the lowland form is quite, or nearly, uniformly reddish or orangeous, 
as in splendidus, the next higher form by the acquisition or increase of 
the black pigment becomes contrastingly colored. Finally, the low- 
land agouti forms (norosiensis) become darker agouti at the next 
higher levels. From these levels where the darker forms occur to the 
highest forested zones the length and thickness of the pelage increases. 
The reddish subterminal band of the hair becomes narrower and fre- 
quently paler or even yellowish, while the longer gray basal portions 
of the hairs tend to show through at the surface. This results in a 
paler, uniformly agouti, or olivaceous appearing animal. The under- 
parts follow the same tendencies (except in the Sierra Nevada de 
Santa Marta). From the lowlands to the next altitudinally higher 
levels, reddish underparts are generally followed by deeper red under- 
parts, white underparts by red, or mixed red and white underparts. 
_At the highest levels, the red may persist, it may become yellow, or 
mixed red or yellow with white.
