A HISTORY OF SUFFOLK No attempt has been made in recent years to catalogue the marine flora of Suffolk, the list of sea-weeds in Henslow and Skepper's Flora of Suffolk (London, i860) (H. & S.) being the most recent known to me. These authors were doubtless greatly assisted in compiling their list by the account of the Norfolk and Suffolk algae published by Messrs. C. J. and James (afterwards Sir James) Paget in their Sketch of the Natural History of Yarmouth in 1834. Various Suffolk localities are also mentioned in Dawson Turner's Synopsis of the British Fuci, Dillwyn & Turner's Botanist's Guide (O.B.G.), Greville's yfl^ae Britannic^ (Grev.), and Harvey's Phycologia Britannica. I have myself collected at various points on the Suffolk coast, and my friend Mr. George Massee of the Royal Herbarium, Kew, has kindly presented me with a number of specimens collected by him at Felixstowe. The nomenclature used in the present list is that of my Catalogue of the British Marine Algae. No/e. — The writer, the late Mr. E. A. L. Batters, F.L.S., had himself gathered most of the species here recorded for Suffolk, or had seen specimens from it. In other cases the source of information is given.
