Hawaiian Octocorals — Bayer 
contain long, somewhat bent, tuberculate 
spindles reaching 1.5 mm. in length; those of 
the inner canal walls are smaller and more 
slender. Color (in alcohol) white; usually all 
spicules white, sometimes those of the crown 
and points pink. 
TYPE: U.S.N.M. No. 25361. Between Maui 
and Molokai Islands: Mokuhooniki Islet 
bearing N.8°30'E., 4.8 miles distant, in 143- 
122 fathoms, coral sand, shell, and foramini- 
fera; bottom temperature 59.7°F.; July 23, 
1902 ("Albatross” station 4101). 
REMARKS: Siphonogorgia alexanderi seems to 
approach S. variabilis Hickson, originally de- 
scribed from the Maidive Islands, and may 
eventually prove to be the same. The differ- 
ences between many of the published species 
of Siphonogorgia are so vague that only by a 
complete revision can their status be decided.

Monog. 13d: 154. 
DIAGNOSIS: Branches thick; calyces tubu- 
lar, about 3 mm. tall, into which the antho- 
codiae are fully retractile. Entire surface of 
branches and calyces covered with large, ill- 
fitting, thick plates which become more 
spindle-like near the verrucal margins. An- 
thocodiae with a wide collaret of about 10 
transverse rows of curved spindles, and eight 
points each consisting of a pair of large 
spindles and one or two pairs of smaller 
accessory spindles. In the walls of the stem 
canals there are smaller, warty spindles. 
type: U.S.N.M. No. 25318. Laysan Island 
Light bearing S.79°30'E., 7.3 miles distant, in 
57-79 fathoms, white sand, broken shell, and 
corallines; bottom temperature 71.1°F.; May 
16, 1902 ("Albatross” station 3935). 
REMARKS: The single fragment obtained 
indicates a colony with thick branches, but 
it may just as well have been an unbranched

type fragment. 
Nidalia-like colony only the top of which was 
sheared off by the dredge. The tall, tubular 
calyces with their anthocodiae usually more 
or less exsert, the surface pavement of large 
plates, and the thick, digitate branches 
should render the species recognizable when 
found again. 
Color "coral red” (in life?); in alcohol, 
ivory white, the soft tissue dull brownish.

DIAGNOSIS: Stolon membranous, filled with 
bent spindles. Calyces truncate conic, their 
spicules in the form of spindles arranged ob- 
scurely en chevron in eight interseptal tracts. 
Anthocodial neck zone long, with trans- 
versely disposed, scattered, small spindles 
which grade into the strong collaret. Tentacle 
bases with several pairs of spindles en chevron
