es to its sleeping holes for mid-day siesta as well as night sleep!!! (There are a few small, drilled holes in same tree trunk. Antuco says that these are not feeding holes of marmosets. Tree is called "Amarillo". Antuco says that the marmosets do not feed on this species.)

Then walk through plantation. Antuco points out banana and chirimoya where local people claim to have seen Callimico. He himself says that he saw 2 Callimico near a fig tree ca 200 yds away. (This is low land. Quite flat. But provably several feet or yards higher than most of the land of the island in the Rio Guineo.)

Come back from our walk ca 4:30 pm. Find that capture young has escaped from its box is tugging at its leash on the ground. Uttering WLW's. Jon picks its up and holds it in his hand. Continues uttering WLW's and tries to escape semi-continuously. Utters Rattles when and if it does manage to escape temporarily.

While in the hand, it occasionally interrupts WLW's to utter 1 or 2 Rasps. These Rasps definitely, seem to be infantile!!! And at least 2 of the Rasps are followed immediately by High Trills! This is very reminiscent of some infantile Rasp - Infantile squeak series of Saguinus geoffroyi. Followed by more WLW's.

Inconceivable that the vocal repertory of Callimico is almost perfectly intermediate between that of Callicebus and that of Saguinus!!!
