somewhat upwardly directed, heavily spiculated, verruca-like 
basal regions about 2 millimeters in diameter, whose large size 
in proportion to the diameter of the rachis gives the colony a 
characteristic, irregular appearance. 
The siphonozooids are numerous and irregularly arranged 
and have spiculated nonretractile basal regions, similar to those 
of the autozooids, and are about 0.8 millimeter in diameter. In 
the lower one-third of the rachis the zooids are nonspiculated and 
8-rayed, brown on the outer surface. 
The axis is cylindrical in the stalk region ending in a 
slender recurved tip. It is four-sided in the rachis region, 
shows two shallow longitudinal furrows, and tapers toward 
the tip where, for a distance of about 10 millimeters, it is 
slightly roughened. 
There are no spicules in the retractile portions of the 
‘polyps, in the stalk rind or in the rind of the lower part of 
the rachis. Those in the upper portion of the rachis are present 
only in the verruca-like basal portions of the autozooids and 
siphonozooids. They are small, averaging about 0.085 milli- 
meter in length, sculptured, but little-branched, consisting mainly 
of plates constricted in the middle, crosses, and capstans. 
The two colonies differ decidedly in detail due to the fact that 
one is immature and the larger colony has evidently been 
broken at some time and regenerated. The above description is — 
an attempt to give a specific diagnosis. A study of new 
specimens will probably lead to some changes, but the species 
is so clearly distinct that it seemed justifiable to establish 
it here. Below are separate descriptions of the two speci- 
mens, in so far as they differ. 
Specimen A.—Apparently a mature specimen. Length of 
colony, 69 millimeters; of rachis 49; of stalk 20. Maximum 
diameter of rachis 6 millimeters, stalk 4. Stalk constricted at 
point of union with the rachis. Rachis tapering to a point. 
The axis, which extends from near the base of the stalk to 
the tip of the rachis, consists of two parts; the upper part, 
25 millimeters long, has become attached throughout most of 
its length to the flat ungrooved side of the lower portion. 
Specimen B; immature—A very slender colony 40 milli- 
meters in length. Rachis and stalk of about the same length, 
due apparently to the fact that the 8-rayed zooids found in 
the lower portion of the rachis of the mature colony have not
