Messrs Leslie & Ilerdman on Invertebrata of Firth of Forth. 215 



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 Eobertson, " 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.
