COPEPODS GATHERED BY ALBATROSS—-WILSON 189 
Station 5320. Another species established by Sars in the Monaco 
plankton upon female specimens from the temperate Atlantic. It was 
recorded in the Siboga plankton from the Malay Archipelago but is 
not found in the other lists and the male still remains unknown. 
Genus CHIRIDIUS Giesbrecht, 1892 
CHIRIDIUS ARMATUS (Boeck) 
PLATE 22, Figure 310 
Huchaeta armata Boeck, Forh. Vid. Selsk., Christiania, vol. 14, p. 39, 1872. 
Stations 4646 ; 5185; 5208; 5231; 5285; 5651. Identified from these 
six Albatross stations and from 29 Monaco stations but not found in 
the other lists. All the Monaco stations were located in the northern 
Atlantic, but the first of these Aldatross stations is located off the 
Galapagos Islands and the second in the Philippines, making the first 
record from the Pacific. In this species both fifth legs of the male 
have rudimentary endopods as seen in the figure. 
CHIRiDIUS GRACILIS Ferran 
Chiridius gracilis FarRan, Fisheries Ireland. Sci. Invest., 1906, pt. 2, p. 30, pl. 2, 
figs. 1-3, 1908. 
Station 5382. Originally described by Farran from the northern 
Atlantic and afterward reported doubtfully off New Zealand (Farran, 
1929, p. 229) ; also doubtfully reported by Scott in the Siboga plank- 
ton from the Malay Archipelago. Not found in the other plankton 
lists and present here in the Albatross plankton only in the single 
Philippine haul listed above. The male is still unknown. 
CHIRIDIUS OBTUSIFRONS (Sars) 
Chiridius armatus Sars, Norwegian North Polar Exped., vol. 5, Crustacea, p. 
64, pl. 17, 1900. 
Chiridius obtusifrons Sars, Crustacea of Norway, vol. 4, p. 29, pl. 17, 1902. 
Stations 5185; 5227. Sars’ type specimens came from the ocean 
and were at first referred to the species armatus but afterward de- 
scribed as new in the Crustacea of Norway. The Siboga plankton is 
the only list in which this species is found, and even there the name 
is followed by a question mark. However, these two Albatross lo- 
calities are close to the one mentioned in the Siboga plankton and 
indicate that it is really a Pacific form.
