brown; light on the belly. The bach and sides ornamented 
sometimes with longitudinal waved stripes of a light tinge, edged

covered with narrow longitudinal lines as usually described, but 
the third was blotched all over with white on a very dark 
ground, not unlike some individuals of Coitus bubalis.
