reJdish-bro^vn of the liindcr part of tlio body. Occasionally the white band below 

 the eye assumes a brownish colour, and the animal apjx^ars to have a brown band 

 down each side. He does not always, however, appear in this gay dress. While 

 I am writing I see him coming down the trunk of one of the trees in a vciy faded 

 garment. His skin suggests a bright calico, after it has been washed, whose colours 

 succumb to soap. Tlie blue is there, but it is no longer the liright blue of yesterday. 

 It has changed to a dull light indigo colour. He runs across the grass to the foot of 

 another tree and stops on the bare gi'ound at its base, where for a minute or more he 

 bites with great energy at a struggling grasshopper (?), and while thus exercising 

 himself the blue fades out from his body altogether and his whole body takes the 

 colour of the brown earth on which he stands. After tarrying a minute or two he 

 ran up the other tree and the dull light blue colour seemed to return to liim as he ran 

 up the tree."
