COPEPODS GATHERED BY ALBATROSS—WILSON 233 
5120. This species was very widely distributed and was also found in 
the Monaco, Szboga, and Carnegie lists but nowhere abundant. The 
statement made by Rose in his report on the surface copepods of the 
Monaco plankton (p. 19), “Les espéces du genre Gaetanus vivent ex- 
clusivement en profondeur, et ne sont jamais capturées en surface, 
méme la nuit,” does not apply to this species. It is true of most of the 
species, but this one is sometimes captured at the surface even in the 
daytime. 
GAETANUS MINOR Farran 
Gaetanus minor Farran, Ann. Rep. Fisheries, Ireland, 1902-08, pt. 2, app. 2, p. 34, 
pl. 5, figs. 1-11, 1905. 
Stations 3982 ; 4678 ; 4687; 4701; 4719; 4722; 4734; 4753; 5120; 5186; 
5246 ; 5296; Marokau Island anchorage, Low Archipelago. Originally 
found in the Atlantic by Farran and reported in the Monaco plankton, 
this species appeared from the Pacific in the Siboga and Carnegie 
planktons. 
GAETANUS PILEATUS Ferran 
Gaectanus pileatus FARRAN, Report on the sea and inland fisheries of Ireland for 
1901, pt. 2, app. 7, p. 16, pl. 17, figs. 1-11, 1903. 
Stations 3800; 4665; 4679 ; 4683 ; 4685 ; 4687; 4700; 4705; 4707; 4708; 
4719; 4721; 4722; 4730; 4732 ; 4734; 4757 ; 5120; 5185; 5287. Identified 
by Sars at 15 of these Albatross and at 54 Monaco stations; present in 
the Siboga list as G. caudani. 
GAETANUS RECTICORNIS Wolfenden 
PLATE 23, Figures 340-341 
Gaetanus recticornis WOLFENDEN, Deutsche Stidpolar-Exped., 1901-03, vol. 12, 
Zool., vol. 4, fase. 4, p. 228, fig. 16a—c; pl. 26, fig. 13, 1911. 
Stations 76; 4646; 4655; 4664; 4665; 4676; 4679; 4681; 4717; 4719; 
4722. Originally established by Wolfenden upon specimens from the 
southern Atlantic and not appearing in any of the plankton lists. 
Hence these A/batross specimens identified by Sars from all but one of 
these stations constitute the first record from the Pacific. The male 
still remains unknown.

Islands. Identified by Sars from the first three of these Albatross 
stations and from 10 Monaco stations and found in limited numbers in 
the Carnegie plankton.
