crigins two-fifths, right-handed.« The distance between branch 
origins is about 3 mm., and the shghtly ascending branches subdivide 
about four times. Normal polyps ordinarily one to each node, but 
two to a node on distal parts; small, rather slender, 14 to 2 mm. high. 
Besides these there are a number of large abnormal polyps infested 
with parasitic crustacea. These polyps are in some cases as much as 
12 mm. high by 2 mm. in diameter. 
Spicules, usually bar-like, arranged longitudinally on body walls 
and in tentacles. Not seldom irregular, branched forms are seen. The 
spicules in the modified polyps are larger than elsewhere, and tend to 
be more irregular. Here also they are arranged longitudinally in the 
body walls. 
Color of main stem ght drab, main branches hght yellow, polyps 
almost white. It is probable that the branches and polyps are bright 
yellow in life. 
The stem has a dull greenish iridescence, where denuded, and this 
becomes lighter green where the axis of the branches js seen.

French Frigate Shoal, 895-397 fathoms.

CHRYSOGORGIA DELICATA, new species. 
Plate XLV, fig. 7. 
Colony, incomplete, about 50 mm. in height, with exceedingly deli- 
cate stem and branches, the latter with but one or two bifurcations. 
Spiral left-handed, one-third to a whorl; distance between branch 
origins 4 mm. 
Polyps about 24 mm. high, quite distant from each other, a single 
one to a node, except where there are two on a distal node, much de- 
composed and hard to study in the specimens secured. 
Spicules squamiform, but so varied in form and size as to be almost 
beyond description. They are rather large, with many lobular proc- 
esses from their edges, and are imbricating and interlocked in an 
exceedingly complex manner. They often have forked, lobular ends, 
resembling those of C. axillaris. Their general trend seems to be 
longitudinal in polyp walls, although there is a tendency to become 
transverse on the polyp bases. Tentacular spicules curved, placed 
transversely. 
4 These terms are used by Versluys. ‘‘ Branch origins two-fifths’ means that 
starting with a given branch origin, and following the origins of successive 
branches upward, the sixth branch origin will be directly above the first, and 
that the spiral traced through the branch origins will have passed meanwhile 
twice around the stem. ‘“ Right-handed” means that the spiral passes upward 
in an opposite direction to that taken by the hands of a watch,
