The mesogloea of the scapus is thicker than the ectoderm and 
fibrillous with few cells. The nematocysts of the capitulum were 
small as usually in Edwardsia, their size was 10 — 15 x 1,5 (i. 
Concerning the nematocysts of the tentacles and actinopharynx 
compare diagnosis! The ectoderm of the actinopharynx was very 
high in the ridges, rather thin to thin in the furrows. The cilia 
of the siphonoglyphe was longer than in the other part of the 
actinopharynx. 
The mesenteries show an arrangement equal to that in E. cla- 
paredii. The micromesenteries were very weak. The pennons of 
the stronger mesenteries were well developed as were also the 
parietal muscles. The sections of a pennon and a parietal muscle 
in the reproductive region of a specimen from Auckland Island 
(textfigs. 2, 3) and of the specimen from Slipper Island (textfigs. 4, 5) 
show good agreement. The more curved pennon in the latter spec¬ 
imen is of no importance as due to a stronger contraction. I have 
found sections of about equal appearence also in the former spec¬ 
imen. Concerning the folds etc. compare the diagnosis. One specimen 
was a male, the other a female. 
Remarks. It is impossible to decide, without an examination 
of the nematocysts in the nemathybomes, whether tricolor {elegans) 
and neozelanica are two distinet species or not. To my mind they 
probably belong together.

small. Muscle pennons only on the five first couples, the sixth 
couple agreeing with the weaker mesenteries (4 single mesen¬ 
teries of the second cycle in the four lateral and ventrolateral exo- 
coels (always?). Muscle pennons not extended but more concentrated 
with high and ramificated folds. Parietal muscles of the perfeet 
mesenteries with few palisade-like folds, imperfeet mesenteries 
developed about as the parietal part of the perfeet, not forming 
pennons. Nematocysts of the column 12 x l those of the ten¬
