"A certain mysterious connection exists between a family and its KOBONG, so that a member of a family will never kill an animal of the species, to which his KOBONG belongs, should he find it asleep; indeed, he always kills it reluctantly, and never without affording it a chance to escape. This arises from the family belief, that some one individual of the species is their nearest friend, to kill whom would be a great crime, and to be carefully avoided. Similarly, a native who has a vegetable for his KOBONG, may not gather it under certain circumstances, and at a particular period of the year." From the foregoing quotation, it is apparent that very little difference exists in the custom as practised in Western and Southern Australia. In the former, however, there appears to be an unwillingness to destroy the object represented by the kobong or tiende that I have never observed in the latter. But very little appears to be known on this subject at present, as far as regards the reason for assuming the tiende, or its connection with the individual or family it may represent. The same tiende seems to descend from a father to his children; but I have been told occasionally of instances where such has not been the case. There are several striking differences between the customs and habits of the Aborigines of Western Australia, narrated by Captain Grey, and those in force among the tribes I have myself been best acquainted with in Southern or South-eastern Australia. One singular peculiarity is described by Captain Grey. "One of the most remarkable facts connected with the natives, is that they are divided into certain great families, all the members of which bear the same names, as a family or second name: the principal branches of these families, so far as I have been able to ascertain, are the Ballaroke Tdondarup Ngotak Nagarnook Nogonyuk Mongalung Narrangur. "But in different districts the members of these families give a local name to the one to which they belong, which is understood in that district, to indicate some particular branch of the principal family. The most common local names are, Didaroke Gwerrinjoke Maleoke Waddaroke Djekoke Kotejumeno Namyungo Yungaree. "These family names are common over a great portion of the continent; for instance, on the Western coast, in a tract of country extending between four and five hundred miles in latitude, members of all these families are found. In South Australia, I met a man who said that he belonged to one of them, and Captain Flinders mentions Yungaree, as the name of a native in the Gulf of Carpentaria. "These family names are perpetuated, and spread through the country, by the operation of two remarkable laws:-- "1st. That children of either sex, always take the family name of their mother. "2nd. That a man cannot marry a woman of his own family name."
