The under-side of the ¢ is bright yellow in the wet season 
(Fig. 13), sand-coloured in. the dry (Fig. 15). 
The under-side of the 2 is sand-coloured at all seasons. 
See pp. 157, 158 above. In all the figures, the under-side 
alone is represented. 
It should be borne in mind that in the absence of colour it 
is impossible to represent the tone-values with complete 
accuracy. The difference, e.q., between the clear yellow 
of Figs, 9, 13, and the sandy tint of Figs, 10, 14, is far 
more conspicuous in nature than in the Plate.
