Stations 5231; 5233; 5240; 5246; 5287. Established in the Siboga 
plankton upon a single female from the Halmahera Sea in a vertical 
haul from a depth of 1,000 meters; not since found. A small number 
of females were obtained at these Albatross stations east of Mindanao 
and just north of the Siboga locality in vertical hauls varying between 
310 and 80 fathoms to the surface.

5231; 5246; 5287. Identified by Sars from 18 of these Albatross sta- 
tions and from 25 Monaco stations; and found at 10 stations in the 
Siboga list. With one exception, the Siboga specimens were taken in 
vertical hauls starting from depths of 80 fathoms or more, 15 hauls 
were from 30 fathoms, and one, indeed, was from 550 fathoms.

Scottocalanus setosus A. Scott, Copepoda of the Siboga-Expedition, monogr. 29a, 
pt. 1, p. 108, pl. 24, figs. 10-18, 1909. 
Stations 5185; 5231; 5487. Established by Scott upon female 
specimens from the western tropical Pacific and described in the Siboga 
plankton. These Albatross specimens are the first to be recorded since 
the original discovery, and they come from the same locality.
