302 THE PAUNA OF THE EXE ESTUARY. 



StatioxN 7. BETWEEN STARCEOSS AND COCKWOOD. 



In the first half the ground consists of gravel and shell debris, with 

 a thin (h to 2 inches) layer of muddy sand. As on the gravel of 

 Station 4, Lnnice concMlcga is very abundant, whilst Arcnicola marina 

 is not frequent.

Station 8. BETWEEN STARCROSS AND COCKWOOD. 



The ground now described lies to the south of Station 7, and differs 

 from it in being more sandy and less muddy. The soil consists of 

 gravel and shell debris, covered with about six inches of sand. In 

 consequence of this change in the character of the soil there is a 

 considerable increase in the Polychiete fauna, whilst Molluscs almost 

 disappear.
