COPEPODA—BRADY. 29 
Most of the gatherings contained specimens belonging to the genus Oithona, but 
I am unable certainly to identify them except in the cases mentioned above. Most of 
the specimens may, I think, be referred to O. frigida. 
Family LONGIPEDIIDA. 
Genus LONGIPEDIA Claus, 1863. 
Lonatrepra Scorrr G. O. Sars. 
Longipedie Scotti, G. O. Sars, 1903, vol. v, p. 11, Plate 5. 
A single specimen agreeing in every respect with Professor Sars’ description and 
figures of L. Scotti occurred in the tow-net gathering from Station 15. 
Family Korrnosomip. 
Genus MicROSETELLA Brady and Robertson, 1873. 
MIcROSETELLA ATLANTICA B. & R. 
(Plate XIII, figs. 9-12.) 
Microsetella atlantica, B. & R., 1878, p. 180, Plate IX, figs. 11-16. 
Specimens which are indistinguishable from the typical M. atlantica were found 
among the tow-net proceeds of Stations 1, 7 and 8. 
M. atlantica, however, is considered by Professor Sars to be identical with 
Setella norvegica Boeck, and the earlier specific name has therefore been adopted by 
him. If this view is accepted the species must of course be named Microsetella norvegica. 
I give in Plate 13 figures of some details from Antarctic specimens, of which females 
only have been seen—length 0-47 mm. Length stated by Professor Sars, 0:46. Length 
originally given for M. atlantica, gg of an inch. 
Family Harpacricipé&. 
Genus Harpacticus Milne-Edwards, 1838. 
HLARPACTICUS PULVINATUS Brady. 
Harpacticus pulvinatus Brady, 1910, p. 550, fig. 39. 
A single specimen which seems to be referable to this species was found in the 
tow-net gathering from Station 5, but was so profusely infested with an infusorian 
parasite that it was impossible so make out accurately all the structural details. 
Family THALESTRIDA. 
Genus Dacrytopusta Norman, 1903. 
DACTYLOPUSIA BREVICORNIS (Claus). 
One specimen of this well-known northern species occurred in the tow-netting 
from Station 1,-and a few in that from Station 7.
