PACIFIC SCIENCE, Vol. Ill, July, 1949 
Locality: Station 30. 
Specimens: The holotype, U.S.N.M. No. 
44084, and 11 paratypes, U.S.N.M. No. 44085, 
preserved in alcohol. 
Remarks: The specimens represented in the 
Resurvey Collection measure as follows: 
Holotype: 145 X 120 mm. 
Paratypes: 150 X 120 mm. 
125 X 90 mm. 
75 X 115 mm. 
45 X 22 mm. 
12 X 18 mm. 
2 1 X 8 mm. 
80 X 57 mm. 
47 X 45 mm. 
70 X 45 mm. 
50 X 42 mm. 
40 X 25 mm. 
In the measurements given above, the height is 
listed first. The third, fourth, fifth, and sixth 
paratypes are all attached to the same fragment 
of coral, and show the • variation in shape of 
colonies at different ages. In a fully adult colony, 
the stem measurements are as follows: Stem, 
diameter 3.0 mm.; branch, 1.5 mm.; twig, 1.0 
mm. In small specimens, all the branches are 
about 1.0 mm. in diameter. 
The sclerites of this species, when carefully 
cleaned and examined under a dissecting micro- 
scope, are among the most beautiful of all 
alcyonarian spicules. The accompanying illus- 
trations leave much to be desired in conveying 
their crystalline appearance. 
It is with pleasure that I name this new 
species for Fred Zimmerman, whose sincere 
enthusiasm and faithful assistance were great 
assets on many collecting trips. 
Villogorgia zimmermani form pallida new 
Figs, lb, 3a-d; PI. 3, fig. 2 
Diagnosis: Similar to V. zimmermani s.s., ex- 
cept: color, pale yellowish-brown, with colorless 
spicules; colony less robust, stems measuring 2.5 
mm. in diameter, branches 1.25, and twigs 0.75; 
verrucae also somewhat smaller. Spicules same 
size as in typical form, but completely without 
rose-purple color. Operculum identical to that 
of typical form. 
Locality: Station 30. 
Specimen: The holotype, U.S.N.M. No. 
44086. 
Remarks: Although this specimen is not 
specifically distinct, it differs so markedly in 
color, and in its general slenderness, that it 
seems advisable to separate it from V. zimmer- 
mani as a form. 
Villogorgia compressa Hiles 
Figs. 1 c, Aa-b\ PL 2, fig. 2 
Villogorgia compressa Hiles 1899: 200, pi. 22, 
fig. 7. 
Villogorgia compressa Nutting 1910^: 71. 
Brandella compressa Kiikenthal 1924: 218. 
Villogorgia compressa Aurivillius 1931: 225. 
Diagnosis: Colony erect, flabellate, branched 
in one plane, with frequent anastomosis of both 
large and small branches. Branching irregular. 
Main stem oval in cross section, 1.0 by 2.0 mm. 
in diameter, flattened at right angles to plane of 
branching. After first major division of trunk, 
stems strongly compressed, 0.75 by 1.75 mm. in 
diameter; end twigs round, 0.5 mm. in diameter. 
Anthocodiae retract into prominent tubular ver- 
rucae set at right angles to stems. Verrucae 
from 0.75 to 1.0 mm. in height, slightly less in 
width, irregularly scattered over colony, less 
abundant on "rear face.” End twigs usually with 
opposed pair of zooids. Axis horny, light brown, 
becoming paler distally. Color of dry colony 
dirty brown. Sclerites of verrucae horizontally 
arranged, with a short projecting portion of one 
or two short, finger-like processes, and with two 
flattened, branched roots. Sclerites of coenen- 
chyma quadriradiate forms of smaller size. An- 
thocodial armature eight pairs of flattened spic- 
ules arranged longitudinally and forming eight 
points; transverse rows beneath these merge 
with transverse verrucal spicules, hence collaret 
without well-defined proximal boundary. 
Spicule measurements : 
Spicules of verrucae: 0.25 X 0.01 mm.; 0.24 X 
0.01 mm.; 0.26 X 0.125 mm.
