3:15 pm. Just after rain stops. Forest still quite wet. Find what is probable, same group of tamarins a few hundred yards away. Running and leaping horizontally 20-50 ft up. Silent. Moderately cohesive. 

(This horizontality probable due to fact that vertical trunks and branches tend to be disperse here.)

ADDITION: The forest here certainly is not swamp forest. But it is the nearest thing to it. 

NOTES: I have had some chance to talk to the local indians [[Indians]] here. They say some rather peculiar things. Only monkeys nearby are "chichico negro", the tamarin, "chichico blanco", presumably Saimiri, and "tarique", presumably Cebus Albifrons. They say that the chichico blancos and tariques tend to associate with one another!!! If so, it would appear that the albifrons here have the same habitat preferences and social habits as apella elsewhere. 

All or most of the (other) larg(er) monkeys are supposed to be far away, presumably in higher forest. 

Possible exceptions are titis. The locals know both moloch and torquatus. Give good descriptions of them. Both called "suga." According to our guide today, both species occur in same forests. (He says forests like the one we traversed today. But he may not distinguish between poorly and well drained soil. Both species occur in family groups of 2-5 vids. But supposedly never 

Transcription Notes:
Humboldt's white-fronted capuchin (Cebus albifrons) is a species of gracile capuchin monkey. The titis, or titi monkeys, are the New World monkeys of the subfamily Callicebinae.
