I cannot resist giving another scene which was witnessed by this same naturalist; an eagle seized a young Cercopithecus, which, by clinging to a branch, was not at once carried off; it cried loudly for assistance, upon which the other members of the troop, with much uproar, rushed to the rescue, surrounded the eagle, and pulled out so many feathers, that he no longer thought of his prey, but only how to escape.
Dutch, retention of their colour by the, in South Africa. Duty, sense of. Duvaucel, female Hylobates washing her young. Dyaks, pride of, in mere homicide. Dynastes, large size of males of. Dynastini, stridulation of. Dytiscus, dimorphism of females of; grooved elytra of the female. Eagle, young Cercopithecus rescued from, by the troop. Eagle, white-headed, breeding in immature plumage.
I was so much surprised at his account, that I took a stuffed and coiled-up snake into the monkey-house at the Zoological Gardens, and the excitement thus caused was one of the most curious spectacles which I ever beheld. Three species of Cercopithecus were the most alarmed; they dashed about their cages, and uttered sharp signal cries of danger, which were understood by the other monkeys.
In the Cercopithecus cynosurus and griseo-viridis one part of the body, which is confined to the male sex, is of the most brilliant blue or green, and contrasts strikingly with the naked skin on the hinder part of the body, which is vivid red.
Bartlett, A.D., period of hatching of bird's eggs; on the tragopan; on the development of the spurs in Crossoptilon auritum; on the fighting of the males of Plectopterus gambensis; on the Knot; on display in male birds; on the display of plumage by the male Polyplectron; on Crossoptilon auritum and Phasianus Wallichii; on the habits of Lophophorus; on the colour of the mouth in Buceros bicornis; on the incubation of the cassowary; on the Cape Buffalo; on the use of the horns of antelopes; on the fighting of male wart-hogs; on Ammotragus tragelaphus; on the colours of Cercopithecus cephus; on the colours of the faces of monkeys; on the naked surfaces of monkeys.
Now, if one thousand years may represent the period required for the evolution of the species S. nasalis, and of the other species of the genus Semnopithecus; ten times that period should, I think, be allowed for the differentiation of that genus, the African Cercopithecus and the other genera of the family Simiidæ the differences between the genera being certainly more than tenfold greater than those between the species of the same genus.
In the paper to which I have referred, Professor Bischoff does not deny the second part of this statement, but he first makes the irrelevant remark that it is not wonderful if the brains of an orang and a Lemur are very different; and secondly, goes on to assert that, "If we successively compare the brain of a man with that of an orang; the brain of this with that of a chimpanzee; of this with that of a gorilla, and so on of a Hylobates, Semnopithecus, Cynocephalus, Cercopithecus, Macacus, Cebus, Callithrix, Lemur, Stenops, Hapale, we shall not meet with a greater, or even as great a, break in the degree of development of the convolutions, as we find between the brain of a man and that of an orang or chimpanzee."

"Javan Loris" "Proceedings of the Zoological Society" 1862. These are: Semnopithecus. Cercopithecus. Macacus. Otolicnus. Stenops. Lemur. In July 1861 Mr.
The next day, each wished to be satisfied; a regular hunt was organized against this phenomenon; they set out, invaded his retreat, pursued him, surrounded him, at last seized him, and the brave sailors of Great Britain discovered with stupefaction, in this monopedous, acephalous man, in this satyr, this cercopithecus, what? A countryman, a Scotchman, a subject of Queen Anne!
And if, instead of putting Hapale out of its natural place, as Professor Bischoff most unaccountably does, we write the series of animals he has chosen to mention as follows: Homo, Pithecus, Troglodytes, Hylobates, Semnopithecus, Cynocephalus, Cercopithecus, Macacus, Cebus, Callithrix, Hapale, Lemur, Stenops, I venture to reaffirm that the great break in this series lies between Hapale and Lemur, and that this break is considerably greater than that between any other two terms of that series.
