Gen. Synphellia n. gen. 
Di agn osi s. Pedal disc large, considerably broader than the 
oral disc. Column divisible into scapus and capitulum, the former 
with Halcampa-paplWae. Sphincter strong and long, mesogloeal. 
Tentacles considerably fewer than the mesenteries, the inner longer 
than the outer. Longitudinal muscles of the tentacles and radial 
muscles of the oral disc ectodermal. 2 siphonoglyphes. Mesenteries 
more numerous in the basal part than in the proximal, 6 pairs or 
a few more perfect. Perfect mesenteries with strong, high, diffuse 
to almost circumscript pennons, imperfect mesenteries without pen¬ 
nens. Filaments on the perfect as well as on the stronger imper¬ 
fect mesenteries. Parietobasilar muscles in the perfect mesenteries 
rather well developed. Acontia with nematocysts of ordinary length. 
Distribution of the reproductive organs? (Perfect mesenteries pro- 
bably fertile ?). 
As the species described below is not sexually ripe, it is very diffi- 
cult to decide if we have to do with a new genus or not, as also whe- 
ther the genus really belongs to the Phelliidae. It is certainly differ- 
ent from Phellia and Isophellia on account of the more numerous me¬ 
senteries in the proximal than in the distal part, but recalls in that 
respect Paraphellia (compare Haddon’s and Stephenson’s de- 
scription of that genus). Possibly it will appear in the future that 
Synphellia and Paraphellia are synonyms, and in that case Syn¬ 
phellia may be dropped. 
Synphellia aucklandica n. sp. 
Di agn o si s. Cuticle of the papillae strong. Sphincter not 
stratified, not occupying the whole breadlh of the mesogloea, with 
small but numerous rather close meshes. Tentacles about 48. Pairs 
of mesenteries in the upper part about 24. 6 or a few more per¬ 
fect. Nematocysts of the capitulum 14—18X2 y, those of the tent¬ 
acles 14 — 19 X 1,5 —almost 2 y, (those of the actinopharynx 13 —14 
X2—2,5 ,(/?), those of the acontia 29—41X2,5—4(4,5) y, spiro- 
cysts of the tentacles 14 x about 1—29X3 y. 
Colour in alcohol. Plaleampa-papiWae brown, other parts pale 
yellow.
