similar capsules, which however are narrower in the basal end than 
in the distal, their basal part to the spiral thread is perspicuous but 
the spiral thread itself is very indistinct. In the column their size 
was partly 14—19 x 3 /n, partly 19—29 x 4,5—5 fiy in the fil¬ 
ament 34—43 X 10—11 In difFerent parts of the ectoderm 
there were also opaque, often irregular developing-stages of stinging 
capsules. 
Fam. Edwardsiidae. 
As I have already pointed out (Carigren 1921, p. 25) I cannot 
accept the supposition of Bo urne (Journ. Linn. Soc. 32 Zool. 1916, 
p. 513) and Stephenson (compare Stephenson 1921, p. 538, 
559) that the Edwardsiids “must rank as a distinet group equal to 
that containing the Zoanthids“ and the Dodecaetiniaria (Actiniaria 
and Madreporaria). The Edwardsiids certainly belong to the group 
Athenaria among the Actiniaria.

Di agn osis. Physa well developed. Scapus with a thin peri- 
derm and very numerous, small scattered nemathybomes occupying 
the whole surface. Nematocysts of the nemathybomes partly 41—56 
X 5 , 5 —. 4,5 partly 34—41 x almost 2 the latter strongly dimin- 
ishing towards the distal end. Especially upper part of scapus and 
capitulum polygonal. Tentacles 16 (16—24 in neozelanica). Nemato¬ 
cysts of the capitulum 10—15 x 1 those of the tentacles 22—24 
X almost 2 and of the actinopharynx partly 20—24 x l — 1,5 
partly 31—36 2— 2,5 Longitudinal muse le pennons of the 
mesenteries in the reproductive region well developed with about 
20—30 mostly high folds especially ramificated in the outermost 
part. Outer lamellar part of the mesenteries attached close by the 
outside of the pennons. Parietal muscles strong. Main lamella of the 
mesogloea in the region of the parietal muscles thick. Distribution 
of the parietal muscles on the column considerable.
