not seen an example from this island, but P. neme@us is a native of 
Cochin China, and the Island of Hainan, and neither it, nor its relative, 
P. NIGRIPES, has ever been found, so far as I am aware, in Borneo or 
on any of the near lying islands. A long-nosed monkey colored like 
either of the two species mentioned, would certainly represent an 
undescribed species. 
Mr. Hornaday met with the Proboscis Monkey in Borneo, and 
states, “as usual, they were over water, and being swift climbers and 
quite shy were hard to kill. I saw altogether during my ramblings 
in the forests of Borneo, perhaps a hundred and fifty Proboscis 
Monkeys, and without a single exception, all were over water, either 
river, lake, or submerged forest. As long as they are in sight they 
are very conspicuous objects, choosing the most commanding positions 
in open tree-tops; once I saw thirteen in one tree, sitting lazily on the 
branches, as is their habit, sunning themselves and enjoying the 
scenery. It was the finest sight I ever saw in which Monkeys played a 
part. The cry of the Blanda is peculiar and unmistakable. Written 
phonetically it would be ‘Honk’ and occasionally ‘Kee-Honk’ long 
drawn and deeply resonant, quite like the tone of a bass viol. The 
Proboscis Monkey is a large animal of striking appearance both in 
form and color. Taken altogether, Nasalis larvatus is to the hunter- 
naturalist a very striking object of pursuit, and were he not partially 
eclipsed by the orang he would be the most famous Quadrumane in 
the East Indies.” 
There is a more or less general impression that monkeys cannot 
swim, and the following account of a Proboscis Monkey swimming 
one of the rivers in Borneo was given to me by my friend Mr. C. 
William Beebe, the Curator of Birds in the New York Zoological 
Garden, and proves at all events as regards this species, that such a 
belief is entirely incorrect. The natives informed Mr. Beebe that 
these monkeys were often seen swimming across the rivers. 
“Up the Rejang River in small steamer. At 7 A. M. (about three 
and a half hours below Sibu) where the river was about one hundred 
and fifty yards wide we passed a Long-nosed Monkey (Nasalis lar- 
vatus) in mid-stream swimming strongly. His fore arms moved dog- 
fashion downward and back, but he swam first on one side then on 
the other. Once when he turned his head with its prominent nose, 
backward to look at us, his arms swept far apart, man-fashion, but 
almost at once he returned to the other method. These monkeys 
inhabit all this delta region of half submerged nipa palms and owing 
to the wide intersecting tidal reaches, they must frequently utilize
