R. Stebbing, of Tunbridge Wells, for his ever liberal 

 and painstaking assistance. 



Unfortunately there have been few workers on 

 the Amphipoda of the Firth of Clyde ; and the 

 literature on that branch of zoology, with the 

 exception of scattered reports, is confined to Messrs 

 Spence Bate and Westwood's valuable Monograph oj 

 the British Sessile-eyed Crustacea. It is now nineteen 

 years since the publication of that "work, and during 

 the intervening period there have been many addi- 

 tions and rearrangements in both genera and species. 

 In the following list I have adopted in some cases 

 the arrangement of Boeck's exhaustive work De 

 Skandinaviske og Arktiske Amphipoder. 



In preparing the list an endeavour has been made 

 to give the haunts and habits of the animals where- 

 ever opportunity occurred. With the exception, 

 however, of those found within tide-mark, this 

 could not always be satisfactorily done. 



The dredge, by which the greater number of 

 species is procured, allows few opportunities for 

 studying their habits. When an attempt is made 

 to do so in confinement in a glass jar or other 

 vessel, the conditions are so different from those 

 existing at a depth of from 10 to 100 fathoms at 

 the bottom of the sea, that little value can be 

 attached to the results. Those species most easily 

 attainable and most abundant inhabit the littoral 

 belt between high and low - water, chiefly under 

 stones and decaying sea- weed, where any number 

 may be procured with very little trouble. They 

 belong chiefly to the two genera Talitrus and 

 Orchestia. 



Besides with the dredge, good work can also be done 

 between tide-mark on the sandy shore and sheltered 

 bays, with a sieve that will allow the sand and mud 

 to be washed out but is close enough to retain the 

 animals. 



The surface-net is another successful appliance 

 yielding many forms of great interest. It can be
