xo, 1624, DESCRIPTIONS OF HAWAIIAN ALCYONARIA—NUTTING. 557 
at the base of each tentacle there are a few spicules arranged en chev- 
ron, and then a few longer and more slender spicules which are outside 
of the latter, and curved to meet each other so that their distal ends 
are parallel to the axis of the tentacle; the whole forming a rather 
high conical operculum. All of the spicules are covered densely with 
minute verruce so small as to appear as mere granules. 
Color.—Coral red. 
Type.—Cat. No. 25318, U.S.N.M., Albatross Station 3935, off Lay- 
san Island, 59-79 fathoms. 
This species differs from S. hollikert in having much more ex- 
serted and more crowded calyces. 
Order TNA LAG A: 
Colonial forms not permanently attached to the bottom or to other 
objects. Stem with an axial cavity which is often longitudinally sub- 
divided by thin partitions and contains an axis cylinder. Spicules 
needle-like or bar-like, never warty. Both polyps and siphonozoids 
are generally present. 
Family PENNATULIDAE Kolliker. 
Axis and pinne present, the latter large, and without calcareous 
ray-like bodies. Colony feather-shaped. x 
Genus PENNATULA Linneeus (part). 
The leaves or pinne have spicules scattered over their entire sur- 
face. 
PENNATULA SANGUINEA, new species. 
Plate XLI, figs. 7 and 8. 
Colony about 100 mm. long. Stem slightly expanded or swollen at 
base, 28 mm. long. Rachis 63 mm. long. Leaves about eighteen on 
each side, increasing in length from below upward to near the distal 
end, and then diminishing rapidly. Longest leaf about 32 mm. in 
length, with six polyps; an elongated triangle in shape with a maxi- 
mum breadth of 3$ mm. Calyces rather prominent, cylindrical, ob- 
hiquely placed so as to point toward distal end of leaf; height, on the 
longest side, 24 mm.; diameter, 14 mm.; margin with eight prominent, 
acute teeth composed of numerous spicules. 
Spicules.—Needle-shaped, crowding the entire surface of leaves 
and caleyees, crisscrossed in every direction. Those in caleyces longi- 
tudinally arranged in distal part and crisscrossed in proximal portion. 
Polyps without tentacular spicules.
