THE INVERTEBRATE FAUNA OF THE FIRTH OF FORTH. 29 
PROTOZOA. 
In this list the Foraminifera only are catalogued, the 
other Protozoan groups being omitted for the present, as 
they require very special work. With the exception of a 
few species of Infusoria and Lobosa, noted by Dr Strethill 
Wright, they have been entirely neglected by workers in the 
Forth. The Sponges, now considered as a group of the 
Metazoa, will be treated separately. 
In the preparation of the following list we were very largely 
indebted to a valuable paper by Mr H. B. Brady, F.R.S., on 
“ Brackish-Water Foraminifera,’* one of the localities which 
he investigated being the upper basin of the Forth. We have 
also used the list published by Professor Franz Eilhart 
Schulze, in the report of the German Expedition of 1872.+ 
In the identification of the forms which we have ourselves 
obtained in the Forth, we have had the kind assistance of Mr 
Frederick Pearcey, to whom we would now express our 
thanks. Our material was dredged in 5 fathoms, on the 
oyster bank, near Inchkeith. We have added a number of 
forms to those previously recorded from the Forth, but do 
not doubt that further work will very largely increase the 
list. Mr Pearcey reports that the gathering in which the 
Foraminifera were found consisted of quartz grains, small and 
broken shells, Annelid tubes, and fragments of Polyzoa, 
Hydroids, and Echinoderms. Mr H. B. Brady’s specimens 
were obtained about 20 yards from the pier at Bo’ness, in 3 to 
4 fathoms, the bottom consisting of soft, slimy mud. Those 
in Franz Eilhart Schulze’s list were got in the beach sand 
between Portobello and Fisherrow, and near the Bass Rock. 
Mr Brady’s specimens are marked (HZ. B. B.).
