POLYZOA OR BRYOZOA. 



In 1862 Dr M'Bain gave a short list of Marine Polyzoa 

 from the Firth of Forth, in the first edition of Wood's 

 East Neuh of Fife, and they were further investigated by 

 Charles W. Peach, who furnished Leslie and Herdman with 

 many good records for this section of their " Invertebrate 

 Fauna " of the Firth. Some earlier records by Coldstream, 

 Grant, Landsborough, and others are cited in the works 

 of Johnston and Hincks.^ From these sources, supple- 

 mented by their own investigations, the authors of the 

 "Fauna" were able to present a list of 61 species. To this 

 Henderson (I.e.) added 6,^ and among Pearcey's records I find 

 other 3 additions,-^ making 70 in all. One would expect a 

 good many more than this to occur in the Forth — say 80 to 

 90 — seeing over 100 are enumerated from the Firth of 

 Clyde. 



The following fresh-water Polyzoa were recorded from the 

 neighbourhood of Edinburgh by Sir J. G. Dalyell and Pro- 

 fessor G. J. Allman, and doubtless two or three others will 

 yet be found. The records are for the most part taken from 

 Allman's Monograph of the Fresh-Water Polyzoa, published 

 by the Ray Society in 1856. 



Cristatella mucedo, Cuv. ( = (7. mirabilis, Dll,^) — Duddingston 

 Loch, and pond at Binns House, Linlithgowshire (J. G. D.); 

 Union Canal, Edinburgh (G. J. A.), 



Plumatella repens (L.) — Blackball Pond, and old quarry at 

 Fenton Tower, Haddingtonshire (J. G. D. in Rare and Rem. 

 Anim.); pond near Davidson's Mains (W. E.). 



Fredericella sultana (Blum.)— Union Canal (G. J. A.); and 

 more recently, 1888 (W, E.). 



Paludicella ehrenhergi, v. Ben. — Union Canal (G. J. A.). 



Dalyell's Alcyonella stagnorum, from a pond in Heriot Row, 

 Edinburgh, was, according to Allman (op. cit., p. 71) probably a 

 young condition of Plumatella.
