no. 1624. DESCRIPTIONS OF HAWAIIAN ALCYONARIA—NUTTING. 585 
Genus ECHINOMURICEA Verrill. 
Calyces short, cylindrical, conical or truncated; tentacular opercula 
horizontal; spicules long flat needles, with branched ends. 
ECHINOMURICEA BRUNNEA, new species. 
Plate XLV, fig. 1; plate XLIX, fig. 4. 
Colony incomplete, flabellate in form, attaining a height of about 
75 mm., consisting of a central stem which branches in a straggling 
manner. 
Calyces usually borne on opposite sides of stem and branches, but 
in places on all sides, low, dome-shaped, and about 2 mm. high by 24 
mm. broad at base. 
Polyps completely retractile, so that there is not even a distinct 
opening at the top of the calyx. 
Spicules small, of exceedingly varied form, many being spindle 
shaped with both ends branched and forked, some being star shaped, 
and some resembling the paxille of starfish in miniature. They 
cover the surface of calyces and cortex, looking much lke grains of 
sand under the dissecting lens. There is a circlet of pointed spicules 
around the top of the calyx at the margin of inversion, and there 
are a few large warty spindle-shaped spicules arranged en chevron on 
basal part of tentacles and longitudinally on distal part. 
Color.—A uniform sandy brown. 
Type.—Cat. No. 25325, U.S.N.M., Station 4079, between Hawau 
and Maui, 143-178 fathoms. 
- Distribution.—South coast of Molokai: Station 3838, 92-212 fath- 
oms (Cat. No. 22596, U.S.N.M.). 
Between Molokai and Maui: Station 3859, 138-140 fathoms; Sta- 
tion 3863, 154 fathoms (Cat. No. 25420, U.S.N.M.); Station 3885, 
136-148 fathoms (Cat. No. 25327, U.S.N.M.) ; Station 4100, 130-151 
fathoms (Cat. No. 25328, U.S.N.M.). 
Between Hawaii and Maui: Station 4079, 143-178 fathoms (Cat. 
No. 25325, U.S.N.M.). 
This species bears much superficial resemblance to the Gorgonida, 
but is distinctly amuriceid, and appears to belong to this genus, as 
is shown by the arrangement of spicules in the polyps. 
Genus CYCLOMURICEA, new genus. 
Colony flabellata ; calyces short, stout, columnar, their walls with 
spicules transverse te the axis of the eae and forming annular rings 
around it. Spicules warty spindles. 
Type.—Cyclomuricea flabellata,
