The following faunistic notes are offered as an indication of the chief results which have characterised our collecting operations during the present year. It is hoped that, short as they are, they may prove serviceable to British naturalists desiring to pursue special researches in marine zoology, but undecided as to the locality most likely to meet their needs. The notes are incomplete, owing to my absence from Plymouth during the earlier part of the year; but they are sufficient for the formation of an inference, since the results here described were obtained for the most part during only a fragment of the year—from June to September.
