457 NOTES ON, AND DESCRIPTIONS OF AUSTRALIAN FISHES. NO. 2. By Allan R. McCulloch, Zoologist, Australian Museum. (By permission of the Trustees of the Australian Museum). (Plates xxxvii.-xli. and three Text-figures.) The following paper is a collection of miscellaneous notes and descriptions similar to that of Part 1, published in These Proceedings, Vol. xl., pp. 260-277. Most of the fishes dealt with have been hitherto insufficiently described and imperfectly known, and are therefore here figured and redescribed in detail. The synonymy of several has been studied, and is presented in a new form, while others are recorded from Australian waters for the first time. One is regarded as a new species. Family CARCHARHINIDAE.
