27 sight of our shores. How you can help There is urgent need to continue to improve upon and expand the sightings network, to fill in gaps in coverage, and identify conservation problems. Everyone who visits the sea is urged to help by participating, ALL records being welcomed. The more individual records we have and the fuller the coverage around our shores, the more we can identify conservation threats that they face. If you see porpoises or dolphins very regularly, please do not take them for granted. Logging of every one of those observations would be extremely valuable. Guides, Forms and Other Publications To aid recording of sightings, an illustrated field identification guide has been produced (price 75p), and standardised recording forms have been developed. There is also available a report of a cruise carried out along the western seaboard of Britain and Ireland in summer 1980 with B/W illustrations of many of the species likely to be encountered, and maps of where they are to be found. The cost is £1. Please make cheques payable to Cetacean Group, and either allow for the cost of postage, or better still, include an SAE (size 9" x 6.5" or A5, for the guide; size 12.75" x 9" or A4 for the cruise report). Please address all correspondence to Dr. P. G. H. Evans, Secretary, Cetacean Group, c/o EGI Zoology Department, South Parks Road, Oxford, 0X1 3PS. Telephone 0865 247448.
