Notes on some British Nudibranchs.

Abstract

The following notes are the result partly of an examination of various living specimens at Plymouth in the spring of 1905, and partly of the study of preserved material most kindly placed at my disposal by Mr. E. J. Allen and Mr. W. I. Beaumont, of the Laboratory, Plymouth, Mr. W. E. Hoyle, of the Manchester University Museum, and the Council of the Hancock Museum at Newcastle. I must also express my thanks and obligations to Mr. T. J. Evans, lecturer in Biology at the University of Sheffield, who has prepared for me sections of the smaller specimens and embodied the results in drawings which will add very materially to any value which this paper may have.
