Sir John Lubbock, _Origin of Civilization_ (New York, 1889), maintains the theory and introduces the name of "communal marriage." McLennan is in the main supported by Robertson Smith, _Kinship and Marriage in Early Arabia_ (Cambridge, 1885). This book may be read in connection with Wilken, _Das Matriarchat bei den alten Arabern_ (Leipzig, 1884); Kohler, "Vorislamitisches Recht der Araber," in _ZVR._, VIII; Friedrichs, "Das Eherecht des Islams," _ibid._, VII; Vincenti, _Die Ehe im Islam_ (Vienna, 1876); Pischon, _Der Einfluss des Islams auf das häusliche, soziale, und politische Leben seiner Bekenner_ (Leipzig, 1881); Perron, _Femme arabe_ (Paris and Alger, 1858); Kremer, _Kulturgeschichte des Orients unter den Kalifen_ (Vienna, 1875); Vámbéry, _Der Islam im neunzehnten Jahrhundert_ (Leipzig, 1875); his _Türkenvolk_ (Leipzig, 1885); Hanoteau and Letourneux, _La kabylie et les coutumes kabyles_ (Paris, 1893); and Baway, "The Marriage Customs of the Moors of Ceylon," in _Journal of the Royal Asiatic Society_, Ceylon Branch, 1887-88, X, 219-33 (Colombo, 1888). Read also Redhouse, _Notes on Tylor's 'Arabian Matriarchate,'_ propounded by Tylor before the British Association, Montreal, 1884. For the matrimonial institutions of the Australian aborigines, whose so-called "group-marriage" has played so great a part in speculation, see especially Fison and Howitt, _Kamilaroi and Kurnai_ (Melbourne, 1880), supplemented by their "Deme and the Horde," in _Journal of the Anth. Inst._, XIV, 142-68 (London, 1885), comparing Attic and Australian classes and local divisions; Fison's article on "Primitive Marriage," in _Pop. Sci. Monthly_, XVII (New York, 1880); his paper on "Classificatory Systems of Relationship," in _Brit. Assoc. Adv. Sci._ (Oxford, 1894); Howitt's "Remarks on the Class Systems Collected by Mr. Palmer," in _Journal of the Anth. Inst._, XIII, 335-46 (London, 1884); his "Dieri and Other Kindred Tribes of Central Australia," _ibid._, XX; "Further Notes on the Australian Class Systems," _ibid._, XVIII, 31-36 (London, 1889); "Organization of Australian Tribes," in _Trans. Roy. Soc. of Victoria_, I, Part II (1889); and his "Australian Group Relations," in _Rep. Smith. Inst._, 1883 (Washington, 1885). Important also are Cunow, _Die Verwandtschafts-Organisationen der Australneger_ (Stuttgart, 1894), supplementing Morgan's _Ancient Society_, while rejecting some of Morgan's and Fison's conclusions; Kohler, "Das Recht der Australneger," in _ZVR._, VII; his later _Zur Urgeschichte der Ehe_ below named; McLennan, _Studies_, II, 278-310; Curr, _The Australian Race_ (Melbourne, 1886), rejecting the theory of "group-marriage" and promiscuity; especially Roth's _North-West-Central Queensland Aborigines_
