the tip of the hand. The endopod of the second legs has an elongate 
acuminate spine at the distal corner of the outer margin of the second 
segment, which reaches far beyond the tip of the third segment. The 
fifth legs are much reduced in size, the inner expansion of the basal 
segment has entirely disappeared, and the outer process is represented 
by a short spine. The terminal segment is very small and armed with 
four setae. A sixth pair of legs is indicated at the posterior corners 
of the genital segment by one larger spine and several smaller ones. 
Neotypes.—U.S.N.M. No. 74158, Rat Islands, western Aleutian Is- 
lands. 
Remarks.—As noted by Smirnov, the second legs of the male resemble 
those of the genus Harpacticus more than those of Tigriopus. But in 
other respects the male and in all details the female correspond to the 
present genus. 
Genus TORTANUS Giesbrecht, 1898 
TORTANUS BARBATUS (Brady) 
PLATE 36, Figure 560 
Corynura barbata Brapy, Voyage of H. M. S. Challenger, Zool., vol. 8, pt. 23, Cope- 
poda, p. 71, pl. 31, figs. 10-12, 1883. 
Stations 5175; 5176. Established by Brady upon a single female 
from Zebu Harbor, Philippine Islands and three females recorded by 
Scott in the Siboga plankton from Manipa Strait just south of the Phil- 
ippines. A male was added by Friichtl (1923, p. 456) from the Aru 
Islands, and the species was reported from the Bay of Bengal by Sewell 
(1912, p. 3877). As can be seen in the figure, the fifth legs of the female 
are very asymmetrical, the left one with a tuft of curved claws at the 
center of the inner margin. 
TORTANUS DISCAUDATUS (Thompson and Scott) 
Corynura discaudata THompson and Scott, Trans. Liverpool Biol. Soc., vol. 12 
(1898), p. 80, pl. 6, figs. 1-11; pl. 7, figs. 1, 2, 1897. 
Stations 4756; 4758. Identified by Sars from these Albatross and 
from two Monaco stations and is not found in the other planktons. 
It has generally been considered a littoral rather than a pelagic species, 
as it is sometimes found in considerable numbers close to shore. The 
Albatross specimens were taken in vertical hauls to the surface from 
75 and 300 fathoms respectively. 
TORTANUS FORCIPATUS (Giesbrecht) 
* Corynura forcipata GirsBREcHT, Atti Accad. Lincei, Rome, ser. 4, vol. 5, sem. 2, 
p. 26, 1889; Fauna und Flora des Golfes von Neapel, monogr. 19, pp. 525, 
530, pl. 31, figs. 2, 3, 5, 7, 9, 10, 12, 15; pl. 42, figs. 34, 37, 1892.
