pl. 6, figs. 22-26, 1849. 
Stations 3696; 4678; 5340. Well distributed at nearly 150 stations 
in the Monaco plankton but found only once in the Carnegie plankton 
and not at all in the others. Although it was confined to these three 
stations in the Albatross plankton, over 75 specimens were obtained in 
a surface tow at the first of the three, located off Honshu, Japan.

The list shows that this was one of the most widely distributed species 
of the genus in the Albatross plankton. It was second in abundance 
in the Monaco plankton, third in the Carnegie plankton, but did not 
appear at allin the Wilkes, Challenger, and Siboga planktons. Brady 
recorded in the Challenger plankton specimens that he referred te 
this species, but later they were given a new name, Centropages bradyi, 
by Wheeler (1901, p. 174). 
Genus CEPHALOPHANES Sars, 1907 
CEPHALOPHANES REFULGENS Sars 
Cephalophanes refulgens Sars, Bull. Inst. Océanogr. Monaco, No. 101, p. 15, 1907 ; 
Rés. camp. sci. Albert de Monaco, No. 69, p. 154, pl. 48, 1925. 
Stations 2; 62; 4681; 4683; 4719; 4730; 4738; 4952. Originally 
established by Sars upon female specimens from 19 Monaco stations 
in the temperate Atlantic, it does not appear in any of the other 
planktons. The male was described and figured by Steuer (1926, 
p. 182) from the southern Atlantic; the species was also recorded 
by Farran (1908, p. 49) from the Irish Atlantic Slope. Except for 
the first and last stations, these Albatross specimens were identified 
by Sars and are a first record from the Pacific Ocean.
