Zootds.—Much less numerous than is usual in this genus. There is 
a row of eight to twelve on ventral side at junction of each leaf with 
the rachis, each zooid being surrounded by a circlet of spicules con- 
verging at their distal ends. 
Color.—Bright yellow throughout. 
Type.—Cat. No. 22579, U.S.N.M., Albatross station 4101, between 
Molokai and Maui, 122-1438 fathoms. 
Distribution Between Molokai and Maui: Station 3859, 1388-140 
fathoms (Cat. No. 22576, U.S.N.M.). 
Between Maui and Molokai: Station 3864, 163-198 fathoms; Sta- 
tion 4102, 122-132 fathoms (Cat. No. 22578, U.S.N.M.). 
Off Tbeseem Island: Station 3957, 173-220 fathoms (Cat. No. 22581, 
WESANE ME): 
Northwest coast of the Island of Hawaii: Station 4079, 143-178 
fathoms (Cat. No. 22577, U.S.N.M.). 
The specimen from Station 3864 was 104 inches long. 
PENNATULA PALLIDA, new species. 
Plate XLI, figs. 9 and 10. 
Largest specimen 175 mm. long; stem to first rudimentary leaf 28 
mm.; rachis, including portion bearing the rudimentary leaves, 112 
mm. long. The stem is swollen at the base, with another bulging por- 
tion about 25 mm. above the end bulb. 
Functional leaves nineteen on each side, long, much narrower pro- 
portionally than in other species, 11 mm. long, 4 mm. broad at base, 
recurved. 
Polyps usually four to each leaf, short, the calyces inclined toward 
the distal ends of the leaves so much that the outer side of one is 
adnate to the inner side of the next one nearly to the margin of the 
former ; margin flaring, with about eight acute spines. Calyces 2 mm. 
long on inner side, and 2 mm. broad. : 
Spicules.—The spicules of this species are large and conspicuous, 
of the usual needle-shaped type, crowded over the entire surface of 
rachis, stem, leaves, and calyces, their points often projecting, giving 
a harsh, hirsute appearance under a low magnification, except on the 
lower part of stem, which is comparatively smooth. The spicules are 
crisscrossed in every direction on leaves and lower part of calyces, 
but on the upper parts of the calyx walls they are vertical, and 
arranged in eight rib-like bands which project upward into the eight 
marginal teeth. The tentacles are without spicules. 
Zooids.—A row of about a dozen zooids joins the adjacent leaf 
bases on the ventral side of the rachis. There are other but shorter 
_ rows on the latero-dorsal ridge, which is plainly marked in this 
species. The hirsute appearance of the rachis, already referred to, 
makes it difficult to count the zooids with certainty.
