THE BRYOZOA OF SUFFOLK. PREI.IMINARY

LIST.

THE Bryozoa, formerly called Polyzoa, are now considered to constitute a phylum of paramount rank and of dignity equal to the Vertebrata, Standing popularly between the Shell-fish and Seaurchins, Echinodermata. But few of the Freshwater kinds of this group remain to be found here, though a very great number of the Marine ones, of which no less than a hundred and twentyfive species are known to occur at Plymouth, still await discovery in shrimpers' refuse, at the tide-line, and about the artificial bulwarks of our coast towns. T h e present short list of available local kinds was compiled (along with that of the Rotifera, supra) with the object of calling attention of our younger Members to the group and so, it is hoped, of giving a fillip to their study bv our Society. A s f a r a s Freshwater ones are concerned, Hartmeyer's 1909 Bryozoen in ' Die Susswasserfauna Deutschlands' has been followed ; and in most others, to which additions should easily be made, Hincks' 1880 ' British Marine Polyzoa' is adopted.

1936 OCTOBER.—Following the sharp frost of the night of 2nd3rd, came the first Redwings, of which two were seen to arrive from the east and others were heard calling overhead at night. An injured Richardson's Skua was found on the beach on 3rd, and for two or three weeks it survived in my garden, being fed on sliced herrings. A Bernicle Goose, which turned up at the children's playground on the denes and stayed there for three or four days, was so absurdly tarne that we considered it as an escape. On 1 Ith Rook s and Jackdaws were first noted arriving from the east. T h e first Shore Lark was seen upon Corton beach ; two more were at Corton on 18th, and five on Lowestoft denes the following day. On 20th there was a strong westerly wind and a great immigration of Starlings was n o t e d ; the following day fewer Starlings, but many flocks of Skylarks were Coming in.
