The present report deals with the Free-Swimming, Littoral and Semi-Parasitic Copepoda 
obtained principally from the plankton collected by the various tow-nets employed during the 
investigations. Three bottles containing washings from dredged invertebrata were also sent to me 
for examination. These washings contained a number of interesting species of Harpacticoida, 
Lichomolgidae and Asterocheridae which would probably never have been secured by 
the ordinary method of tow-netting. 
The total number of collections sent for examination was 86, and represents the following 
methods employed on board H. M.S. ‘Siboga’.

Only selected samples of the Copepoda were at first submitted for investigation. Every 
Copepod in each of these samples was identified and separated out. This furnished some 
indication of the value and richness of the material. Finally the whole of the crustacea plankton 
was sent for examination at the end of 1902. Owing to the contents of the cases being 
incompletely declared, and a portion being preserved in dutiable spirits, very great difficulty 
was experienced in getting the collection released by the British Customs Authorities at the 
Port of Entry into the Kingdom. After considerable correspondence and representation of the 
_ scientific value of the material, the cases were set free on payment of the duty charge on one
