IV.—The Eggs and Larvæ of Teleosteans
Published online by Cambridge University Press: 06 July 2012
Extract
The purpose of this memoir is (1) to make known a number of drawings and descriptions of the eggs, embryos, and larvæ of the species of Teleosteans which I have been able to study at the Scottish Marine Station; (2) to review as comprehensively as possible what is known at the present time concerning the structure of the embryos and larvæ of the species of Teleosteans, and to discover what features are common to each family or each order; (3) to discuss the changes which take place in the protoplasm and nucleus of the mature ovum immediately after it is shed, both when fertilised and when unfertilised. The ova of the following species were taken directly from the parent fish, and artificially fertilised. The necessary operations were carried out, in some cases by myself, on board fishing boats—usually steam trawlers from Granton. In many instances I did not myself go out in the boats, but the ova were obtained and brought to me at the laboratory by Alexander Turbyne, keeper of the station. But in every case there is no uncertainty as to the species of the fish from which the ova were taken; if there was any doubt, specimens of the parent fish were brought with the ova.
