This species occurs rather plentifully in most of the tow-net gatherings—notably 
from Stations 7 and 9, but it certainly occurs not uncommonly amongst the crowd of 
minute species from other localities. The specimens here noted agree in all respects 
with those described and figured by Dr. Giesbrecht, except perhaps as to the endopodites 
of the swimming feet which are represented by that author as having profusely setiferous 
margins. None of those examined by me seem to bear any marginal sete whatever. 
SUPPLEMENTARY. 
MICROCHELONIA GLACIALIS nov. 
(Plate XV, figs. 1-6.) 
It seems desirable to give some account of a very remarkable minute species of 
which one specimen only could be found in a gathering from Macquarie Island, marked 
C.17. I give outline drawings of the entire animal, and of such of the appendages as 
could be seen after dissection. But the creature was so excessively tough and pachy- 
dermatous, and likewise so opaque, that I found it impossible to do more than tear it 
roughly to pieces. It would seem, however, to form the type of an entirely new division 
of the Copepoda, and future collectors in the Macquarie area would do well to look out 
for it. My impression is that it, and probably many other interesting forms would 
probably be found by washing the fronds and roots of sea-weeds—especially Laminaria.
