NOTES ON THE MAMMALS OF ESSEX 185 members in the south of Essex. According to J. Wentworth Day, one area which has more than its share of foxes is that of Tilbury Docks and their hinterland. Foxes are also recorded from gardens in Dovercourt (S. A. Peck). Records of foxes occurring in urban areas are particularly requested. Badger: Meles meles meles (Linnaeus). The survey of Badgers in Essex has progressed steadily and a considerable amount of knowledge of the distribution of Badgers and their setts has now been built up. A comprehensive report on the Badger in Essex, by D. Scott, was published in 1960, and it is recommended that reference should be made to this paper. Since the publication of this report, several new setts have come to light. Two of these are in the Halstead area, and this fact is encouraging because north Essex has so far yielded few new records of the Badger compared with the south of the County. In south-west Essex, in the Epping and Hainault Forest areas, the Badger setts under close observation have produced fifteen cubs in 1961, and fourteen in 1962, which compares favourably with past years and seems to indicate that the animal is holding its own. In the south, the South Essex Natural History Society has been studying the Badger for some years, and at present a further ambitious programme is under way. It has been decided to co-operate with the National Badger Survey of the Mammal Society of the British Isles, and this arrangement will no doubt be mutually beneficial. Otter: Lutra lutra (Linnaeus). Most of the earlier records were from the River Blackwater and the River Colne, although several other localities are mentioned. In 1957, it was stated by G. Dent (in private corres- pondence) that the Otter was "regularly incident on all the major rivers of the county", and that their numbers had remained con- stant, possibly increasing a little, over 50 years. In more recent years, the Otter is recorded from Bradwell, Wrabness, Canvey Island, the River Roach, the River Stour, and Abberton Reser- voir. Even when one is certain that the Otter is present in a particular place, direct observation is notably difficult owing to the animal's secretive habits, and therefore many records are based on indirect evidence such as tracks and droppings. Stoat: Mustela erminea stabilis Barrett-Hamilton. Laver states (1898) that the Stoat was very common through- out Essex. It now appears to be scarce in many of its former haunts. It was once common in the Chelmsford and Danbury areas, for instance, but is evidently scarce there now. Recent records are sporadic and include Stoats either shot or seen at Bradwell, Skipper's Island, Wivenhoe Park, and in the grounds of Wansfell, the college at Theydon Bois. It is hoped that more active recording would show this species to be less uncommon than the present records suggest.
