filaments; no other species listed in Table 48 has more than
eight.
Andrews (1891:285) stated that this species is "not uncommon
on sponges, etc., in 2 to 3 fathoms in sheltered sounds. The
young were also found cast up on the Fort beach, after storms,
upon seaweeds."

COMMENTS ON MATERIAL EXAMINED.—The type is not
available. The following represents a summary of information
in the original description.
DESCRIPTION.—Type a posteriorly regenerating specimen;
length 21.5 mm; width 5 mm with parapodia; regenerating
portion 1.5 mm long. Number of segments 37 in region
preceding regenerate.
Prostomium very short, with clavate antennae; A-III to
setiger 1, with 4 large, slightly barrel-shaped articulations.
Jaws not examined.
Branchiae present, pectinate. Branchiae from setiger 5,
present on last segment in non-regenerating part of body.
Maximum number of filaments 5-6.
Ventral cirri apparently inflated in most of branchial region.
Notopodial cirri clavate, without articulations.
Pectinate setae illustrated with both marginal teeth longer
than other teeth, narrow, tapering with -10 teeth. Shafts of
compound falcigers tapering. Appendages short, with large
heads, bidentate. Proximal teeth larger than distal teeth. Guards
symmetrically rounded; mucros absent. Pseudocompound
falcigers and compound spinigers absent. Aciculae and
subacicular hooks black. Subacicular hooks bidentate. Hooks
first present from setiger 35. Proximal teeth larger than distal
teeth, directed laterally. Hooks with distinct subterminal
inflated region.
UNKNOWN MORPHOLOGICAL FEATURES.—Many features
from all parts of the body.
EXPECTED STATES OF SELECTED UNKNOWN FEATURES.—
None.
CHARACTERS USED IN PREPARATION OF KEY NOT
SCORED.—Inappropriate Characters: 60. Unknown Characters:
1, 2, 4-19, 23-29, 32-34, 36-40, 42-56, 58, 59, 65,
67,74-76,81,82.
ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—
None.
REMARKS.—This species belongs to group B, but cannot
safely be assigned to a subgroup, because the branchial
distribution in intact animals remains unknown; for that reason
it has been listed both in Tables 24 and 27 as well as in Table
31. It is too poorly known to be safely identified from the
original description. The species was reported from southern
Japan.
