A HISTORY OF KENT time several very important groups have been more or less completely overlooked by all of us. For example none of the lists contain any of the Cephalopoda^ which I think I should have obtained if I had used my small traw^l at Queenborough. When the Copepoda which I had collected and preserved in alcohol were examined it was found that they had deteriorated too much for proper identification. The sea spiders {Pantopoda) seem also to have been overlooked, except a small specimen oiPycnogonum littora le ionnd by me at Queenborough. The Crustacea and fish are dealt with by other authors. Making due allowance for imperfect collecting, there appears to be a marked difference between the animals along the north and south-east shores of Kent, and still more so between both and the coasts of Essex and Suffolk. A number of animals which I have found in considerable quantity on one side of the Thames estuary I have never seen on the other side ; and I am surprised to find how much difference there is between the species collected by others near Whitstable and Folkestone and those I have myself collected during many years along the coasts of Essex and Suffolk. I much regret that it is now out of my power to thoroughly investigate this wide and difficult question of local distribution. gy
