We spent only one day at San Fernando de Atabapo, despite the village, with its pirijao palms and their peach-like fruit, promising us a delightful refuge. Tame pauxis (Crax alector) ran round the Indian huts; in one of which we saw a very rare monkey that lives on the banks of the Guaviare. It is called the caparro, which I have made known in my Observations on Zoology and Comparative Anatomy. Its hair is grey and extremely soft to touch. It has a round head, and a sweet, agreeable expression.
