This species is a moderately large form with a pointed forehead. It appears to be 

 generally distributed throughout the great oceans. 



3. Oithona minuta T. Scott.

Oithona minuta A. Scott, 1902, p. 409. 



Oithona minuta Thompson & Scott, 1903, p. 255. 



Twenty specimens belonging to this small form were obtained from the plankton collected 

 at Station 142. 



This species is very readily overlooked and requires some care in its determination. 

 Van Breemen (1908) states that Oithona minuta Kriczagin is identical with Oithona nana 

 Giesbrecht, but not with Oithona minuta T. Scott. 



Oithona minuta has only hitherto been recorded from the Gulf of Guinea, from the 

 Red Sea, and from the Indian Ocean round Ceylon. 



24. Family Longipediidae. 

 Genus Longipedia Claus, 1863. 



The members of this genus are readily separated from all the other Harpacticoida by 

 the very long endopodite of the second pair of feet. 



Three species were represented in the material collected by the 'Siboga' in the Malay 

 Archipelago. One of the species does not appear to have previously been described.
