by subsidence would, by putting a stop to immigration and intercrossing of individuals from the mother-country, have allowed full scope to the causes which have led to the modification of the species while the continued stream of immigrants from Java would, by continual intercrossing, check such modification. This view will not, Marc jacobs outlet however, explain all the facts for the character of tiffany outlet the fauna of tiffany and co the Timorese group is indicated as well by the forms which are absent from it as by those which it contains, and is by this kind of evidence shown to be much more Australian than Indian.
No less than twenty-nine genera, all more or less abundant in Java, and most of which range over a wide area, are altogether absent while of the equally diffused Australian genera only about fourteen are wanting. This would clearly indicate that there has been, till recently, a wide separation from Java and the fact that the islands of Bali and Lombock are small, and tiffany outlet are almost wholly volcanic, and contain a smaller number of modified forms than the other islands, would point them out as of comparatively recent origin. A wide arm of the sea probably occupied their place at the time when Timor was in the closest proximity to Australia and as the subterranean fires were slowly piling up the.now fertile islands of Bali and Lombock, the northern shores of Australia would be sinking beneath the ocean.
