297 AUSTRALIAN COWRIES: PART II. By Tom Iredale. (By Permission of the Trustees of the Australian Museum.) (Plates xxvii.-xxix.) Since the publication of the first part (Vol. viii., pp. 96-135, 1935), there has been continued progress with our information regarding Cowries, from intensive collection in Australia, and from the publication of a complete resume of the Cowries of the world gained from study of European Museum collections alone. This resume has appeared in the Proceedings of the Malacological Society of London (Vol. xxiii., pp. 119-231, 1938-39) under the title of "Prodrome of (sic) a Monograph on Living Cypraeidae", by Drs. F. A. & M. Schilder. Obviously there must appear many discrepancies in results achieved by these very different methods of approach, and attempt at reconciliation is here undertaken. The Drs. Schilder (husband and wife) have been working on dead Cowry shells for almost twenty years, and have examined about 60,000 specimens from 2,200 localities, about eighty (80) public and private collec- tions being searched, while the literature, extending to some 2,500 papers, has been catalogued. Such a mass of information is now made available to all workers, and nothing but praise must be given to the authors for this excellent research. This must be emphasized as otherwise my many criticisms may be misunderstood. The emendations now offered are mainly the result of local field ex- perience, and are all intended to be constructive, as the basis prepared by the Schilders is a very complete foundation. My own taxonomic knowledge enables the suggestion of some alterations, but the chief purpose of this part is the recording of new facts gained in the field. For most of these I am indebted to Messrs. H. Bernhard, A. A. Cameron, C. F. & J. Laseron, and H. S. Mort 'for local assistance; to my colleague, Mr. G. P. Whitley, for material from that difficult locality, Shark's Bay, Western Australia; to Mr. Melbourne Ward, the initiator of the earlier paper, who has been very energetic procuring a fine collection from Western Northern Territory; and to the Rev. and Mrs. W. Chaseling, who have made large and valuable collections about Yirrkala, Eastern Arnhem Land, Gulf of Carpentaria. These last two collections fill in the only lacunae on the coast of Australia, thereby paving the way for a List of the Marine Mollusca of Australia, a desideratum hitherto impossible of accomplishment. I am continuing these notes in the order of the previous paper, but the Schilders have utilised a somewhat different arrangement, and in the next part I may attempt adjustment as some appears necessary in both cases. For a couple of centuries, Cowries have been the delight of amateur shell-collectors, and their varied vivid coloration has caused the nomination of very many colour-varieties. The Schilders have catalogued 165 species only which they divide into geographical races and subraces, altogether ignoring the abovementioned colour variations. They have, however, en- deavoured to make use of some of colour-varietal names for these geographical races with confusing effect. From experience, it is suggested
