Genus DACTYLOPUSIA Norman, 1903 
DACTYLOPUSIA VULGARIS Sars 
Dactylopusia vulgaris Sars, Crustacea of Norway, vol. 5, p. 128, pl. 79, fig. 1, 
1905. 
Two females of this species were found in a small vial containing 
a printed Albatross label, which, unfortunately, carried no other data. 
This is a common and widely distributed harpacticoid, though not in 
any of the plankton lists, and might well be included in the plankton 
picked up at any of the anchorages. 
Genus DISSETA Giesbrecht, 1889 
DISSETA MAXIMA Esterly 
Disseta mavima Esterty, Univ. California Publ. Zool., vol. 6, No. 14, p. 330, 
pl. 29, figs. 54, 58; pl. 30, fig. 79, 1911. 
Stations 5320; 5437. Established by Esterly upon a few female 
specimens from off the coast of southern California and not found 
in any of the plankton lists. The male still remains unknown, and 
the species is very limited in its distribution.

pl. 29, figs. 2, 8, 14, 19, 23-25, 27; pl. 38, fig. 44, 1892. 
Stations 2; 13; 18; 4652; 4661; 4663; 4665; 4667; 4669; 4673; 4676; 
4679; 4687; 4705; 4707; 4711; 4717; 4719; 4722; 4730; 4793; 5129; 
5185; 5225; 5231; 5320. Established by Giesbrecht upon a single 
female from the tropical Pacific, the male was afterward described 
and figured by A. Scott in the Siboga plankton. Twenty-five speci- 
mens were identified by Sars from the first 19 of these Albatross sta- 
tions; earlier he reported the species from 54 stations in the Monaco 
plankton. Neither Scott nor Sars noted the tripartite spine on the 
second exopod segment of the fifth leg in the female. This was figured 
by Giesbrecht and noted by Sewell (1932, p. 309). As found in these 
Albatross specimens, it is dark in color and highly chitinized and 
stands up at right angles to the surface of the leg, making a good 
identifying character.
