crosses and other aberrant forms (Fig. 6 b). 
The thick walls of the body tubes contain 
coarsely warted, blunt rods 0.15-0.2 mm. in 
length (Fig. 6 c). The lower part of the coe- 
lenteric cavity beginning about 5 mm. from 
• the mouth is filled in, except for eight longi- 
tudinal canals, with spiculiferous mesogloeal 
intrusion tissue, to form a stem perforated by 
eight stem canals. It is from this "stem” 
region that subordinate zooids arise, all of 
which show similar tissue in their coelenteric 
cavities as soon as they exceed 7 or 8 mm. in 
length. The intrusion spicules are branched 
sclerites about 0.27-0.3 mm. long (Fig. 6 d), 
of the same type found in other species of 
the genus. The stolons contain slimmer, 
warted rods, crosses, and branched forms 
smaller than those in the intrusion tissue 
(Fig. 6 e). 
In alcohol the colonies are pale brown or 
whitish. 
TYPE: U.S.N.M. No. 22574. Oahu Island: 
Diamond Head Light bearing N.7°E., 12.5 
miles distant, in 311-337 fathoms, fine gray 
sand and mud, bottom temperature 43.7°F.; 
May 5, 1902 ("Albatross” station 3910). 
RECORDS: South of Oahu Island: 21°08' 
N., 157°43'W., in 351 fathoms, fine white 
sand, bottom temperature unknown; De- 
cember 6, 1891 ("Albatross” station 3475). 
Oahu Island: Diamond Head Light bearing 
N.23°10'E., 16.4 miles distant, in 289-292 
fathoms, gray sand, mud, bottom tempera- 
ture unknown; May 6, 1902 ("Albatross” 
station 3914). 
REMARKS: This species may be recognized 
by its very slender body tubes, less than 1 mm. 
in diameter, and its small, oval spicules. 
Nutting’s paratype consisted of specimens so 
different that I am here describing them as a 
distinct subspecies. 
Telestula spiculicola rohusta n. subsp. 
Figs. 7 c-e, 8 
Clavularia spiculicola (part) Nutting, 1908, 
U. S. Natl. Mus., Proc. 34: 553, pi. 41, 
fig. 1. 
Specimens (including some paratypes of 
spiculicola) from four stations are distinctly 
more robust than the type of Clavularia 
spiculicola. The diameter of the body tubes is 
regularly from 1 to 1.25 mm., even in young 
primary zooids (Fig. 7 c-e). The spiculation 
in general is very similar, but the major 
sclerites of the body tubes are distinctly 
larger (0.35 mm.) and frequently pointed 
(Fig. 8 c), and those of the neck zone (Fig. 
8 h) are larger and of different form. As in T. 
spiculicola s.s., the tentacles are densely spicu- 
late: short rodlets transversely encircle the 
rachis of the tentacles, chiefly in two dorsal 
(aboral) and two adoral tracts, and extend in 
small groups into the pinnules. The inner and 
outer stolon spicules are like those of the in- 
trusion tissue and body tubes, respectively, 
but there are, in addition, more crosses, 
branched plates, and irregular forms. 
type: U.S.N.M. No. 43097. Between Maui 
and Molokai Islands: Mokuhooniki Islet 
bearing S.80°30'W., 7.8 miles distant, in 
277-284 fathoms, globigerina ooze, bottom 
temperature 45.2°F.; April 16, 1902 ("Alba- 
tross” station 3883). 
REMARKS: The figure given by Nutting on 
plate 41 represents this subspecies, but it is 
impossible to be absolutely certain from 
which specimen the illustrated spicules were 
taken. The spicules are so vaguely depicted 
as to render the figure worthless. 
The subspecies rohusta can be separated 
from Telestula spiculicola s.s. by the stouter 
body tubes frequently measuring 1.25 mm. 
in diameter and 100 mm. in length, and by 
the larger, usually pointed spicules of the 
body walls. The differences in the neck zone 
sclerites can best be seen by comparing the 
figures of those of the subspecies and of the 
typical form.
