VIII.—Scottish National Antarctic Expedition: A Description of the Systematic Anatomy of a Fœtal Sea-Leopard (Stenorhynchus leptonyx), with Remarks upon the Microscopical Anatomy of some of the Organs.
During the Scottish Antarctic Expedition of 1892–93 Dr W. S. Bruce secured fœtuses of Stenorhynchus leptonyx and Lobodon Carcinophaga, and on his return passed them over, with other material, to Professor D'Arcy W. Thompson for the Zoological Museum of University College, Dundee. While some of the material has unfortunately been lost sight of during these twenty-one years, one specimen, viz. that of a fœtus of Stenorhynchus leptonyx, was still in existence, and was returned by Professor D'Arcy Thompson to Dr Bruce, who in turn asked me to examine and report upon it. Furthermore, during the voyage of the Scotia embryos of Leptonychotes weddelli were obtained by the Scotia naturalists, and these were passed on for description to Professor Waterston, at that time in the University of Edinburgh. It is on this material that the present monograph is based.
