NOTES ON PHILIPPINE ALCYONARIA 
PART VI: NEW PHILIPPINE PENNATULARIA (SEA PENS) OF THE 
GENUS LITUARIA 
By S. F. Light 
Professor of Zoology, College of Liberal Arts, University of the 
Philippines 
The Philippine Pennatularia have been little studied, only- 
eleven species being known from the Islands, all from the collec- 
tions of Semper 1 and the Challenger. 2 
The present report deals with the specimens belonging to the 
genus Lituaria in the collection of the department of zoology, 
College of Liberal Arts, University of the Philippines, which 
represent four species, all new to science. 
The only other representative of the suborder Sessiliflorse in 
the collection is the Policella manillensis of Kolliker, 1 here re- 
ported for the first time since Kolliker. 
In this report I have adopted the systematic arrangement of 
the group suggested by Kiikenthal in his revision, 3 and have fol- 
lowed him closely in the diagnosis of the genus Lituaria and the 
key to the species of the genus. 
Suborder SESSILIFLORvE 
Polyps arising singly and directly from the rachis. 
Section Pennatulina radiata 
Polyps arising on all sides of the rachis. 
Family VERETILLIDiE 
Polyps without a distinct calyx. 
Genus LITUARIA Valenciennes MS., 1850 
Colony club-shaped. Autozooids widely separated, scattered 
or in longitudinal rows. Siphonozooids very numerous, filling all 
the spaces between the autozooids. Axis of varying length and
