Entomostraca from the Arctic Seas. 351 
Harpacticus chelifer (Miiller). 
One or two specimens of this Copepod were noticed in a 
tow-net gathering collected in Kval Sound on July 24th; 
while several of the variety arcticus, Poppe *, were obtained 
amongst bottom-material chiefly collected on the west side of 
Bear Island on July 3rd, near Hope Island on July 7th, and 
in lat. 76° 33! N., long. 33° 43! E., on July 13th. 
Zaus spinatus, Goodsir. 
Specimens of Zaus spinatus were not uncommon in one or 
two bottom-gatherings collected near Kolguev Island and 
between there and Novaya Zemlya in June. 
Zaus Goodsiri, Brady. 
A specimen of this fine species, measuring 1-4 mm. (5 of 
an inch), was obtained in a sample of bottom-material trom 
100 fathoms collected in lat. 76° 24’ N., long. 33° 43’ E., 
on July 13th. 
Zaus Aurelit, Poppe. (Pl. IV. figs. 7-12.) 
1884. Zaus Aurel, Poppe, Ueber die von den Herren Dr, Arthur u. 
Aurel Krause im nordl. Stillen Ocean u. Behrings-Meer gesammelten

p- 286, Taf. xx. figs. 7-9, Taf. xxi. figs. 5-15. 
Specimens of a Copepod which appear to us to belong to 
Poppe’s Zaus Aurelit were obtained in a bottom-gathering 
from 20 fathoms between Kolguev Island and Novaya 
Zemlya collected on June 16th. In the adult female, of 
which we give a drawing (see Pl. IV. fig. 7) the cephalic and 
thoracic segments are scarcely so broad as they are shown to 
be in Dr. 8. A. Poppe’s figure, but a slight amount of extra 
pressure on the cover-glass under which the specimen was 
placed might be sufficient to account for this. The Kolguev 
specimens appear also to be rather smaller than those from 
the North Pacific and Behring’s Sea; but, as will be seen by 
* Mr. T. Scott, in his “ Report on Franz-Josef Land Crustacea ” (Journ. 
Linn. Soc., Zool. vol. xxvii.), describes and figures a variety of H. chelifer 
under the name of var. arcticus. At this time he was unaware of the 
fact that Dr. S. A. Poppe had in 1884 published a paper on some North 
Pacific and Behring’s Sea Copepods. In this paper Dr. Poppe has also 
described a var. arcticus of the same species, and it is interesting to 
note that the variety described by T. Scott is practically identical with 
that described by Dr. Poppe. Dr. Poppe’s varietal name hus, of course, 
clear priority over Mr. Scott’s, and must therefore be adopted.
