279 The Coypu By C. Owen THE Coypu or Nutria, Myocastor coypus, has been found in Essex. A colony established itself on the north bank of the Stour (near Dedham) some years ago and no doubt that at this time the first occurrence in Essex took place by 1955. In 1958 young Coypu were observed on the Essex side of the Stour near Lamarsh. In 1959 a young animal was killed at Rayne and the nearby Pods Brook was searched for three miles by officers of the Pest Division of the Min. of Ag. & Fish. None were found. In spring 1960 two reported near Stebbing and caught by officers of the Pest Division were given to Mr. Owen at the Colchester Natural History Museum where they are still alive. There is an unconfirmed report (July 1960) from East Mersea, but further records will be welcomed by the author. Essex Naturalists' Trust Ltd. THE inauguration of the Essex Naturalists' Trust on 3rd October at Chelmsford was a notable event of 1959. Her Majesty's Lieutenant of Essex, Colonel Sir John A. Ruggles-Brise, C.B., O.B.E., T.D., J.P., consented to be the Trust's Patron, and Mr. H. R. Tutt, J.P., a pioneer of nature conservation in Essex, accepted an invitation to be the Trust's first President. The first aim is to record all places of scientific interest in the county involving a thorough survey of each site from scientific, archeological and historical aspects. The Trust will also endeavour to protect such sites which are threatened and which warrant preservation. Some reports have been published in 1960, and on 5th March 1960 the first Annual General Meeting was held where further plans for the development and organisation of the Trust were outlined. The Trust invites the co-operation of all having an interest in the natural history of the county. Secretary of the Trust is T. H. C. Bartrop, Oak Tree Cottage, Margaretting, Ingatestone.
