Diagnosis : Colony erect, flabellate, branched 
in one plane; branching with frequent anasto- 
mosis forming a network with elongate rec- 
tangular meshes. Largest branches and the end 
twigs round in cross section, the intermediate 
ones flattened at right angles to the plane of 
branching. Twigs 1.5 to 2.0 mm. in diameter, 
flat branches about 7.0 by 10.0 mm. in diam- 
eter, large main branches 30 mm. and probably 
more. Anthocodiae retractile into very low ver- 
rucae scarcely separable from surrounding co- 
enenchyma; aperture with eight distinct lobes. 
Verrucae on all sides of the branches, mostly 
0.75 to 1.0 mm. apart. Anthocodial armature 
of eight points of spindles in converging rows 
and collaret of short spindles transversely ar- 
ranged. Axis composed of smooth, irregularly 
branched spicules and horny substance. Color, 
in life, bright orange; in dry condition, dirty 
brown. Sclerites of deep layers of coenenchyma 
blunt spindles with prominent belts of warts; 
in superficial layers double clubs or double 
wheels with smooth, sharply constricted shaft; 
those at surface with heads unilaterally produced 
into a pair of granular lobes. 
Spicule measurements: 
Spindles: 0.1 X 0.04 mm.; 0.08 X 0.045 mm. 
Symmetrical double clubs: 0.05 X 0.034 mm.; 
0.026 X 0.02 mm. 
Asymmetrical double clubs: 0.03 X 0.03 mm.; 
0.045 X 0.035 mm. 
Eocality: Enyu Island, Bikini Atoll, on edge 
of a large coral knoll in about 45 feet of water, 
August, 1947. 
Specimen: Dry fragments, U.S.N.M. No. 
44074. 
Remarks: This specimen, of which the U. S. 
National Museum possesses only fragments, 
was about 8 feet high when complete, and so 
large that only one of the branches could be 
collected. Dr. Robert W. Hiatt, of the Univer- 
sity of Hawaii, found it while diving on a sub- 
merged reef off Enyu Island. When alive the 
colony was a bright orange color, according to 
Dr. Hiatt, but after a few hours in the air it 
assumed the brownish hue which it still re- 
tains. The greater part of the specimen is in 
the collection of the University of Hawaii. 
Stiasny first recognized that Nutting had 
erred in calling this scleraxonian a plexaurid. 
However, the calcareous deposits of the axis take 
a definite spicule form, unlike those of the 
Plexauridae. In its cortical spiculation it is 
similar to S. verriculata, although the asymme- 
trical double wheels of the surface layers are not 
identical with those figured by Aurivillius
