has also been reported from the Pacific by Sewell (1932, p. 336).

Stations 2195 ; 4598 ; 4640; 4655 ; 4664; 4671; 4679; 4707; 4721; 4730; 
4743; 5105; 5190; Port Binanga, Luzon, Philippine Islands. Dana’s 
original specimens came mostly from the southern Atlantic, with a 
few from the China Sea. He gave the color as “smoky with black 
bands about the cephalothorax; the extremities of the antennae and 
some of the natatory legs black.” There are still traces of this colora- 
tion in the Albatross specimens after 30 years’ preservation. The 
species is present in all the plankton lists, and abundant in the Siboga 
plankton, where it is recorded from 52 stations.

abundant in the Szboga and Monaco lists.

Stations 4714; 4724. Two females were obtained at station 4714 
near the Galapagos Islands in a surface tow. Sars identified them as 
belonging to this species and so recorded them, but somewhere during 
the journeying back and forth the specimens themselves have been
