REPORT OF THE COUNCIL. 137 Routine work at the Club's two museums has gone on steadily, and valuable accessions have been announced and exhibited at our meetings. The visit of our Patron, the Duke of Connaught, to the Forest Museum last July, when he expressed his admiration of the display of wild flowers made on the occasion, should not be passed over without record. The Library at the Stratford Museum continues to grow : 107 volumes have been bound during the year, and the total number of volumes now in the Library reaches 6,100. The Pictorial Survey of Essex now includes some 7,615 items, comprising photographs, prints and maps, mounted in 58 albums ; no fewer than 866 items have been mounted during the year. Two parts of the Essex Naturalist have been issued, at regular intervals, during the year. Mr. Barns has compiled and published two instalments of his "General Index" to Volumes 1 to 22. The attendances of members at our meetings have been well maintained, ranging between fifty and seventy at our indoor gatherings, and averaging 35 to 40 on the field meetings. The Fungus Foray in October, as usual, attracted over 120 members and visitors, notwithstanding very unfavourable weather on the occasion. In conclusion, your Council wishes to record its grateful thanks to all donors of specimens, exhibitors and others who have, in very various ways, contributed to the welfare of the Club and to the success of its meetings. Black-throated Diver at Walthamstow.—Mr. F. R. Finch reports, in British Birds for March, 1931, the occurrence of a single Black-throated Diver (Colymbus arcticus arcticus L.) on one of the Walthamstow Reser- voirs on December 29th, 1930. The identification was confirmed on January 1st, 1931, by Mr. W. R. Glegg.—Editor. New Collembola in Epping Forest.—Mr. H. Womersley, A.L.S., F.E.S., in the Annals and Magazine of Natural History for July, 1930, describes and figures a new species of Collembola which he found as a solitary specimen under loose bark on a rotten log in Epping Forest, near Loughton, in February, 1930. He has given the new form the name of Paratullbergia concolor, gen. et sp. nov., and has deposited the specimen in the British Museum.—Editor.
