last only in the uppermost part of the actinopharynx, and provided 
with filaments. The mesenteries of the first and second order were 
fertile. The species is dioecious. The pennons are diffuse, their 
folds not high but often richly ramificated, the pennons are broad 
on the mesenteries of the first order (compare the fig. 2, PI. 17, 
Stuckey 1909a). The parietobasilar muscles are broad and form 
a distinet fold inwards, their muscle lamellae are low. The oral 
stomata are large, the marginal stomata smaller. The mesogloea 
in the region of the ciliated tract contains numerous cells. 
Anthopleura sp. ? 
Di agnosis. Pedal disc broad. Column in contracted State 
conical, in the upper part with distinet Urtidna-vQrrucac corre- 
sponding to the endocoels. Fossa distinet. Sphineter as in aiireo- 
radiata. Tentacles from 38— 54. 2 distinet gonidial tubercles and 
siphonoglyphes. Mesenteries about 24 pairs one half perfeet. Pen¬ 
nons of the mesenteries strong with high and ramificated folds 
(stronger than in aureo-radiata). Parietobasilar muscles strong, form- 
ing a distinet fold. Nematocysts of the column 12 — 17 x( 1 ) 1 , 5—2 
those of the tentacles 17— 22 x 1,5 those of the marginal sphae- 
rules partly 29—37X3,5 -4,5 (5) p, partly (22) 25— 31 x(2)2,5— 
3,5 p (probably transition stages between the two kinds present), 
those of the actinopharynx 22—24X2 /i. Spirocysts of the tent¬ 
acles 10X1—23X2 , 5 /^'. Endoderm with Zooxanthellae.

Dimensions. Largest specimen from Paterson Inlet: breadth 
of the pedal disc 0,8 cm, height 0,7 cm. 
Occurrence. Stewart Island, Paterson Inlet; littoral, under 
stones 18.11.1914 numerous specimens. Stewart Island, Port Pega¬ 
sus; littoral, under stones 22.11.1914. 2 specimens. 
I have not given a name to this species, because the spec¬ 
imens were not sexually ripe and it is possible that it is a young 
form of Anthopleura inconspicua (Phymactis inconspicua Hutton, Bu¬ 
nodes inconspicua Stuckey) or of A. rosea {Bunodes rosea Stuckey 
and Walton). The Urticina-VQTvwcao. were mostly distinet, in some 
specimens they had stones attached to them. The tentacles were 
38, 38; 48, 54 in 4 examined specimens, in the last specimen 
(from Port Pegasus) the tentacles were 24 on one side, 30 on the
