19, 2 Light: Notes on Philippine Alcyonaria 251 
spotted appearance. It differs from all but L. australasix in 
that the axis does not extend to the upper end of the colony, 
and from L. australasiz in that the axis is deeply grooved on two 
sides in the region of the rachis and in the ‘large size of its 
autozooids. From L. hicksoni, to which it is apparently most 
nearly related, it differs, aside from the difference in the length 
of the axis and the presence of the brown spot on the upper 
basal portion of the polyp, in the greater length of the rachis 
as compared with the stalk, in that the siphonozooids are ar- 
ranged in distinct longitudinal rows, and in that the autozooids 
are considerably smaller. 
I have named this species after Dr. Willy Kiikenthal, whose 
revision of the Pennatularia has greatly facilitated systematic 
work in that group. 
Lituaria philippinensis sp. nov. 
Type.—No. C. 2459 in the Zodlogical collection, College of 
Liberal Arts, University of the Philippines; collected from Port 
Galera Bay, Mindoro, by R. P. Cowles. 
The colony is slender and, with the exception of the lower 
portion of the stalk, rigid. The rachis is somewhat longer 
than the stalk and has a maximum diameter slightly less than 
that of the somewhat swollen lower portion of the stalk. The 
axis, which extends from the midportion of the stalk to the 
extreme tip of the rachis, is four-sided, slender, recurved at its 
lower end, and grooved on two sides throughout its whole length. 
It tapers from the middle of the rachis to the very slender 
lower tip, and less so toward the upper end, which is bluntly 
pointed. The grooves-do not join over the upper end. 
The polyps are scattered jor in indistinct transverse rows or 
whorls, being from 2 to 3 millimeters apart in the long axis of 
the colony, and from 1 to 2 millimeters apart in the transverse 
axis. They are completely retractile within upwardly directed, 
flaplike, basal portions, which have a triangular, spiculated re- 
gion on their outer ‘surfaces. The polyps have transparent 
white walls with black or brown tentacles, or white tentacles 
and a brown stomodeum. The siphonozooids are numerous 
and distinct, irregularly arranged, each with a small nonre- 
tractile basal portion similar to that of the autozooids. 
The spicules are unbranched or bluntly branched, sculptured 
capstans averaging 0.13 millimeter in length and 0.025 in 
central diameter.
