Calanus finmarchicus Sars, 1901, Vol. IV, p. 9, plates I, I, I. 
A few examples, which are indistinguishable from this northern species, except 
in point of size, were found in gatherings taken by the tow-net off “ Maria Tsland, 
Tasmania.” Southern specimens (females only) are a little over 3 mm. in length, the 
normal length of the Norwegian animal, according to Professor G. O. Sars, being 4 mm., 
and of the largest Arctic specimens 5 mm. It is quite likely, however, that many other 
examples of the species may have been overlooked, it being impossible accurately to 
separate the various species without careful examination of each individual.

This is by much the most abundant of all the Copepoda in the collections 
submitted to me. Scarcely any of the tubes were without examples of it, and in very 
many it constituted the greater part of the gathering. The following list indicates 
the localities in which 1 have notes of its occurrence.
