A Review of the Genus Eunice - Smithsonian Institution Libraries

106 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
smaller syntype is unclear; it matches the other specimen
closely and is here considered a second syntype.
Eunice cirrobranchiata is listed with similar species in
Tables 33 and 36. Eunice cirrobranchiata and E. conglomerans
have modified acicular tips; however, E. cirrobranchiata is the
only species listed in Table 36 to have subacicular hooks with
the teeth in tandem.
Eunice rosaurae also has the teeth in tandem in the
subacicular hooks. The species with this characteristic (compared
in Tables 52 and 53) can be separated as suggested in the
discussion of E. rosaurae.

REMARKS.—Quatrefages based his species on specimens
from Port-Vendres, Mediterranean Sea, identified by Claparede
as E. harassii. As far as I can see, Quatrefages based his
description solely on Claparede's written report and never saw
any specimens. Quatrefages differential diagnosis emphasized
that the antennae in Claparede's form were placed in a
semicircle and were short and had relatively few articulations.
The notopodial cirri should be articulated.
Claparede's description and illustration indicates that his
specimens belong to group B-2. The prostomial antennae are
short and are divided into seven articulations, reaching the
posterior end of the peristomium. The peristomial cirri do not
outreach the peristomium and are divided into five articulations.
The notopodial cirri are also articulated with about five
articulations. Branchiae are present from setiger 3 according to
the illustration (Claparede, 1864, pi. 2: fig. 5) and may have
seven filaments where best developed. Aciculae and subacicular
hooks have black cores and clear sheaths; the subacicular
hooks are illustrated as being very strongly curved, with a large,
laterally directed proximal tooth and a small, erect distal tooth.
The aciculae are tapering and apparently gently curved. Details
of the other setae cannot be determined, nor can the distribution
of the subacicular hook be determined.
Claparede left no material identified by him, so the validity
of this species depends solely on the description furnished.
Grube (1878a:99) synonymized Quatrefages species with E.
torquata, also described by Quatrefages. This synonymy
appears unproblematic and is here accepted.

gave the Philippines (Bohol) as type locality; the specimens
described here are marked types in the collections of the Berlin
Museum. The large syntype is very soft and flabby; the small
syntype is in excellent condition and forms the base for the
re-description.
DESCRIPTION.—Large syntype incomplete, of unknown sex,
with 241 setigers; length 242 mm long. Small syntype
incomplete; with 80 setigers; length 55 mm; maximal width 5
mm; length through setiger 10, 10 mm.
Prostomium (Figure 31o) distinctly shorter than peristomium,
nearly as wide as peristomium, as deep as x li of
peristomium. Prostomial lobes frontally rounded, dorsally
inflated; median sulcus deep. Eyes not observed. Antennae in
transverse row, evenly spaced, similar in thickness. Ccratophores
ring-shaped in all antennae, without articulations. Ccratostyles
digitiform, with up to 5 long, indistinctly marked,
cylindrical articulations in A-III. A-I to middle of peristomium;
A-II to setiger 1; A-I 11 to setiger 2. Peristomium flaring
anteriorly; lower lip expanded into thick bolster-like structure,
wider than rest of peristomium. Separation between rings
distinctly dorsally and vcnirally; anterior ring 5 A of total
peristomial length. Peristomial cirri to middle of anterior
peristomial ring, digitiform, with 2 articulations.
Maxillary formula of large syntype 1+1, 4+4, 7+0, 5+8, and
1+1.
Branchiae (Figure 3In) present, pectinate, distinctly longer
than notopodial cirri, not reduced in mid-body region, erect.
Branchiae from setiger 6 to end of small syntype, to setiger 138
in large syntype, leaving about half of incomplete specimen
abranchiate. Branchiae terminating well before posterior end.
First branchia with 3 filaments; maximum 10 filaments at about
setiger 15. Number of filaments reduced from about setiger 30;
from about setiger 45 rest of branchial region with 1 or 2
filaments present. Stems longer than notopodial cirri, tapering,
erect Filaments longer than notopodial cirri, digitiform,
relatively slender.
Anterior neuropodial acicular lobes truncate with aciculae
emerging at superior corner; median and posterior acicular
lobes (Figure 31p) short, rounded. Pre- and postsetal lobes low,
transverse folds; postsetal lobes unusually low in relation to
acicular lobes. First 4-5 ventral cirri thick, tapering. Median
ventral cirri basally inflated from early branchial setigers;
narrow tips absent. Inflated bases nearly spherical in setigers
15-25, decreasing in size slowly posteriorly, developing a
broad transverse shape and eventually a dorsal depression. Far
posterior ventral cirri scoop-shaped, curving around emerging
subacicular hooks, relatively narrow, nearly digitiform in
anterior and posterior outline; narrow tips tapering. Anterior
notopodial cirri tapering, with 2 or 3 indistinct, cylindrical
articulations. Notopodial cirri loosing articulations, becoming
shorter and more distinctly tapering from branchial region,
retaining that shape to last segments.
Limbate setae slender. Anterior pectinate setae (Figure 31i)
