SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
FIGURE 33.—Eunice collaris (holotype, ZMB F500): a, anterior end, lateral view; b, subacicular hook,
parapodium 49; c, subacicular hook, parapodium 51; d, compound falciger, parapodium 51; e, pectinate seta,
parapodium 51; f, parapodium 51, anterior view. (Scale bars in mm.)
Proximal teeth narrow, directed basally, distal teeth distally
blunt, curved. Guards symmetrically bluntly pointed, marginally
serrated, without mucros. Pseudocompound falcigers and
compound spinigers absent. Aciculae single, dark brown,
bluntly pointed and straight; cross-section round. Subacicular
hooks (Figure 33cb,c) brown, bidentate. Hooks first present
from setiger 27 or 33, present in all setigers thereafter, always
single (except for replacements). Hooks abruptly tapered, with
distinct head at right angles to long axis. Proximal teeth very
large, blunt; distal teeth short and rounded.
UNKNOWN MORPHOLOGICAL FEATURES.—Jaw structure;
pygidium and anal cirri.
EXPECTED STATES OF UNKNOWN MORPHOLOGICAL FEA-
TURES.—Mx III short, forming part of distal arc with left Mx II.
CHARACTERS USED IN PREPARATION OF KEY NOT
SCORED.—Inappropriate Characters: 56, 58, 59. Unknown
Characters: 1,2,15, 37, 38, 40,47, 50, 63, 74, 78.
ASSUMED STATES FOR PURPOSE OF PREPARING KEY.—37,1;
38,1.
REMARKS.—Two additional syntypes differ at the species
level from those listed above and are here referred to E. afra.
Eunice collaris has been considered a synonym of E. afra since
Crossland (1904:289) first referred it to that species. As
indicated above, the type material contains two species, both of
