INTRODUCTORY REMARKS. 



In the paper on " The Marine Fishes and Invertebrates of Loch Fyne," 

 published in Part III. of the Fifteenth Annual Report of the Fishery 

 Board for Scotland, it is distinctly stated that the catalogue then published 

 could '* only be considered as preliminary to further research." It would 

 have shown unwarranted presumption on the part of the compiler of that 

 catalogue had he pretended that it could have in any sense been con- 

 sidered exhaustive : it was, as explained in the preliminary remarks, 

 neither more nor less than a compilation from the recorded results of past 

 investigations, so far as these were known to the writer, to which he added 

 certain information that had been obtained as the result of personal study. 

 And though the number of additions that now fall to be made, and the 

 recording of which forms the subject of the present paper, is very con- 

 siderable, this simply shows that the time when an exhaustive catalogue 

 can be prepared is not yet ; and that, notwithstanding all that has already 

 been done, the study of the Loch Fyne invertebrata will yield, for some 

 time to come, profitable and interesting results to the student who has 

 sufficient opportunities and enthusiasm to engage in it. 



The species that fall to be recorded in the present paper as additions to 

 the previous catalogue of Loch Fyne invertebrates number in all about 

 one hundred, and include representatives of the following groups : — (1st) 

 The Schizopoda (one species). (2nd) The Isopoda (one species new to 

 Britain). (3rd) The Amphipoda (four species). (4th) The Ostracoda 

 (fourteen species). (5th) The Copepoda (twenty-three species, five of 

 which are apparently undescribed, and two have required new genera to 

 be instituted for them)."^ (6th) The Annelida (one species, new to the 

 Clyde district). (7th) The Foraminifera (fifty-six species and varieties, or 

 double the number recorded in the first catalogue). 



* In the Appendix there are also descriptions of a new genus and species of Copepoda 

 from Kilbrannan Sound, Firth of Clyde.
