SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
FIGURE 25.—Eunice bottae (type, MNHN, Paris, A.l(R.)-1868-no. 55b): a, anterior end, lateral view; b,
compound falciger, parapodium 28; c, subacicular hook, parapodium 28; d, aciculae, parapodium 28; e,
parapodium 28, anterior view. (Scale bars in mm.)
A-I to second peristomial ring; A-II to setiger 4 and A-III to
setiger 3. Peristomium cylindrical with flaring lower lip.
Separation between rings distinct dorsally and ventrally;
anterior ring 5 /6 of total peristomial length. Peristomial cirri to
middle of first peristomial ring, tapering, with 4 long,
cylindrical articulations.
Jaws not examined.
Branchiae (Figure 24e) present, pectinate, distinctly longer
than notopodial cirri, erect. Branchiae from setiger 6 to end of
fragment. First and last branchiae with 3 filaments; maximum
number of filaments 8 by setiger 15. Filaments shorter than
notopodial cirri. Branchial stems slender, erect, tapering, longer
than filaments. Filaments digitiform.
All neuropodial acicular lobes distally asymmetrically
truncate or rounded with aciculae emerging above midline. All
pre- and postsetal lobes low folds. Anterior and posterior
ventral cirri thick, tapering. Median ventral cirri distinctly,
nearly spherically basally inflated, with long, distally truncate
narrow tips. Notopodial cirri distinctly basally inflated in
anterior and early median setigcrs, becoming tapering and
slender towards the posterior end. All notopodial cirri with 4 or
5 long, cylindrical articulations.
Limbate setae longer than other setae, marginally serrated.
Pectinate setae present, but not observed in detail. Shafts of
