 by Dr. W. L. Abbott. 



Distribution. — As far as known only the type locality. 



Characters. — Comparison of this form with any others of the 

 specifis is vmnecessary as the color and pattern are quite distinctive. 



Color. — General color of the upper parts rich russet brown (close 

 to mars brown of Ridgway), palest on the limbs, strongest on the 

 shoulders. Dorsal line rich vandyke brown, tending toward seal 

 brown, the stripe brown on the shoulder, decreasing in width and 

 intensity posteriorly, becoming almost obsolete on the rump ; general 

 tint on each side of the dorsal line is overcast with a silvery 

 " bloom," which is caused by the tips of the hairs being of that 

 tint." Crown patch broad, rich burnt umber, extending from ear 

 to ear, but not involving them, anteriorly sending a broad bar to 

 the upper margin of the customary black ocular rings; cheeks 

 suffused with dusky brown. Anterior limbs with the extremities 

 much lighter in color than the remainder of the limbs. Lower 

 surface pale cinnamon, throat silvery white. 



Specimens examined. — One, the type. 



* ' The hair on all the dorsal surface is more or less tipped with silvery, 

 but this character is much more apparent in the portion mentioned 

 above. The presence of the silvery suffusion near the dorsal line is 

 shared hj javanicus, but in that form distinct longitudinal bars are formed.
