Introductory. 



In the following catalogue an endeavour has been made to include, as 

 far as possible, the various species of marine fishes and invertebrates that 

 are known to have been obtained in Loch Fyne. But though the records 

 brought together here — the most of which are believed to be authentic, — 

 comprise a large number of fishes, and include representatives of almost 

 every group of the marine invertebrates, the catalogue can only be con- 

 sidered as preliminary to further research. The investigation of the 

 lower forms of life existing in Loch Fyne has already been in some 

 respects very successful, and has yielded interesting results ; still, there are 

 several groups of the Invertebrata, such as the Tunicata, the Polyzoa, the 

 smaller Crustacea, the Aunelida, the Ccelenterata, and the Porifera, that 

 have only been very partially studied, and it may reasonably be expected 

 that numbers of species belonging to these various groups will yet be 

 discovered in Loch Fyne. 



In this catalogue the total number of species enrolled is 837, which 

 includes several not before recorded from the Clyde, and also one Copepod 

 new to Britain, and one new to science. 



An appendix at the end of the catalogue of the Loch Fyne fauna contains 

 records and descriptions of several new and rare species that have been 

 observed during the past year in the seaward part of the Clyde area, and 

 which, therefore, could not find a place in the catalogue. 



These records include three apparently undescribed species of Cop epoda 

 two Amphipods, and a parasitic Isopod, new to Britain ; and a few others 

 that are either new records for the Clyde, or that refer to species that 

 are comparatively rare. 



As Calanus finmarchicus is a very important constituent of the food of 

 fishes, attention is also directed in the appendix to three different kinds 

 of parasites that have been found more or less infesting the Galani in the 

 Firth of Clyde.
