BARBADOS-ANTIGUA EXPEDITION 111 
Barbados and may be the one just mentioned. Other species 
occur in the Kast Indies, while two are reported from Patagonia. 
An interesting find is a species of Versluysia, a genus. insti- 
tuted by the writer to accommodate certain forms collected in 
the Dutch East Indies by the famous ‘‘Siboga’’ expedition, 
which secured a magnificent series of gorgonians upon which it 
was the privilege of the writer to report. The genus is charac- 
terized by having a superficial layer of enormous spindle-shaped 
spicules placed lengthwise on the stem and branches, where 
they are not always in contact, revealing another layer of 
smaller and more slender spicules beneath. The spicules of the 
ealyces are not arranged en chevron. A specimen secured by us 
measures nine centimeters in height and represents but a por- 
tion of the colony. It is sparingly branched, dark brown in 
color but rendered silvery by the frosting of the very large 
spicules by which it is covered. The outer layer is composed 
of comparatively enormous spicules, some as much as five 
millimeters in length. They are laid lengthwise on the stem 
and branches and curved to fit the surface and accommodate 
themselves to the contour of the calyx bases around which 
they bend. They look as though they were simply stuck on the 
branches, which they do not cover, leaving spaces through 
which the underlying spicules can be seen. The ecalyces are 
low, conical, or dome-shaped. 
This is, I believe, the first record of the occurrence of Ver- 
sluysia in the Atlantic, the other members of the genus being 
reported from Ceylon or the East Indies. The genus is named 
in honor of my friend, the distinguished Dutch naturalist, 
Dr. Versluys, a member of the Siboga expedition, which se- 
cured the largest number of Muriceide (96 species) that has 
ever resulted from a single expedition, more than three times 
as many as were taken by the justly famous Challenger expe- 
dition. 
A representative of the beautiful genus Chrysogorgia was 
taken at Station 8, depth 80 fathoms. The calyces are all on 
the upper sides of the branches, the latter being geniculate and 
covered by a very thin cenenchyma. The axis cylinder of this 
genus is noted for its brilliant metallic iridescence. 
A specimen secured at Station 51, depth about 33 fathoms, is
