A Review of the Genus Eunice - Smithsonian Institution Libraries

NUMBER 523 167
FIGURE 54.—Eunice harassii (MNHN, Paris, A.l(R.)-1868-no. 46a): a, anterior end, lateral view; b, subacicular
hook, parapodium 46; c, compound falciger, parapodium 46; d, parapodium 46, anterior view. Eunice havaica
(syntype, RM 430): e, appendage of compound falciger, median parapodium; f, compound falciger, median
parapodium; g, subacicular hook, median parapodium; h, anterior end, lateral view. (Scale bars in mm.)
straight; cross-sections round. Separation between core and
sheath indistinct in both aciculae and subacicular hooks.
Subacicular hooks (Figure 54b) light brown, bidentate. Hooks
first present from setiger 28, present in all setigers thereafter,
always single (except for replacements). Hooks with distinct
neck. Proximal teeth large, curved, directed laterally. Distal
teeth bluntly triangular, nearly erect.

REMARKS.—Eunice harassii was described from lies
Chausey and St. Malo. Audouin and Milne Edwards
(1833:215) mentioned that the species was relatively common
in these areas. Quatrefages (1866:309) mentioned that he
described the species based on a specimen reported from lies
Chausey by Audouin and Milne Edwards. The specimen
described above appears to be the specimen used by Quatrefages
(1866) in his review and thus potentially part of the
original material. At the very least, the specimen comes from
one of the two type areas and may be part of the type material.
It is here considered an authoritative specimen, but not as a
type.
Heider (1925) gave an excellent description of the anatomy
of the anterior end of a species he called E. punctata (Risso,
