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.
