A Review of the Genus Eunice - Smithsonian Institution Libraries

86 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
Type yellow with white punctations, with 96 setigers.
Antennae with up to 12 long articulations in A-III. A-I to
posterior peristomial ring; A-II to setiger 3; A-III to setiger 5.
Branchiae from setiger 3 through setiger 27; all pectinate
with up to 9 filaments.
Notopodial cirri about as long as branchiae, vaguely
articulated.
Aciculae yellow.
The branchial distribution combined with the information
about the antennae and the color of the aciculae indicate that
this species might be a member of C-l, but the information is
clearly insufficient to identify the species and it is here
considered indeterminable.

MATERIAL EXAMINED.—Part of holotype, ZMB F 1993b
(marked Eunice magnified, see comment below), Samoa, 3
parapodia.
COMMENTS ON MATERIAL EXAMINED.—G. Hartwich (in
litt.) informed me that parapodial preparations of E. bipapillata
and E. magnifica originally were stored together in the same
vial; at one time they were split apart into two vials. The three
parapodia referred to above agree with E. bipapillata and
cannot agree with E. magnifica due to differences in the
distribution of branchiae and the different maximal numbers of
branchial filaments reported by Grube for the two species.
Therefore, it is assumed that the labels for the two vials were
confused. The description given below is a summary of
observations on the parapodial preparations and the original
description.
DESCRIPTION.—Type copper-colored with white band across
setiger 4.
Ceratostyles articulated.
Branchiae (Figure 23d,h,i) present, pectinate, distinctly
shorter than notopodial cirri, not reduced in mid-body region.
Branchiae from setiger 4 to end of body. Branchiae present to
near posterior end, present on more than 65% of total number
of setigers. Up to 4 filaments from setiger 8 through setiger 18;
paired filaments in setiger 77. Branchial stems short, tapering.
Filaments digiuform.
Anterior acicular lobes (Figure 23d,e) asymmetrically
truncate, with aciculae emerging above midline, becoming
slightly triangular in posterior setigers (Figure 23i). All
pre- and postsetal lobes low folds. Ventral cirri distinctly
inflated basally in setigers 15 and 18; inflated base lost by
setiger 77; narrow tip digitiform in all setigers. Ventral cirrus in
setiger 77 digitiform. All notopodial cirri similar in size and
shape; bases slightly inflated, tapering to blunt, digiuform tips,
without articulations.
Limbate setae longer than other setae, slender, narrowly
limbate, marginally serrated. Shafts of pectinate setae (Figure
23b,h) cylindrical, slender; blades slightly flared, flat. One
marginal tooth longer than other teeth; up to 15 teeth. Shafts of
compound falcigers (Figure 23a,c) tapering, marginally
smooth; distal beak indistinct. Appendages short, relatively
thickset with large heads, bidentate. Proximal teeth triangular,
directed laterally or slightly distally, with distinct distal
upturned tip; distal teeth longer than proximal teeth, tapering or
blunt, directed obliquely distally. Guards asymmetrically
bluntly pointed, without mucros. Pseudocompound falcigers
and compound spinigcrs absent. Aciculae paired, black,
tapering, straight, blunt-tipped; cross-section round. Subacicular
hooks (Figure 230 black, bidentate. Hooks absent in
parapodia 15 and 17, present in parapodium 77. Proximal tooth
thicker than distal tooth, but no longer, curved, directed
laterally. Distal tooth nearly erect, tapering. Guard short,
truncate.
UKNOWN MORPHOLOGICAL FEATURES.—All features associated
with prostomium and pcrisiomium; jaw structure;
distribution of branchiae and subacicular hooks.
EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA-
TURES.—Antennae not reaching beyond pcristomium; with
cylindrical articulations or without articulations; digitiform.
Mx III short; located in front of left Mx IV, forming part of a
distal arc. Branchiae continued to far posterior setigers.
CHARACTERS USED IN PREPARATION OF KEY NOT
SCORED.—Inappropriate Characters: 56, 58, 59. Unknown
Characters: 1-20, 22-29, 33, 34, 36-40, 51, 52, 74, 78,
80-82.
ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—20,3;
22,2; 23,4; 33,2; 37,1; 38,1.
REMARKS.—Eunice bipapillata is listed with similar species
in Tables 27, 30, and 31; it resembles in certain respects E.
aphroditois, but cannot be completely identified without access
to more material.
Eunice bitorquata Grube, 1870
Eunice bitorquata Grube, 1870b:56.
Eunice siciliensis.—Grube, 1878a: 101.
REMARKS.—The original description contains the following
statements (K. Fauchald translation):
The species is brown with golden to brown cross bars on the peristomium.
Branchiae are present from setiger 104 and are present only as single filaments,
far outreaching the notopodial cirri. Segments are remarkably short and the
median antenna is as long as four segments. The maxillae have coarse teeth; Mx
II has 4 teeth.
Grube (1878a: 101) referred this species questionably to his
own Eunice siciliensis, but gave no comment or any supportive
statements.
The original description is wholly inadequate to characterize
the species; the information given is consistent with the
synonymy suggested by Grube (1878a), but is not sufficient to
be conclusive. Eunice bitorquata is here considered indeterminable.
