+525+. Thus, for example, the contrast between the social system of sterile Central Australia and that of certain tribes on the comparatively fertile southeast coast is marked; the Kurnai have practically no clan totemism. In the islands of Torres Straits and in New Guinea agriculture marks a dividing line between stricter and looser organizations based on regard for the totem. The agricultural Melanesian and Polynesian tribes, with great regard for animal patrons, lay stress on the family or on voluntary associations rather than on the clan. In Africa the partially civilized peoples, such as the Baganda and adjacent tribes in the east, and Yoruba, Dahomi, and Ashanti in the west, have fairly well-developed religious organizations, in which totems play a subordinate part. The customs of certain tribes in the south are especially worthy of note: the pastoral Herrero have a double system of clans, maternal and paternal, and their food restrictions are curiously minute, relating to parts of animals or to their color; the Bakuana, who are pastoral and agricultural, kill the clan eponymous animals, though unwillingly, and appear not to regard them as ancestors. The non-Aryan tribes of India have been so long in contact with Aryan civilization that in many cases, as it seems, their original customs have been obscured, but at present among such agricultural tribes as the Hos, the Santhals, and the Khonds of Bengal, and some others, totemic organizations are not prominent, and the Todas, with their buffalo-cult, show no signs of totemism.
