A Review of the Genus Eunice - Smithsonian Institution Libraries

200 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
Notopodial cirri very slender, very long, nearly whip-like,
longer than branchiae, with 5 or more long, slender articulations.
Limbate setae slender, marginally smooth. Shafts of pectinate
setae (Figure 66e) wide flat. Blades tapering, flat. One
marginal tooth longer than other teeth, with -10 teeth. Shafts of
compound falcigers (Figure 66b,c) slightly inflated, marginally
serrated when not worn. Appendages thick, tapering, bidentate.
Proximal teeth shorter than distal teeth, tapering, directed
laterally. Distal teeth distinctly thicker than proximal teeth,
bent, tapering. Many appendages with both teeth distinctly
worn, rounded or truncated. Guards asymmetrically bluntly
pointed, marginally serrated; mucros absent. Pseudocompound
falcigers and compound spinigers absent. Aciculac paired,
chestnut-colored without distinction between cores and
sheaths, tapering, straight in anterior and median setigers,
becoming bent ventrally in posterior setigers; cross-sections
round. Subacicular hooks (Figure 660 w 'th chestnut-colored
cores and clear sheaths, bidentate. Hooks first present from
setiger 30, present in all setigers thereafter, always single
(except for replacements). Hooks tapering, with distinct heads.
Proximal teeth larger than distal teeth, slender, directed
laterally. Distal teeth blunt, nearly erect.
UNKNOWN MORPHOLOGICAL FEATURES.—All features associated
with far posterior setigers; pygidium and anal cirri.
EXPECTED STATES OF SELECTED UNKNOWN FEATURES.—
None.
CHARACTERS USED IN PREPARATION OF KEY NOT
SCORED.—Inappropriate Characters: 56, 58, 59. Unknown
Characters: 1, 2,4,6, 23, 33, 36-40,47, 50,63.
ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—33,2;
37,1; 38,1.
REMARKS.—Eunice longicirris belongs to group B-2; it is
listed with similar species in Tables 27 and 32. It is primarily
characterized by the very long, slender, articulated notopodial
cirri and peristomial cirri. It is the only species listed in Table
32 in which the peristomial cirri clearly outreach the
prostomium.
Eunice longicornis Grube, 1866
Eunice longicornis Grube, 1866b:68.
Eunice longicirris.—Grube, 1878b: 100 [bottom of page, not Eunice longicirris
Grube, 1869:492].
REMARKS.—This species was described with branchiae from
setiger 6 to the end of the incomplete specimen (145+ setigers),
where best developed 23 filaments were present, and even in
the last setiger 19 filaments were present. A-III reached
segment 7; all antennae and peristomial cirri without articulations.
The branchiae outreach the notopodial cirri by setiger 12.
Through a lapsus, this species was referred to as E.
longicirris in a tabular review of the genus issued by Grube
(1878b: 100); however, on the same page is also mentioned the
very different species described as E. longicirris by Grube in
1869 and redescribed, based on the type above.
No material is available of E. longicornis and the original
description is insufficient to characterize the species; it is here
considered indeterminable.
Eunice longiqua Kinberg, 1865
Eunice longiqua Kinberg, 1865:563.
Eunice antennaia.—Hartman, 1948:78-79 [in part, not Lamarck, 1818].
REMARKS.—The single specimen reported by Harunan
(1948:78) is no longer present in the collections of Riksmuseet,
Stockholm (R. OlertJd, in litL). The available information,
summarized from Kinberg (1865) and Hartman (1948), is given
below.
Antennae, peristomial cirri, and notopodial cirri with
moniliform articulations. A-III to setiger 5; with 20 articulations.
Branchiae from setiger 6 to end of body; median region
with lowered number of branchial filaments. Aciculac yellow;
tapering with blunt, straight or gently curved tips. Subacicular
hooks yellow; tridentate. Compound hooks distally bidentate.
Eunice longiqua was reported from Foua in the Pacific
Ocean. It belongs to group C-2. Without access to any material,
the species cannot be separated from a series of similar species
and it is here considered indeterminable.

MATERIAL EXAMINED.—Holotype and 4 slides of parapodia,
USNM 4791, Bermuda, coll. G. Brown Goode, 1876.
DESCRIPTION.—Holotype complete, of unknown sex, with
108 setigers; length 40 mm; maximal width 3.5 mm; length
through setiger 10,6.5 mm. Body thickset, cylindrical, tapering
posteriorly, vaguely dorsoventral flattened.
Prostomium (Figure 66g) distinctly shorter and narrower
than peristomium, as deep as x li of peristomium. Prostomial
lobes frontally rounded, dorsally depressed and flattened;
median sulcus shallow. Eyes between bases of A-I and A-II,
purple. Antennae in horseshoe, evenly spaced, with A-I thicker
than other antennae. Ceratophores ring-shaped in all antennae,
without articulations. Ceratostyles thick and digitiform, with up
to 10 distinct, cylindrical articulations in A-II. A-I to middle of
anterior peristomial ring; A-II to setiger 4; A-III incomplete, at
least as long as A-II judging from its girth. Peristomium
cylindrical. Separation between rings distinct dorsally and
ventrally; anterior ring 5 /« of total peristomial length. Peristomial
cirri to middle of anterior peristomial ring, digitiform,
with 2 cylindrical articulations.
Jaws not examined.
Branchiae (Figure 661) present, pectinate, distinctly longer
than notopodial cirri, not reduced in mid-body region, erect.
Branchiae from setiger 6 to setiger 104. Branchiae present to
