at midsummer, we have taken it in abandoned ant-hills near a vlei far 
remote from bush, but in general it seems to favour bush or forest 
districts, and is said to climb trees. Andrew Smith took his specimens 
in burrows in the ground.

The Kimberley specimens no doubt came in firewood from Bechuana- 
land : Smith's observation on the occurrence of this species within the 
internal cavities of trees furnishes the explanation.

This species is not common at Kimberley. One specimen was found 
impaled through the head on a thorn-bush, evidently the victim of 
a shrike.

This tiny frog is extremely variable in its colours, which range from 
vivid greens to browns and reds ; there may or may not be a yellow ver- 
tebral line and a similar one dorsolaterally, but blotches and spots of 
varying size are nearly always present though they may not be very 
definitely arranged. The various colours are all to be found in the same 
colony, and in captive specimens our experiments failed to bring any 
colour response by changing the colours of the environment. It is a 
terrestrial species of diurnal habits, and takes to water only at breeding- 
times, when it may be found in great numbers amongst the weeds or 
under the stones at the edge of shallow pools. During the dry season it 
remains hidden under stones in damp places or in the cracks of muddy 
ground. It can climb with ease over smooth vertical surfaces, such as a 
pane of glass, the belly being closely pressed against that surface. The 
breeding call is very characteristic, and resembles the sound made by the
