Station 1. 
It may be doubted whether the specimen was growing at the 
depth at which the trawl was open, 54-55 fathoms. Only a fragment 
was brought up by the trawl, and, as it has no air-cells, it is denser 
than water. D’Urvillea, though sometimes detached from rocks and 
found floating, is a plant of the intertidal region. Taking these facts 
into consideration, and the fact that the specimen is considerably 
decomposed, it seems more reasonable to imagine that this is a piece 
which has drifted off shore, and perhaps been dropped from a larger 
floating mass above the spot where it was picked up by the trawl. 
The absence of air-cells probably shows that it is a fragment broken 
off from the region of the stem. 
(If the rules of the Vienna Congress are adopted for cryptogams, 
the specific name will have to be changed to antarctica, as it was 
originally described by Chamisso as Fucus antarcticus.)

Stations 2, 6. 
The specimen from Station 2 is without bladders, though otherwise 
well developed. This is a very interesting modification, probably 
due to the increased pressure at the depth (32-41 fathoms) at which 
the plant was growing. I do not remember to have seen a similar 
modification elsewhere recorded.
