COPEPODS GATHERED BY ALBATROSS—WILSON 231 
GAETANUS INERMIS Sars 
Gaetanus inermis Sars, Bull. Mus. Océanogr. Monaco, No. 26, p. 12, 1905a; Rés. 
camp. sci. Albert de Monaco, No. 69, p. 64, pl. 19, figs. 8-5, 1925. 
Station 4664. A single female was identified by Sars from this sta- 
tion off the Peruvian coast in a vertical tow from a depth of 300 
fathoms. The original specimens came from the temperate Atlantic, 
and the only record since then is by Rose in the Monaco plankton from 
another station in the temperate Atlantic. Consequently, this Alba- 
tross female is the first specimen to be obtained from the Pacific. 
GAETANUS KRUPPII Giesbrecht 
Gaetanus kruppii GIEsBRECHT, Mittheil. Zool. Stat. Neapel, vol. 16, p. 202, pl. 7, 
fig. 8; pl. 8, fig. 29, 19038. 
Stations 2; 2195; 3799; 4637; 4642; 4650; 4663-4665; 4667; 4669; 
4679; 4681; 4687; 4707; 4711; 4715-4717; 4719; 4722; 4793; 5120; 
5185; 5287; H38789. Identified by Sars from 18 of these Albatross 
stations and from 68 Monaco stations and found also in the Szboga and 
Carnegie planktons. Sars (Monaco plankton) designated it as one 
of the most abundant bathypelagic copepods, and this statement re- 
ceives negative confirmation from the small number of specimens in 
the Albatross plankton, which were mostly taken in surface tows. 
GAETANUS LATIFRONS Sars 
Gaetanus latifrons Sars, Bull. Mus. Océanogr. Monaco, No. 26, p. 11, 1905a; Rés. 
camp. sci. Albert de Monaco, No. 69, p. 57, pl. 17, figs. 7-9, 1925. 
Stations 3799 ; 4663 ; 4683; 4685 ; 4707 ; 5120; 5185; 5227; 5287; 5437. 
This species was found at 1 Siboga, 1 Carnegie, and 52 Monaco sta- 
tions and is more abundant in the deeper tows. 
GAETANUS MICROCANTHUS [Sars MS.] Wilson, new species 
PLATE 11, Ficures 114-116; Prats 19, Ficure 246 
Stations 4664; 4667; 4669; 4679; 4681; 4719; 4722. Fifteen speci- 
mens, including both sexes, were obtained from these stations off the 
Peruvian coast and between Easter Island and the Galapagos Islands. 
Femaie.—Metasome short and thick-set, considerably narrowed at 
both ends; the forehead with a small and slender spine turned down- 
ward. The posterior corners of the last segment are broadly rounded, 
with a minute spine pointing backward. The urosome is less than a 
third as long as the metasome and is 4-segmented, the segments dimin- 
ishing in length backward. The genital segment is as wide as long, 
the sides nearly parallel, the ventral surface with a subrectangular 
prominence. The three abdominal segments increase slightly in width 
distally, and the posterior margin of the anal segment is incised at
