VIII. Pink-eyed Dilute Brown Agouti, YBrdpA (Fig. 8). 



Eyes pink; ears, tail, and feet very lightly pigmented with brown. In both ventral and 

 dorsal hairs this form resembles a dull intense pink-eyed brown agouti, differing chiefly 

 in the comparative lack of bright yellow pigment and in the mealy, washed-out look. 

 The agouti pattern is very weak indeed.
