Di agn osi s. Sphincter distinet, rather long. About 40 radial 
rows of endocoel-tentacles, each row containing 2—4 tentacles. 
About 40 (35 —41) pairs of mesenteries. Not half the mesenteries 
perfeet. 1 —3 pairs of directives. Specific nematocysts with very 
coiled thread in the filaments 72—88 x 26—29 y, in the caput 
of the tentacles 65—71 x 13—17 in the actinopharynx 31-—36 
X 9 — 10 y, in the column 31 — 41 x 7 Spirocyst-like cnidae 
with visible basal part to the spiral thread in the caput of the ten¬ 
tacles 48—61 X 4 , 5—5 
Colour very variable, compare Farquhar and Stuckey. 
Dimensions in contracted State about 1 cm high and 0,8 cm 
broad. An extended oral disc was 1,2 cm in preserved State. 
Occurrence. Slipper Islands. Coast, at low-water 20.12.1914. 
Several specimens. 
In the neighbourhood of Wellington (teste Farquhar and 
Stuckey). 
Exterior aspect. The exterior of this species agrees with 
other Corynactis-S'^QCXQS. A good description is given by Farquhar. 
The rows of endocoel-tentacles were about 40. The arrangement 
rather well agrees with that of Corynactis globulifera (Carlgren 
1900, p. 21 ). In a specimen with well extended oral disc the ar¬ 
rangement of the endocoel-tentacles was as follows (the figures indi- 
cate the number of tentacles in the rows) 3, 2, 4, 3, 4, 3, 3, 4, 
3, 4, 4, 3, 2, 4, 3, 3, 4, 3, 4, 3, 4, 3, 4, 3, 3, 3, 4, 2, 3, 3, 
4, 2 ,' 3, 2, 4, 3, 3, 2, 3, 2 = 40 rays. Between the endocoel- 
rows there issues one tentacle from each exocoel. The exocoel- 
tentacles are larger than the endocoel-tentacles and are situated 
inside the outmost endocoel-tentacles. Of these latter the innermost 
are the smaller, the outmost the larger. The actinopharynx is provided 
with numerous longitudinal ridges and furrows. There are no distinet 
siphonoglyphes.
