YOYAGE UP THE TAPAJOS. 
Chap. II. 
dense, and broad sunny paths skirted by luxuriant beds 
of Lycopodiums, which form attractive sporting places 
for insects, extend from the village to a swampy hollow 
or ygapo, which lies about a mile inland. Of butter- 
flies alone I enumerated fully 300 species, captured or 
seen in the course of forty days within a half-hour's 
walk of the village. This is a greater number than 
is found in the whole of Europe. The only monkey I 
observed was the Callithrix moloch — one of the kinds 
called by the Indians Whaiapu-sai. It is a moderately- 
sized species, clothed with long brown hair, and hav-

to the Cebi it has none of their restless vivacity, but 
is a dull, listless animal. It goes in small flocks of five 
or six individuals, running along the main boughs of 
the trees. One of the specimens which I obtained 
here was caught on a low fruit-tree at the back of our 
house at sunrise one morning. This was the only 
instance of a monkey being captured in such a position 
that I ever heard of. As the tree was isolated it must 
have descended to the ground from the neighbouring 
forest and walked some distance to get at it. The 
species is sometimes kept in a tame state by the 
natives : it does not make a very amusing pet, and 
survives captivity only a short time. 
I heard that the white Cebus, the Caiarara branca, a 
kind of monkey I had not yet seen, and wished very 
much to obtain, inhabited the forests on the opposite 
side of the river ; so one day on an opportunity being 
afforded by our host going over in a large boat, I 
crossed to go in search of it. We were about twenty per-
