A Review of the Genus Eunice - Smithsonian Institution Libraries

NUMBER 523 279
18+0, 12+12, and 1+1. Mx III behind left Mx II. Both Mx IV
with same number of teeth. All teeth very small and even in
size.
Branchiae (Figure 93e) present, pectinate, distinctly shorter
than notopodial cirri, not reduced in mid-body region, flexible.
Branchiae from setiger 3 to end of body. Branchiae present to
near posterior end, present on more than 65% of total number
of setigers. First pair single filaments, all other branchiae with
at least 4 filaments; maximally 25 filaments from setiger 15 to
setiger 275; thereafter number slowly reduced; 15 filaments
present in last setigers. Branchial stem thick, folded over in
most parapodia. Filaments filiform.
Neuropodial acicular lobes asymmetrically rounded with
aciculae emerging on dorsal side. All presetal lobes obliquely
truncate. All postsetal lobes low, transverse folds. First 5 or 6
ventral cirri thick, digiliform. Ventral cirri basally inflated by
setigers 6-7; inflated bases retained through about setiger 250.
Inflated bases nearly spherical; narrow tips tapering. Far
posterior ventral cirri tapering. Notopodial cirri very long,
especially in anterior part of body. Where best developed, at
about setiger 100, longer than width of body, slender, tapering,
without articulations.
Limbate setae marginally smooth. Pectinate setae (Figure
93c) tapering, flat. One marginal tooth very much longer than
other teeth; 8 teeth present. Shafts of compound falcigers
(Figure 93b) slightly inflated, marginally smooth. Appendages
tapering, bidentate. Both teeth of same size, slender, tapering.
Proximal teeth directed distally; distal teeth gently curved.
Guards asymmetrically bluntly pointed; mucros absent. Pseudocompound
falcigers and compound spinigers absent. Most
aciculae in triplets, dark brown to black, with tapering slender
tips, straight; cross-section round. Separation between cores
and sheaths indistinct in both aciculae and subacicular hooks.
Subacicular hooks (Figure 93d) dark brown to black, bidentate.
Hooks first present from setiger 68 in holotype (from setigers
62-72 in paratypes), present in all setigers thereafter, always
single (except for replacements). Hooks slender, tapering to a
small head. Proximal teeth slightly larger than distal teeth; both
teeth directed distally.
UNKNOWN MORPHOLOGICAL FEATURES.—Pygidium
anal cirri.
EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA-
TURES.—None.
CHARACTERS USED IN PREPARATION OF KEY NOT
SCORED.—Inappropriate Characters: 56, 58, 59. Unknown
Characters: 1, 2,4, 6, 13, 14, 36.
ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—
None.
REMARKS.—Eunice pulvinopalpata is a member of group
B-2; however, it also resembles some of the deep-water
members of group A-1 and should be compared to these species
as well (Tables 19-21). It is branchiated to near the posterior
end, in contrast to most other deep-water species. It is listed
with similar species in group B-2 in Tables 27 and 31. The only
and
other species in Table 31 with more than 20 branchial filaments
is E. franklini. The branchial filaments in the latter are very
short and stubby; those in E. pulvinopalpata are slender,
digitiform and certainly not unusually short.
Eunice punctata (Risso, 1826)
Ltodice punclata Risso, 1826:421-422.
Eunice punctata.—Quatrefages, 1866:331.
REMARKS.—This species, of which no authoritative material
exists, was considered either indeterminable or doubtfully as a
member of Marphysafallax by Fauvel (1923:451). The species
described by Heider (1925) under this name cannot be a
Marphysa because it has peristomial cirri; it is here considered
as E. harassii. Eunice punctata (Risso) is indeterminable.
Eunice punclata Peters, 1854:611.
Eunice punctata Peters, 1854
REMARKS.—The specific name is preoccupied in the
combination E. punctata (Risso, 1826). Peters' species is
redescribed above as E. petersi.
Eunice punctata Grube, 1856
Eunice punctata Grube, 1856:59-60.
Eunice binominata Quatrefages, 1866:327.
REMARKS.—Quatrefages (1866:327) pointed out that
Grube's specific name was pre-occupied by Risso (1826);
Quatrefages apparently had overlooked Peters' use of the name,
issued two years before Grube *s paper, so the name was in fact
doubly pre-occupied by the time Quatrefages reviewed the
matter. Grube's species is here discussed as E. binominata.
164. Eunice purpurea Grube, 1866
FIGURE 94; TABLES 27,30
Eunice purpurea Grube, 1866b:68.
Eunice vlolacea.—Grube, 1861:60-61 [not Eunice violacea Grube, 1856].
MATERIAL EXAMINED.—Two syntypes, ZMB F 2012,
Portor6, Lesina, Adriatic Sea, coll. Grube.
COMMENTS ON MATERIAL EXAMINED.—The description is
based wholly on the large specimen; some notes on the small
specimen, which is a juvenile, have been appended. The
peristomium of the large specimen has been ventrally dissected
and the jaw apparatus torn partially loose; the illustration shows
the condition with the jaws tucked back into position, but is in
part a reconstruction where tissue had been removed.
DESCRIPTION.—Large syntype complete with 106 setigers;
total length 53 mm; maximal width 4 mm; length through
setiger 10, 9.5 mm. Other syntype with 40 setigers; length 7
mm long.
Prostomium (Figure 94a) distinctly shorter and narrower
