shape. Colony obviously dead when collected, the coenosteum
well worn and discolored to a light brown. Branches robust,
basal branches about 31 mm in diameter, distal blunt tipped
branches about 13 mm in diameter, branch anastomosis
common. Corallites 5-6 mm in diameter and flush with
coenosteum, perhaps due to wear of corallum. Theca vermiculatc
as well as obscurely costate, the coenosteum penetrated by
numerous small (0.32 mm in diameter) circular pores (?borings).
Septa hexamerally arranged in 4 cycles in a Pourtales
Plan, some of the larger corallites having several pairs of S5. S,
slightly wider than S2, both cycles of septa attaining the
columella. S3 narrowest of septa, each S3 flanked by a pair of
S4 which fuse before the S3 and extend to the columella. Fossa
shallow, containing a large, spongy columella.
DISCUSSION.—Dendrophyllia cribrosa is treated as a member
of the first group of species as defined in the generic
discussion because it has an arborescent corallum and
nonsympodially budded corallites. It is relatively easily
distinguished from other North Pacific species by having thick,
anastomotic branches; very short (flush) corallites oriented
perpendicular to parent branches; circular corallites 4.5-8.0
mm in diameter, and a robust columella. The proper authorship
of the species is Milne Edwards and Haime (1851), not Milne
Edwards and Haime (1860), as suggested by some authors.
Blainville's earlier names published in lists must be considered
as nomina nuda and de Haan's Oculina anastomozans was
apparently only another unpublished manuscript name cited by
Blainvilic (1830).
MATERIAL EXAMINED.—New Records: None. Previous
Records: Larger syntype of D. cribrosa. RMNH.
TYPES.—Two syntypes (Plate 38tf./i) of D. cribrosa are
deposited at the RMNH: the larger specimen described above
(RMNH 9212. manuscript type of Dentipora anastomozans)
and a much smaller fragment 8.2 cm long (RMNH 9209,
manuscript type of Dentipora cribrosa). Type Locality:
Unknown.
DISTRIBUTION.—Japanese region: Sagami Bay. Honshu;
?Sea of Japan off eastern and southern South Korea (Song,
1982); Pleistocene of Kanagawa-ken; 7-40 m. Elsewhere:
Off Banka. southeastern Sumatra; ?off Angola (Cabinda)
and the Congo; 20-30 m.

DIAGNOSIS.—Colonies consist of a primary axial corallite up
to 9 cm in height and up to 27 mm in GCD from which several
slightly smaller, but still quite robust, corallites bud at irregular
intervals. All colonies examined as well as those reported in the
literature arc broken basally. but it would appear from the larger
diameter of the basal fractures that the normal condition of the
SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
species is attached, not free as in Eguchipsammia. Costae are
flat and porous; epitheca absent. Septa hexamerally arranged in
a Pourtales Plan, larger corallites having a full fifth cycle of
septa (96), smaller corallites usually having numerous pairs of
S5. Su2 equal in size, slightly exsert, and quite wide, their
smooth inner edges bordering the columella. S3 and S4
progressively smaller. Pairs of S5 fuse before their adjacent S4
and again before the S3 in their half-system before reaching the
columella. Fossa deep, containing an elongate narrow columella.
DISCUSSION.—Dendrophyllia japonica belongs to the "second
group" of Dendrophyllia species, those characterized as
bushy, having small colonies with sparsely budded large
corallites. It is compared to D. arbuscula in the account of that
species.
MATERIAL EXAMINED.—New Records: None. Previous
Records: Specimens reported by Squires and Keyes (1967)
from off New Zealand, NZOI.
TYPES.—Two syntypes of Rehberg's D. japonica were
present at the ZMB in the 1920's (Van der Horst, 1926), but it
is likely that they were subsequently lost or destroyed. Type
Locality: "Japan," depth unknown.
DISTRIBUTION.—Japan: Sea of Japan off northwestern
Honshu from Tsugaru Strait to Wakasa Bay; Sagami Bay;
115-250 m. Elsewhere: Banda Sea; North Island, New
Zealand; 114-549 m.
