inside of thighs strongly reddish brown; tail yellowish brown, darker 

 apically, the hairs individually being blackish brown for most of their 

 length and broadly tipped with yellowish gray. 



Another old male from El Llagual (March 12) has the pelage con- 

 siderably worn, and perhaps for this reason presents only a tendency 

 to lateral crests more so on one side than on the other which 

 apparently had been either shed or worn away. The general colora- 

 tion of the dorsal surface, tail, and outside of limbs is very similar to 

 that of the Maripa specimen, but the light tips of the hairs are paler, 

 more yellowish, and less rufous. The ventral surface, however, is 

 quite different, the remaining hairs of the breast and abdomen (which 

 are nearly naked) being brown with a slight reddish cast, while the 

 shoulders and upper arms are pale buff instead of rusty yellow. 



An old female from La Union (Oct. 9) is in good pelage but lacks the 

 lateral crests. The crown and middorsal region from nape to tail 

 are brownish black with a slight rufescent tinge, the hairs very slightly 

 tipped with dull rusty yellow. The under surface is about as in the 

 La Union specimen, with the buffy tints several shades stronger. 



An old female from Maripa (April 21) is in very worn pelage and 

 evidently much faded, the light color on the sides of the face and chin 

 being soiled grayish white and on the shoulders and upper arms very 

 pale buffy white. The dark color on the top of the head forms a 

 wedge-shaped median band, beginning as a mere line ajid widening 

 gradually as far back as the ears where it occupies about two thirds 

 of the interaural space.
