OF THE FIRTH OF FORTH. 3 
Echinids; (3.) the Testacea, being Gastropods, Lamellibranchs, 
and Cirripedes ; and (4.) the Sea-insects, among which we re- 
cognise Aphrodite aculeata. Sir Robert enumerates sixty- 
eight species of invertebrates. Of these many can be iden- 
tified with our commonest species ; others are more difficult 
of recognition under their somewhat lengthy but vague pre- 
Linnean designations. 
In 1809, Professor Jameson read to the Wernerian Society of 
Edinburgh a paper, entitled, “ A Catalogue of Animals of the 
Class Vermes, found in the Firth of Forth, and other parts of 
Scotland.” Under the title Vermes he includes, as was usual 
at this date, representatives of the various invertebrate sub- 
kingdoms. Jameson enumerates seventy-seven species from 
the Firth, among which the only Molluscs are two species of 
Tritonia, one of Doris and one of Chiton. He divides the 
Vermes into—(1.) Mollusca, including Nudibranchs, Asci- 
dians, Annelids, Holothurids, and Coelenterates; (2.) Testacea, 
of which Chiton is the only example given; (3.) Crustacea, 
including Echinids, Asterids, and Ophiurids; (4.) Coralla, 
being the Alcyonaria, Sponges, Polyzoa, and Sertularids ; 
and (5.) Zoophyta, including Pennatula, Hydra, and Coryne. 
In the same volume of the “ Memoirs of the Wernerian 
Society,” p. 370, is a paper by Captain Laskey, “An Account 
of North British Testacea,” in which he enumerates between 
sixty and seventy species of Gastropods, Lamellibranchs, and 
Cirripedes, obtained in the Firth of Forth. Much doubt, how- 
ever, has been expressed by distinguished conchologists as to 
the genuineness of many of the localities given in this paper. 
Among those who have largely contributed to our know- 
ledge of the fauna of the Forth, Mr H. D. 8. Goodsir, who 
promised to attain to an equal scientific eminence with his 
brother, the illustrious anatomist, must be mentioned with 
special praise and regret. He discovered many new genera 
and species in the Forth, to which reference will be made in 
the text of this paper. He joined the Franklin Expedition 
in the capacity of naturalist, and shared in its disaster. 
Many professors of the University of Edinburgh have from 
time to time investigated the fauna of the Forth, and of these 
Professor Jameson has already been mentioned; in more
