Colour.— Back and upper portion of sides intermediate between yellowish 

 brown and umber-brown, the colour of the sides being separated from that of 

 the back by a narrow cream-yellow band, which commences near the hind 

 head and is lost before it reaches the tail. Below the brown of the side, 

 which exhibits the appearance of a longitudinal stripe, there is a second 

 cream-coloured band about the width of the first, but neither so distinctly 

 denned nor so lengthened, rarely reaching to the middle of the body. Behind, 

 where this second line does not exist, the lower edge of the brown gradually 

 fades into a light-brownish purple-red. Lower portion of sides and under 

 parts straw-yellow. Besides the yellow bands already mentioned there is 

 one of a brighter tint edging the lateral and anterior parts of the upper sur- 

 face of the head, and another extending between the outer corner of the eye 

 and the angle of the mouth ; there are also some more or less vertical 

 lines of the same colour on the upper lip. 



Young. 



The ground colour sienna-yellow glossed with purplish red, and the back 

 and the sides towards the head are freely variegated with several rows of spots 

 of a brownish red colour. Line edging the upper surface of the head, and 

 one between the eye and the angle of the mouth bright yellow, the former is 

 connected with its fellow of the opposite side by a narrow transverse vellow 

 line ; upper and under lips pale yellow vertically barred with brown. Under 

 parts pale straw-yellow.
