B. DARWINII. Chili, 1849. This is, perhaps, the best known and most ornamental of the family. It forms a dense bush, sometimes 10 feet high, with dark glossy leaves, and dense racemes of orange-yellow flowers, produced in April and May, and often again in the autumn. B. EMPETRIFOLIA. Straits of Magellan, 1827.
Owen, nearest to the Cape Anteater, but in some other respects it approaches to the armadilloes. Fourthly, the Mylodon Darwinii, a closely related genus of little inferior size. Fifthly, another gigantic edental quadruped. Sixthly, a large animal, with an osseous coat in compartments, very like that of an armadillo. Seventhly, an extinct kind of horse, to which I shall have again to refer.
The shells out of the layers of brown limestone, included in the black calcareous shale-rock, which latter, as just stated, replaces the white siliceous sandstone, consist of: Pecten Dufreynoyi, d'Orbigny, "Voyage" Part Pal. Turritella Andii, d'Orbigny, "Voyage" Part Pal. Astarte Darwinii, E. Forbes. Gryphaea Darwinii, E. Forbes. An intermediate form between G. gigantea and G. incurva.
Krause, on a convoluted body at the extremity of the tail in a Macacus and a cat. Kupffer, Prof., on the affinity of the Ascidia to the Vertebrata. Labidocera Darwinii, prehensile organs of the male. Labrus, splendid colours of the species of. Labrus mixtus, sexual differences in. Labrus pavo. Lacertilia, sexual differences of. Lafresnaye, M. de, on birds of paradise.
In the southern part of Patagonia another species, much smaller, exists, the Avestris petise, now called Struthio Darwinii, in compliment to the naturalist who has described it. He states that not more than fifteen eggs are found in the nest of the petise, deposited by two or more females. This bird does not expand its wings when first starting at full speed, after the manner of the northern kind.
Described from my specimens and notes by the Reverend J.M. Berkeley in the "Linnean Transactions" volume 19 page 37, under the name of Cyttaria Darwinii: the Chilean species is the C. Berteroii. Hooker informs me that just lately a third species has been discovered on a third species of beech in Van Dieman's Land.
It must have been as large as a rhinoceros: in the structure of its head it comes, according to Mr. Owen, nearest to the Cape Ant-eater, but in some other respects it approaches to the armadilloes. Fourthly, the Mylodon Darwinii, a closely related genus of little inferior size. Fifthly, another gigantic edental quadruped.
Wallace's claim to the origination of the idea of natural selection; on the former barbarism of civilised nations; on improvements in the arts among savages; on resemblances of the mental characters in different races of men; on the arts practised by savages; on the power of counting in primeval man; on the prehensile organs of the male Labidocera Darwinii; on Chloeon; on Smynthurus luteus; finding of new mates by jays; on strife for women among the North American Indians; on music; on the ornamental practices of savages; on the estimation of the beard among the Anglo-Saxons; on artificial deformation of the skull; on "communal marriages;" on exogamy; on the Veddahs; on polyandry.
Reversion, perhaps the cause of some bad dispositions. Rhagium, difference of colour in the sexes of a species of. Rhamphastos carinatus. Rhea Darwinii. Rhinoceros, nakedness of; horns of; horns of, used defensively; attacking white or grey horses. Rhynchaea, sexes and young of. Rhynchaea australis. Rhynchaea bengalensis. Rhynchaea capensis. Rhythm, perception of, by animals.
In conclusion I may observe, that the Struthio rhea inhabits the country of La Plata as far as a little south of the Rio Negro in lat. 41 degs., and that the Struthio Darwinii takes its place in Southern Patagonia; the part about the Rio Negro being neutral territory. M. A. d'Orbigny, when at the Rio Negro, made great exertions to procure this bird, but never had the good fortune to succeed.
