SECTION B.-BIOLOGICAL INVESTIGATIONS, 



I. — ADDITIONS TO THE FAUNA OF THE FIRTH OF FORTH. 

 — PART VII. By Thomas Scott, F.L.S. (Plates III., IV.) 



Owing to continued efforts being made to work up what remains of 

 dredged and other material collected in various parts of the Firth of 

 Forth during recent years, and also to still further extend our investiga- 

 tions of the fauna of the Forth estuary, a considerable number of organ- 

 isms have, as the result of these efforts, been added to those described in 

 the Annual Reports of previous years. The additions this year comprise 

 one species of Pisces, twenty-eight species of Copepoda, and one species of 

 Trematoda. 



Descriptions of most of these have been already published,* descriptions 

 of others are in course of publication,! while several others are described 

 here for the first time. 



I am again indebted to my son, Mr Andrew Scott, Fisheries Assistant, 

 University College, Liverpool, for the drawings that illustrate this memoir. 

 My friend, Mr William Eagle Clark, identified for me the fish that is here 

 recorded ; Dr R. Blanchard, the eminent French naturalist, kindly 

 favoured me with the name of the Trematode fish parasite referred to 

 above, while Dr. T. Wemyss Fulton, F.R.S.E., Superintendent of Scientific 

 Investigations, by his uniform and kindly interest in our work, has done 

 much to make our work successful. I have also to acknowledge my 

 indebtedness to Captain Robert Campbell of the Fishery Cruiser * Gar- 

 land, for the assistance he is always, whenever possible, so ready and 

 willing to give.

 Triglops Murrayi, W. Eagle Clark, Ann. Scot. Nat. Hist., No. 13, 

 p. 23 (Jan. 1895). 

 Habitat. — A few miles west of May Island (28th Nov. 1890). 

 Though Triglops Murrayi was obtained in 1890, the species was un- 

 known to us at that time ; the specimen was therefore put aside till an 

 opportunity should occur for a study being made of its peculiar features. 

 It was thus allowed to stand over till last year, when it was sent 

 to Mr Eagle Clark of the Museum of Science and Art, Edinburgh, 

 who identified it as Triglops Murrayi, Gunther. In the Annals of 

 Scottish Natural History for January 1895, Mr Eagle Clark gives a 

 summary of all the known records of the occurrence of this fish since 

 its discovery on the west coast of Scotland by Dr Murray in 1885. 

 It does not appear to have been observed in the Firth of Forth previous 

 to 1890.
