EDITORIAL NOTE. 



Early in the spring of 189i the state geologist, N. H. AVinehell, 

 referred to me a letter from Professor C. L. Herrick containing two 

 propositions, viz. : (L) That the Snrvey accept and publish the present 

 revision of the report of 1884; (2) that the author be permitted to 

 make such use of the old report as he saw fit and publish the revision 

 independently of the Survey. After having been assured that the 

 errors of the 1884 report had been corrected and the report had been 

 bettered in other respects, it was decided, for reasons that seemed 

 sufficient, to accept the first offer, though the revision had been begun 

 and practically finished without the knowledge of any one connected 

 with the Survey. The manuscript was received during the last week 

 of October, 1894. 



The editorial work as well as the proofreading all fell to the zoolo- 

 gist of the Survey. The author's serious illness and his great distance 

 from the University made it impracticable to put any of this work 

 upon him. The work was at times very disheartening, but I did my 

 best, and trust that at least most of the errors and shortcomings of the 

 manuscript have been eliminated. 



In justice to the author the following matters deserve special men- 

 tion: 



The author's title,- " Synopsis of the Microcrustacea," etc., was 

 changed for reasons found principally in the primary destination of 

 the report and in the usage of some of our best and most generally 

 used text-books of zoology. 



For making reference only by author and date the, editor is wholly 

 responsible. The date is always an important and often a very essen- 

 tial part of a publication, and for that reason alone is far superior to 

 a reference by a purely artificial number. The superiority of an 

 abbreviated reference to a full or more or less mutilated citation is so 

 obvious that it needs no vindication. 



In the bibliography the editor has supplied the number of pages, 

 number of plates and similir data of detail from Taschenberg's 

 Bibliotheca ZooJogica, Zoologischer Anzeiger, ZooJogischer Jahresbericht, 

 and the Catalogue of Scientific Fajiers compiled by the Eoyal Society of 

 London. Where these data are wanting the citation could not be 

 found in these publications or could not be identified beyond a doubt- 

 In comparatively few cases could these data be obtained from original 

 sources. More or less gross discrepancies between the manuscript 

 and the publications noted above were very numerous as to date, title
