the species very common. 
Pseudocalanus elongatus, Boeck. 
This species occurred in one or two gatherings collected 
between Koleuev and the neighbouring shores of Novaya 
Zemlya in June; and in July in the vicinity of Hope 
Island, in various parts of the Barents Sea, and in Kval 
Sound, but nowhere very common.

* Several specimens of this moderately distinct species were 
obtained in a gathering collected near the shore on the east 
side of Koleuev Island on June 12th. A number of other 
species, such as Ovthona helgolandica, Jonesiella spinulosa, 
Platychelipus littoralis, and Idya furcata, were also observed. 
Prot. G. O. Sars states that Pseudocalanus pygmeus ‘ oc- 
curred in considerable numbers in samples taken north of 
the New Siberian Islands in October 1893,” and adds that 
no male specimen was found. With regard to the apparent 
absence of male specimens noted by Professor Sars, it may 
be of interest to remark that we also failed to obtain a single 
male amongst the specimens collected by Mr. Bruce. This 
absence of male specimens made us at first somewhat doubt- 
ful concerning the species to which the specimens observed 
by us should be ascribed, but after careful examination of 
them we are satisfied that they are identical with the Psewdo- 
calanus pygmeus of G. O. Sars. 
Fam. Centropagide. 
Centropages hamatus (Lilljeborg). 
The only gathering in which this species was observed 
was one collected in Kval Sound on the 24th of July—it 
was a tow-net gathering trom near the surface of the water. 
Only one or two specimens of the Centropages were observed. 
Temora longicornis (Miiller). 
This species, which is sometimes exceedingly common 
in the British seas, occurred in the same gathering with the
