142 THE ESSEX NATURALIST. Mrs. Florence Vandepeer, of "Glenwood," Church Hill, Loughton. Mrs. Lilian Wilson, of "Pittencrieff," The Uplands, Loughton. Mr. Thorrington exhibited specimens of two succulent groundsels from South Africa, namely, the Candle-plant (Kleinia articulata) with evil-smell- ing flowers which are attractive to flies, and the African Ragwort (Othonna crassifolia). Mr. Scourfield exhibited Ricciocarpus natans, an uncommon liverwort which has only recently been recorded, by himself, from Epping Forest. He also showed a series of lantern-slides of various marine organisms— actual specimens, not photographs—prepared by the late Dr. Sorby and now in the possession of Sheffield University.1 Mr. Avery exhibited eleven Essex water-colour sketches by Major Bamford, comprising views of Fryerning Mill; St. Andrew's Church, Fing- ringhoe; Willis' Farm, East Hanningfield; St. Andrew's Church, Heybridge; the old bridge at Kelvedon; St. Mary's Church and All Saints' Church, Maldon; Newland Hall, Roxwell; All Saints' Church, Great Oakley; Black Chapel, North End, Great Waltham; and Mill at Walton-on-the-Naze. The Hon. Secretary exhibited a cardboard disk and a metal cap, covers to a glass milk-vessel, which had been pecked into holes by a Blue Tit in its determined attempt to get at the cream in the vessel; they came from Leigh-on-Sea. Similar damage to milk-covers has been recently noted at Loughton and in Hertfordshire, and in each case a Blue Tit was seen to be the culprit. The Curator also showed a series of prints and photographs of Havering- atte-Bower and Hornchurch from the Club's Pictorial Survey collection. He also exhibited a specimen-cabinet of the extensive Mera Collection of British Lepidoptera which had just been presented to the Stratford Museum, contained in two large glazed mahogany cabinets and six smaller mahogany cabinets, a most valuable acquisition. Thanks were accorded to the various donors and exhibitors. Mr. Edgar E. Syms then read a paper entitled "An Account of the British Snake-flies (Raphidia)," which he illustrated by a large number of lantern-photographs; and he was followed by Mr. Hugh Main, with "Further Notes on Methoca ichneumonides," which also was illustrated by an extensive series of lantern-photographs taken by the author. On the President's proposition, the thanks of the meeting were passed to Messrs. Syms and Main for their communications. The meeting then resolved itself into a conversazione for the inspection of the various exhibits. ORDINARY MEETING (680TH MEETING). SATURDAY, 31ST JANUARY, 1931.
