FAUNA LIST
The list has been arranged according to the system and
nomenclature of the 1957 edition of the Plymouth Marine Fauna
with the exception of the Phylum Mollusca which follows the
system of Winckworth (1932 and 1951). The records all come
from the surveys made by the Central Electricity Research
Laboratories and Ministry of Agriculture, Fisheries and Food
between 1959 and 1965 unless references given indicate otherwise.
Full details of the collections made are included in a series of
restricted circulation notes and reports. A type collection of
many of the specimens is held by the Central Electricity Research
Laboratories.
