Oriolus vulneratus *, with dark black plumage and a large patch of deep crimson in the middle of the breast, also marked on the wings with the same colour. This, though a very interesting bird, was of course eclipsed by the Calyptomena.
Five Dusuns came to-day from Melangkap to see how we were getting on. They say that they have been cutting a path for us to return to the village by, for if the river is high we shall not be able to return by that route. They brought us some coconuts and coarse cucumbers, which were very acceptable, for which they took in exchange my empty soup-and other tins.

The Dusuns were much taken with my kerchiefs, having never seen such fine linen ; they were also much interested with my watch, and listened to the compass, which they found was " not alive."
During the few hours of sunshine I was able to secure a few butterflies. Amongst them were four new species of Papilios, one very handsome speciesaP. stratiotesabeing creamy white, and marked with two bright crimson spots just above the base of the tail (opposite page, figs. 1 e 2). But by far the most interesting species was a white-and-black butterfly, Appias wliiteheadi (opposite page, figs. 5 e 6). This insect has the wings bordered with a broad margin of black. Its habits are, however, most peculiar : it flies up and down stream in small parties of from six to as many as twelve or fourteen individuals, each butterfly keeping exactly the same distance apartaabout two feet. The procession plays a perfect game of " follow my leader." The first butterfly's flight follows closely the rocks, and it rises and falls to each obstacle met with ; these movements are exactly imitated by the butterflies in the rear. The train is augmented by any stragglers,
