COPEPODS GATHERED BY ALBATROSS—WILSON 201 
mined by Sars, failed of record in the Wilson manuscript. Their 
identification has been verified by Mrs. Mildred S. Wilson (vide foot- 
note 1, p. vii). The taking of some 150 specimens, practically all 
females, in a dredge haul made in 20-25 meters in West Cumberland 
Bay, South Georgia, is reported by Pesta (1930, p. 101) —W. L. S.]

DYSGAMUS ARIOMMUS Wilson 
Dysgamus ariommus WIison, Proc. U. 8S, Nat. Mus., vol. 31, p. 713, pl. 20, figs. 
62-70, 1907. 
Stations 3829; 5228. Two males were taken in the tow at this 
second station south of Romblon Island in the Philippines and a third 
at the first station south of the Hawaiian Islands, all three swimming 
freely. The species does not appear in any of the lists, and these are 
the first specimens to be obtained since the original discovery. In 
discussing the commensal and parasitic copepods of the Siboga plank- 
ton, Dr. Leigh-Sharpe (1934, p. 28) described seven specimens that 
he referred to Brady’s species murrayi, which Brady had placed in 
the genus Vogagus. Brady’s description in the Challenger report 
was very meager, and in his single figure the first two pairs of legs 
were entirely lacking. Dr. Leigh-Sharpe’s excellent figures supplied 
these and many other missing details, but he made the present species 
ariommus a synonym of murrayi, which his own figures proved to be 
impossible. In murrayi the endopods of the first three pairs of legs 
are 1-segmented, the genital segment has a pair of large leg rudiments, 
and in his own words, “there are two furcae one behind the other.” 
In ariommus the endopods of all four pairs of legs are 2-segmented, 
there are no leg rudiments on the genital segment, and the furca is 
certainly single. It may be added that none of the other appendages 
show correspondence in detail and such a total lack of accord in spe- 
cific characters effectively prohibits any idea of synonymy suggested 
by general appearance.

Stations 3683; 3829; 4010; H. 8789. About 20 males were taken 
in a surface tow at station H. 3789 north of the Marquesas Islands 
on September 9, 1899. Single males were obtained at each of 
the other stations except station 3683, at which 3 were taken. 
Male.—Carapace 55 percent of the entire length and five-sixths as 
wide as long, with the dorsal pattern of grooves shown in figure 51. 
Frontal plates prominent and separated by a narrow median incision; 
lateral lobes with their bluntly rounded ends turned inward, just
