These are stray notes on a few of the pelagic animals found in the Clyde. I noted down their occurrence whilst examining the plankton for medusæ. The records may be useful to students who intend working in the Laboratory at Millport, and should give them an idea as to the time of year at which these animals occur. They may also be useful for comparison with other years and other localities. Most of the species have been previously recorded for the Clyde, and the few which are not mentioned in the “Fauna of the Clyde,” are fairly common on the British coasts. As these notes form a kind of appendix to my Report on the Medusæ, I have curtailed this introduction to avoid repetition.
