COPEPODS GATHERED BY ALBATROSS—WILSON 207 
EUAUGAPTILUS PALUMBOI (Giesbrecht) 
Augaptilus palumbii GiEsBRECHT, Atti Accad. Lincei, Rome, ser. 4, vol. 5, sem. 1, 
p. 813, 1889; Fauna und Flora des Golfes von Neapel, monogr. 19, pp. 400, 
413, pl. 27, fig. 32; pl. 28, figs. 3, 15, 17; pl. 39, figs. 39, 50, 1892. 
Stations 9; 4652; 4673; 4687; 4705; 4708; 4722; 4730. Giesbrecht’s 
type specimens came from the eastern Pacific southwest of the Gala- 
pagos Islands. Sars identified the species from 3 Monaco and from 
these eight Albatross stations; A. Scott found it at six Siboga stations. 
It does not appear in the other lists, but Wolfenden (1911, p. 340) has 
reported it as Augaptilus palumbot from the Antarctic, and so it is 
well distributed, although the number of specimens obtained is quite 
small. 
EUAUGAPTILUS RIGIDUS (Sars)

Augaptilus rigidus Sars, Bull. Inst. Océanogr. Monaco, No. 101, p. 21, 1907. 
Euaugaptilus rigidus Sags, Rés. camp. sci. Albert de Monaco, No. 69, p. 298, pl. 
103, 1925. 
Station 4687. Two females were identified by Sars from this A/- 
batross station and a single female from the Monaco plankton. The 
latter specimen upon which the species was founded had lost most of 
the setae upon its caudal rami, and so his excellent description and 
figures were lacking in this detail. He made pencil sketches of these 
perfect Albatross specimens, and they are reproduced here to supple- 
ment his Monaco figures. 
EUAUGAPTILUS SQUAMATUS (Giesbrecht) 
Augaptilus squamatus GIEsBRECHT, Atti Accad. Lincei, Rome, ser. 4, vol. 5, sem. 
1, p. 814, 1889; Fauna und Flora des Golfes von Neapel, monogr, 19, pp. 
400, 413, pl. 28, figs. 1, 12, 18, 22, 25, 34; pl. 39, fig. 88, 1892. 
Stations 4607 ; 4652; 4659 ; 4667; 4671; 4679 ; 4681; 4687; 4700; 4707; 
4711; 4717; 4719; 4721; 4722; 4734; 5185. Giesbrecht’s type speci- 
mens came from north of the Marshall Islands in the tropical Pacific, 
and these Albatross stations are also in the Pacific. The Monaco sta- 
tions from which it was identified by Sars, on the contrary, were all 
in the northern Atlantic.
