 455. 
Vomerine teeth in two strong oblique series commencing from the 
inner anterior angle of the choanz; lower jaw with two fang-like 
bony prominences in front, sometimes scarcely developed. Head 
large; snout rather pointed; occiput more or less swollen on the 
sides; interorbital space generally one half broader than the upper 
eyelid ; tympanum distinct, variable in size, generally much smaller 
than the eye. Fingers moderate, first much longer than the second ; 
toes broadly webbed, with distinctly swollen tips; subarticular tu- 
bercles of fingers and toes well developed ; inner metatarsal tubercle 
elongate, blunt; no outer tubercle. The hind limb being carried 
forwards along the body, the tibio-tarsal articulation reaches the eye 
or a little beyond. Skin smooth above, or with small rounded warts ; 
upper eyelid tubercular ; a strong fold above the tympanum. Brown 
or blackish above ; sometimes a light dorsal stripe’ Male without 
vocal sacs. 
Young specimens have a very different appearance from that of 
the adult, having a narrow glandular fold on each side of the back, 
and the interorbital space not broader than the upper eyelid. 
Gradually the glandular fold disappears and the interorbital space 
becomes broader.
