166 SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
remaining inflated through rest of body. Basal inflation very
large, nearly spherical, very small tapering tips present in all
setigers. Notopodial cirri basally inflated, distally tapering,
without articulations.
Limbate setae tapering, gently geniculate, frayed. Pectinate
setae (Figure 53i) numbering 5 or more in a fascicle. Shafts
wide, flat Blades tapering, flat. One marginal tooth clearly
longer than other teeth, with -14 teeth. Shafts of compound
falcigers (Figure 53h) distally inflated, marginally smooth.
Appendages very slender, tapering, with large heads, bidentate.
Proximal teeth about as large as distal teeth, sharply directed
laterally. Distal teeth flattened, nearly geniculate and directed
laterally. Guards asymmetrically bluntly pointed, marginally
smooth; mucros absent. Pseudocompound falcigers and compound
spinigers absent Aciculae numbering 1 to 3, dark,
tapering, straight; cross-sections round. Notopodial aciculae
paired, dark. Subacicular hooks (Figure 53j) dark, bidentate.
Hooks first present from setiger 32, present in all setigers
thereafter, paired in some setigers. Hooks smoothly tapering to
small head. Proximal teeth larger than distal teeth; both teeth
directed obliquely distally. Guards short and blunt.
UNKNOWN MORPHOLOGICAL FEATURES.—Jaw structure;
pygidium and anal cirri.
EXPECTED STATES OF SELECTED UNKNOWN FEATURES —
Mx III short and forming part of distal arc with left Mx IV.
CHARACTERS USED IN PREPARATION OF KEY NOT
SCORED.—Inappropriate Characters: 22, 56, 60. Unknown
Characters: 13, 14, 39,40,42, 74, 78.
ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—
None.
REMARKS.—The specimen may have been highly colored; a
ghost of dark pigmentation remains. The specimen may have
been dark brown or red, with white circular spots scattered
densely over the anterior end. A white band may have been
present.
As far as known, this species has never been reported since
it was briefly described by Baird (1869); it belongs to group
B-2 and is listed with similar species in Tables 27 and 28. It is
the only species, other than E. aphroditois, listed in Table 28
that has the ventral cirri basally inflated through the posterior
end. It differs from that species mainly in that it has far fewer
branchial filaments and in the proportions of the prostomium.
Nothing is known about its habitat other than that it was
collected somewhere in the Indian Ocean/Indonesian region,
presumably in shallow water.

MATERIAL EXAMINED.—One specimen, MNHN, Paris
A.l(R.)-1868-no. 46a. lies Chausey, Quatrefages.
COMMENTS ON MATERIAL EXAMINED.—The type has been
lost; justification for using the current specimen to represent the
species is given below. The jaws are half everted and the
maxillary formula given is incomplete because detailing the
formula would destroy the jaws completely.
DESCRIPTION.—Specimen incomplete, of unknown sex,
with 63 setigers; length 22 mm; maximal width 2.5 mm at
setiger 10; length through setiger 10, 5 mm. Body cylindrical.
Prostomium less than x li as thick as peristomium, narrow.
Prostomium (Figure 54a) distinctly shorter and narrower than
peristomium, less than x li as deep as peristomium. Prostomial
lobes frontally obliquely truncate, dorsally flattened; median
sulcus deep. Eyes at bases of A-I, faded. Antennae in shallow
horseshoe, evenly spaced, similar in thickness. Ccratophorcs
ring-shaped in all antennae, without articulations. Ceratostyles
tapering, with up to 5 indistinct, cylindrical articulations in
A-I 11. A-I to posterior pcristomial ring; A-I I to setiger 2; A-I 11
to setiger 4. Peristomium cylindrical. Separation between rings
distinct on all sides; anterior ring 4 /s of total pcristomial length.
Pcristomial cirri to middle of anterior pcristomial ring, slender
and tapering, without articulations.
Incomplete maxillary formula 1 + 1, +, 6+0, 3+8, 1+1. Mx
VI missing. Mx III long, but part of distal arc with left Mx IV.
Branchiae (Figure 54d) present, pectinate, distinctly longer
than notopodial cirri, not reduced in mid-body region, erect.
Branchiae from setiger 4 to end of fragment. First 3 branchiae
single filaments; all others pectinate with maximally 10
filaments at about setiger 15; last branchia present, on setiger
63, with 2 filaments only. Stems tapering, shorter than
notopodial cirri. Filaments long, digitiform, as long as
notopodial cirri where best developed.
Anterior neuropodial acicular lobes truncate; posterior
acicular lobes triangular; aciculae emerging at midline. Pre-and
postsetal lobes low, transverse folds. First 5 ventral cirri thick,
tapering. Ventral cirri basally inflated from setiger 6 through
about setiger 35; inflated base ovate; narrow lips tapering.
Posterior ventral cirri broadly transversely attached; enfolding
lower edge of parapodia, nearly scoop-shaped. Anterior
notopodial cirri basally slightly inflated, retaining same size in
all setigers, but less distinctly inflated in posterior setigers,
without articulations.
Limbate setae slender, marginally smooth. Pectinate setae
tapering, flat. One marginal tooth longer than other teeth, with
-12 teeth. Shafts of compound falcigers (Figure 54c) distally
tapering, marginally smooth. Appendages relatively short,
tapering with large, distinct heads, bidentate. Proximal teeth as
large as distal teeth, triangular, directed laterally. Distal teeth
distinctly bent, sharply tapering. Guards asymmetrically
bluntly pointed, marginally smooth; mucros absent. Pseudocompound
falcigers and compound spinigers absent. Aciculae
paired; anterior aciculae honey colored, becoming darker
brown in posterior setigers, distally tapering to sharp points,
