Hariot is certainly right in separating this plant from the last. De Тот 
places it with a query under Rhodymenia, but Hariot distinctly states that the 
cystocarp is that of Callophyllis.

C. antarctica is the only species of the genus known from the Antarctic 
or Subantarctic regions. Hariot’s description is somewhat brief, but, as the 
Falkland Islands specimens agree well with it, there seems no reason to 
regard them as distinct. The plant was found by both the French expe- 
ditions, and on each occasion off Graham Land ; the present record, therefore, 
gives it extension of range. 
The alga is certainly a Callymenia, ripe cystocarps showing the usual 
structure of the genus. The fronds in the present gathering are ovate, 
tapering gradually to the base or more or less truncate, and the tufted habit 
noted by Hariot is well marked.

С. Opuntia is probably more widely spread than hitherto supposed. Jt is an 
addition to the Falkland Islands list, but was recorded by Hariot from Fuegia.
