brown. A fuliginous band may be seen extending from the supracili- 

 ary region along the upper portion of the flanks to a certain distance 

 on the tail, where it tapers into a point ; over the eye and along the 

 canthus rostralis, it is reduced to a whitish fillet. Immediately beneath 

 that band is a blackish streak, which may be traced from the nostril 

 across the eye, over the auricular aperture, to the origin of the tail, 

 broadest along the middle of the flanks. From the axilla to the groin, is 

 a yellowish line margining the dark streak just alluded to. The lower 

 portion of the sides is yellow or yellowish-brown, speckled with black ; 

 the speckles extending beyond the middle of the length of the tail, as 

 a continuation of the dark streak of the sides. The legs are brown, 

 with darker spots interspersed. The lips are yellowish, the throat 

 whitish, obscurely lineolated on the sides, whilst the abdomen is dull 

 yellow or brownish, unicolor.
