Condylanthus aucklandicus n. sp. 
Di agn osi s. Body conical. Cuticle of the scapus thin, easily 
deciduous. Sphincter weak, diffuse close to the tentacles. Tentacles 
24 hexamerously arranged, conical, short. Longitudinal muscles of 
the tentacles considerably stronger on the inside than on the out- 
side. Actinopharynx long with indistinct siphonoplyphes. Pairs of me- 
senteries at least in four cycles, the last cycles very weak, present only 
in the undermost part of the body. Muscle pennons in the upper 
part of the mesenteries, strong, richly ramificated, in the under part 
considerably weaker. Parietal part of the longitudinal muscles and 
the parietobasilar muscles very strong and richly ramificated in the 
under part of the mesenteries, weak in the upper. Mesenteries of 
the second order recalling the parietal part of those of the first. Mes¬ 
enteries of the third and fourth orders very small, only in the 
proximal part. Nematocysts of the capitulum 1 9 — 22 x almost 2—2/^

pharynx about 24 X 4,5 /r, the last broader at the basal end, spiro-

Exterior asp eet. As to the exterior, the single specimen 
(textfig. 8) was not well preserved, the column very contracted and 
very folded, the actinopharynx for a great part evaginated. The 
pedal disc is broader than the upper part of the column and fur- 
nished with a cuticle. The column is divisible in scapus and capi¬ 
tulum, the former is rather thick and provided 
with a thin, easily deciduous, dirty gray cuticle. 
The thin capitulum is rather long. The ten¬ 
tacles are 24, hexamerously arranged in three 
close standing cycles. In contracted State they 
. .. are conical, very short and thick. The almost 
wholly evaginated actinopharynx was provided 
' " with 12 longitudinal ridges. If siphonoglyphes
