 well-marked pure black stripe, broadest on the middle part and narrowing off both 

 anteriorly and posteriorly. Tail at base like the lower back, though becoming darker 

 towards the tip wlien seen from above. The individual hairs on the tail with one 

 or two buffy bands giving a grizzled appearance. Underparts of the body påle 

 orange yellow especially on the throat. Sides of lower parts grcvish.
