 IN CETACEA

INTRODUCTION 



THE compilation of a catalogue of the worm parasites of Cetacea was undertaken 

 some time ago at the request of Dr Stanley Kemp, F.R.S., and of the Discovery 

 Committee. The hst now presented is, it is hoped, as complete as it is possible at the 

 present time to make it, though our knowledge of many of the forms mentioned is very 

 scanty, and the systematic position of some of them remains uncertain. 

 The catalogue is divided into three sections : 



(i) A list of the parasites, in which are given their synonyms, references to the more 

 important literature upon them, and the hosts from which they have been recorded. 

 The parasites are here arranged, as far as possible, in systematic order, and are classified 

 under their families, and these again under the headings of the four principal groups, 

 Trematodes, Cestodes, Nematodes and Acanthocephala. No attempt has been made 

 to give a complete bibliography for every species mentioned, but the works referred to 

 include those in which descriptions of the species are given or their systematic position 

 discussed, or in which references to further literature may be found. The date of 

 publication follows the author's name, difl^erent publications in the same year being 

 distinguished by the letters «, b, etc., following the date. Where the date is followed by 

 a number, this is a page reference. The full references will be found by turning to the 

 bibliography in the third section. 



(2) A list of the hosts, with the parasites recorded from each. In this section the 

 names of the hosts are arranged alphabetically, and their principal synonyms and ver- 

 nacular names, when known, are given. The names of the parasites are again arranged 

 systematically. 



(3) A bibliography, arranged in the alphabetical order of the authors' names. 



The writer is greatly indebted to Sir Sidney F. Harmer, F.R.S., for very kindly 

 checking the names and synonyms of the hosts. The synonymy of many of the Cetacea 

 is extremely involved, and it is sometimes impossible to be certain what species of whale 

 is meant by authors who have recorded parasites from these animals.
