V. SOME ADDITIONS TO THE FAUNA OF THE FIRTH OF 

 FORTH WITH NOTES OF SOME RARE EAST COAST 

 FORMS. By Thomas Scott. 



Since the publication of the Revised List of the Crustacea of the Forth 

 in the last Report of the Fishery Board for Scotland, several interesting 

 additions have been made to some of the groups therein described, and it 

 has been considered desirable that these should now be recorded, as well 

 as some species belonging to the Protozoa, the Echinodermata, the 

 Mollusca, and Pisces, which hitherto do not appear to have been observed 

 within the limits of the estuary. Though the chief object of the present 

 paper is the recording of species new to the fauna of the Firth of Forth, 

 reference is also made to rare and interesting organisms which have from 

 time to time been observed while engaged in the trawling experiments carried 

 on, under the directions of the Scientific Committee of the Fishery Board, 

 in the Firth of Forth, in the Moray Firth, and in the Firth of Clyde. 

 Though the recording of such discoveries may be of secondary importance 

 when compared with the Board's other investigations, yet this tends to 

 show that the work that is being carried on is benefiting science in various 

 ways. 



INVERTEBRATA. 



FORAMINIFERA. 



In a valuable paper by Mr H. B. Brady on Brackish- water Foraminifera, 

 several species are recorded as occurring in the higher reaches of the 

 Forth, particularly in the vicinity of Bo'ness. Professor Franz Eilhart 

 Schulze, in the Report of the German Expedition of 1872, gives a list of 

 species observed mostly in the lower parts of the estuary during that 

 expedition, all of which are included in Leslie and Herdman's Invertebrate 

 Fauna of the Firth of Forth. The Foraminifera recorded in that work com- 

 prise three species of Miliolido?, two of Lituolidce, thirteen of Lagenidce, 

 fourteen of Globigerinida, and three of Nummulinidce ; to these Professor 

 J. R. Henderson added Astrorhiza limicola, Sandahl. The following are 

 some further additions of species (twenty-three in number), that have been 

 observed while collecting data in connection with the trawling experiments.

 one of the specimens was perfect, the others were young.

Habitat. — One specimen, near Inchkeith, 10 to 12 fathoms. The 

 specimen has unfortunately been damaged but is still perfect enough for 

 identification. This species has been found in the cold water channel 

 near the Faroe Islands in over 500 fathoms.
