 commences just behind the ventral; the second dorsal slightly 

 larger than the first, and has the anal beneath its anterior one 

 half or two thirds. Colour of a tawny brown, becoming lighter 

 beneath. Lines of spots, some of which occasionally become con- 

 fluent, exist along the body; there may also be bands or ocelli.
