42 THE INVERTEBRATE FAUNA 
CRUSTACEA. 
The groups which the following list overtakes are the 
Cirripedia, Amphipoda, Isopoda, Cumacea, Stomapoda, and 
Decapoda. A very full list of the Ostracoda of the east coast 
of Scotland, collected from the Aberdeenshire coast, Montrose, 
the Firth of Forth, etc., will be found in a paper by Professor 
G. S. Brady and Mr David Robertson, “On the Distribution 
of the British Ostracoda.”* We shall not attempt at present 
to treat either this group or the Copepoda. 
In the arrangement and nomenclature of the Amphipoda 
and Isopoda, we have followed Bate and Westwood’s 
“ British Sessile-eyed Crustacea,” a work from which we have 
derived the greatest assistance. 
We have used the lists, prepared by Metzger, of the 
Crustacea obtained by the German Exploring Expedition of 
1872. Many of the species in that report were not pre- 
viously recorded from the Forth.
