Abstract

[No abstract is given for this work, it begins as follows] Family Dasyatidae. To the Parliamentary Report of the Marine Department of Queensland for 1902–3, the late Dr. Jas. R. Tosh contributed an appendix which is of importance to students of our marine biology. It is entitled "Notes on the Habits, Development, Etc., of The Common Food Fishes of Moreton Bay," and is illustrated by twelve plates. These depict stingrays, mullets, and various other fishes, and show the development of the eggs of the mullet, bream, blackfish (Girella), and others. All the species have been included in the Queensland List, but Tosh left a few without specific names, thus: Dasyatis sp. ... Heteroscarus sp. ... and Neopercis sp. ... The stingray is evidently Dasyatis fluviorum Ogilby, though this species is not a true Dasyatisas there is a fold, not a keel, below the tail, and would he better regarded as the orthotype of a new genus.
