35 Foraminifera — the only Protozoa they give — in their 

 " Invertebrate Fauna " of the Firth, communicated to 

 this Society in 1880-81.^ One addition, Astrorhiza limicola, 

 Sand., was reported by Dr J. E. Henderson in 1884.2 Since 

 then the list has been greatly extended by the naturalists to 

 the Fishery Board, Dr T. Scott adding 48 species,^ and 

 Mr Pearcey a further contingent of apparently no less 

 than 71.* So far as I am able to make out, there have 

 been at one time or another about 160 Ehizopods (practically 

 all Foraminifera) recorded from the estuary, and a good many 

 more — say what would bring the list up to 200 at least — no 

 doubt remain to reward further work. No Radiolaria have 

 been recorded, and it may well be that none occur. 



Of non-marine Ehizopods (Sarcodina) there have been but 

 few records. In a paper presently to be referred to, Scott 

 and Lindsay mention half a dozen species obtained in a 

 pond on the Braid Hills, and a few years earlier (1891) 

 Dr Scott recorded four from Loch Leven.^ 



During the years 1896-1898, Messrs T. Scott and J. 

 Lindsay made a systematic investigation of the micro-fauna 

 (and flora) of the " Upper Elf Loch," the tarn on the top of 

 the Braid Hills, and in an excellent paper published in the 

 Transactions of the Edinburgh Field Naturalists and Micro- 

 scopical Society, vol. iii., they give (pp. 381, 382) a list of the 

 Protozoa, which I understand were identified for them by 

 Mr John Hood of Dundee. This list contains 69 names, 

 (I here exclude Chcetonotus), 6 of them belonging, as 

 above-mentioned, to the Ehizopoda, 30 to the Flagellata,^ 

 31 to the Ciliata, and 2 {Podo'phryce) to the Suctoria; and 

 it is, we may reasonably suppose, fairly representative of 

 the Protozoan life in other ponds in the area. To test
