The ponds on the Beach are of considerable extent, and 

 greatly resorted to by wild fowl. We observed the follow- 

 ing:— Anas Boschas (wild duck), Larus canus (common 

 gull), Larus ridibundus (black headed gull), and Larus 

 argentatus (herring gull.) In the ponds we found very 

 large specimens of Limnea stagnalis (pond marsh snail), 

 and some very curious caddis worms, with great variety of 

 Entomostraca. xi-'"' ^"^
