FOREWORD 
Dr. Cuartes Brancn Wirson, author of this work, died on August 
18, 1941. A brief obituary was published in Science, volume 94, pages 
358-359, October 17, 1941. More intimate biographical notes formed a 
memorial supplement to the Westfield, Mass., High School Herald, 
volume 54, No. 1, October 17, 1941; the subject of an obituary note in 
The Colby Alumnus, volume 31, No. 2, pages 21-22, November 15, 1941; 
and a biographical note in the National Cyclopedia of American 
Biography, by Dr. Wilson’s son, Carroll A. Wilson. 
Inasmuch as the manuscript of this paper was not given editorial 
attention while Dr. Wilson was still living, special pains have been 
taken to check references, occurrences, station records, and lists of 
species collected. In this task I was assisted by Miss Lucile McCain, of 
the office of the head curator of zoology, United States National Mu- 
seum, who also prepared the list of literature cited; by Mrs. Mildred S. 
Wilson,! formerly assistant curator of the Museum’s division of marine 
invertebrates, who checked parts of the collection and verified certain 
identifications; and by Miss Gladys O. Visel, of the editorial division 
of the Smithsonian Institution. Such notes, emendations, and correc- 
tions as I have made, other than this foreword, are generally followed 
by the initials W. L. S. and are usually enclosed in brackets. Notes 
supplied by Mrs. Wilson have been similarly dealt with and are ini- 
tialed M.S. W. Mrs. Wilson also contributed the references made to 
two important works by R. B. Seymour Sewell (1913; 1929, 1932) deal- 
ing with the copepod fauna of the Indian seas that apparently escaped 
Dr. Wilson’s attention. Sewell anticipated several of Dr. Wilson’s 
first Pacific records for certain Atlantic species. 
The manuscript as received from Dr. Wilson contained no references 
to original descriptions of species or a list of literature cited. These 
omissions were supplied here at the National Museum. Besides pre- 
paring the “Literature Cited,” Miss McCain checked the citations 
against the original publications in every instance where these were 
obtainable in this country. 
Because of their pertinency, Dr. Wilson included his identifications 
of the copepods from several Pacific stations occupied by Alexander 
Agassiz in November and December 1897, while cruising through the 
Fiji Islands aboard the Yaralla (cf. List of Copepods Collected, 
p. 429). Also included are two species not collected by the Albatross, 
as well as non-A/lbatross material of a third species that Dr. Wilson
