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.E.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 Ptock.
