Postscript. 
After describing the above named Actiniaria I have had the op- 
portunity of studying a small collection of Actiniaria made by Sten 
Wall in 1924 at the Stewart and Campbell Islands. From Stewart 
Island, Paterson Inlet, the occurrence of Åctinia tenebrosa and Crico- 
phorus nutrix is to be noted, from Campbell Island, Perseverance Bay, 
numerous specimens of Parantheopsis cruentata and the species here 
called Epiactismortenseni. As to the latter species I have stated (p. 217) 
that the “column is, as far I can see, without sucking warts“. In 
several of Wallin’s specimens, which were mostly not so much 
contracted as those collected by Mortensen, there are, however, 
distinet verrucae arranged in longitudinal rows, but there are not 
many verrucae in each row and they are the most distinet in the 
middle of the column. A doser examination of these verrucae, 
which are invaginated, shows that their ectoderm is structured as 
that of the Urticina-werrucae. There is, however, here no evagination 
from the endoderm into the verrucae, though the mesogloea is thinner 
than in other parts of the column. Such warts I have observed also 
in other Actiniaria, for inst. in the genus Sagartia. No doubt the 
specimens collected by Mortensen and Wallin belong to one 
and the same species. Both agree in the characteristic arrange¬ 
ment of mesenteries, in the presence of a parasitic Trematod in 
the sphineter and in other characters. Also the size of the nemato- 
cysts shows good agreement, only the nematocysts with perspieuous 
basal part to the spiral thread in the actinopharynx were somewhat 
longer in Wallin’s specimens; further the breadth of the nemato¬ 
cysts was a little larger, possibly caused by a difference in the pre- 
servation. The colour was still distinet in several of Wallin’s spec¬ 
imens which had been preserved in formaline-alcohol. The column 
was red-brown, crimson or orange with more or less irregular ver- 
tical pale (white?) lines and pale verrucae, the tentacles greenish, 
sometimes with reddish tips (possibly banded), the oral disc greenish, 
the actinopharynx and inner parts reddish. On account of the pre¬ 
sence of verrucae on the column this species must be named Bu- 
nodaetis {Qribrina) morienseni.
