Part III. — Twelfth Annual Report 



privilege of consulting literature that would otherwise have been difficult 

 to get hold of. I have also to acknowledge my indebtedness to Mr 

 Webster of the University Library for valuable assistance in this respect. 



Before proceeding to describe the animals that have been added to the 

 Forth fauna during the past year, it will perhaps be useful and interesting 

 if in some measure, at least, I try to show what progress has now been 

 made towards the attainment of a- better knowledge of the Invertebrate 

 fauna of the Firth of Forth through the investigations that have been 

 carried on in the estuary under the direction of the Fishery Board for 

 Scotland, and also the amount of success that has attended these investi- 

 gations. For the present I can only indicate what has been accomplished 

 in the study of the Copepoda, leaving the other groups to be dealt with 

 later on. In this attempt to summarise the results of the work that has 

 been done during the last few years among this important group of the 

 Crustacea, I propose, in the first place, to give a list of all those species 

 obtained in the Firth of Forth that have already been described and 

 figured in the ' Monograph of the British Copepoda,' published in 1880 ; 

 this will form a basis for, and an incitement to, further work by showing 

 what blanks have yet to be filled up ere this part of the list can be con- 

 sidered complete. Second, I propose to give a list of those species 

 obtained in the Firth of Forth which are not included in that Monograph, 

 but have been added to the British fauna by other investigators since 

 the publication of that work. A third list will include those species that 

 have been added to the British fauna as the direct result of the Scottish 

 Fishery Board's Investigations. And a fourth list will contain those 

 species, apparently new to science, discovered during the progress of the 

 investigations referred to. 



The species are arranged in alphabetical order, and those described in 

 this report are included with the others in the various lists. 



List No. I. 



The Copepods contained in this list include only those species that are 

 described in the 'Monograph of British Copepoda,' by Dr Brady, 

 published in 1878-80. (Fresh- water species are not included in the list.)
