no. 1624. DESCRIPTIONS OF HAWAIIAN ALCYONARIA—NUTTING. 581 
Polyps irregularly but sparsely scattered over main stem and larger 
branches, more approximate on distal parts, where they often be- 
come quite regularly alternate; those on the same side being about 
8mm. apart. They project at a right angle from the branches and 
are 2 to 3 mm. high to the end of the operculum, varying from a 
rough cylinder to the frustrum of a cone in shape; average diameter 
below collar about 2 mm. 
Spicules warty spindles, large and stout, often forked or branched, 
arranged in circles at bases of the calyces, and vertically placed in 
the calycular walls without forming eight longitudinal coste that 
are as distinctly marked as in other species of this genus. At the 
margin a few not very prominent points arise. The collar is quite 
well marked, and is composed of rather slender spindles with in- 
conspicuous verruce or none. The opercular spicules are slender, 
curved, warty spindles, covering the dorsal side of the tentacles in 
longitudinal bundles of four to eight. Spicules of the coenenchyma 
rough, coarse spindles arranged longitudinally, in a general way, 
but often more or less irregular in disposition. 
Color of main stem and branches dark golden brown. ‘The rest 
of the colony is grayish brown. 
Type.—Cat. No. 25358, U.S.N.M., Albatross station 4186, off 
Kauai, 508-682 fathoms. 
Genus ANTHOMURICEA Wright and Studer. 
Calyces cylindrical, projecting perpendicular to the axis. Spindle- 
shaped spicules arranged en chevron both on body walls and on 
proximal parts of tentacles. 
ANTHOMURICEA TENUISPINA, new species. 
Plate XLIV, fig. 2; plate XLVIII, fig. 5. 
Colony flabellate in form, attaining a height of about 375 mm., 
growing from a basal disk-shaped concave flap of leathery con- 
sistency. Stem 7 mm. thick, almost straight proximately and sinu- 
ous distally, giving off large and small branches on opposite sides; 
branches subdividing several times, sometimes giving off regularly 
opposite twigs, and at others showing no regularity whatever. 
Polyps scattered sparsely on the main stem and branches, more 
crowded distally. On the branchlets they are arranged in irregular 
whorls of three or four, and are only about 2 or 3 mm. apart. The 
twigs end in a broad lobular expansion on which is placed a group 
of three to five polyps. |
