Preface. 



It was originally contemplated that this volurae would be published 

 within the limits of the nineteenth centuiy. When the date of issue was 

 unavoidably postponed, the internal structure of the work no longer admitted 

 of any extensive remodelling. In the mean time, however, it so happened 

 that our knowledge of the Ämphipoda was enlarged by several important 

 conti-ibutions. Accordingly the survey of the literature, which had been 

 canied down with some completeness to 1898, was prematurely suffering 

 from that imperfection by wlueh all such surveys are eventually afflicted. 

 To remedy this inconvenienee so fal^äs^ä^ible, the editor has kindly permitted 

 the addition of many pages which bring the bibliography of the subject well 

 into 1905, with an occasional incursion even into the present year. 



In regard to the numerous species recorded as doubtful, it is desirable 

 to explain that in many instances no censure is intended of the original 

 descriptions. The doubtfulness often results only from the fact that recent 

 Classification has adopted features of distinction, the employment of which 

 could not easily have been foreseen at an earlier period. 



The nature of the present work includes acknowledgment of indebtedness 

 to innumerable authors. To the editorial staff of „Das "Tierreich" the thanks 

 of readers should be united with those of contiibutors, if the most unremitting 

 care in verifying citations is thought worthy of gi-atitude.
