SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY
FIGURE 27.—Eunice brevis (holotype of Nicidion brevis, MCZ 833): a, anterior end, lateral view; b, compound
falciger, parapodium 100; c, limbate seta, parapodium 100; d, subacicular hook, parapodium 100; e, pectinate
seta, parapodium 100; f, acicula, parapodium 100. (Scale bars in mm.)
articulated ceratostyles; in addition to E. brevis, these species
are E. curticirris and E. fuscafasciata. Eunice curticirris has
moniliform articulations; the other two species have cylindrical
articulations. In E. brevis the inflated bases of median ventral
cirri forms thick, transverse welts; in E. fuscafasciata, they are
ovate.

Eunice afra.—Hartman, 1956:282 [in part, not Eunice afra Peters, 1854].
MATERIAL EXAMINED.—Holotype, AMNH IV-1918-1286,
Buccoo Bay, Tobago Island, Mar 1918.
COMMENTS ON MATERIAL EXAMINED.—The anterior end
had been deeply dissected and the illustration is somewhat
distorted; especially, the lower lip may be expanded over the
normal condition.
DESCRIPTION.—Holotype incomplete, currently in 3 pieces,
with a total of 226 setigers; anterior fragment with 66 setigers;
length 41 mm; maximal width 3.5 mm at about setiger 15.
Length through setiger 10, 7.5 mm; width at setiger 10, 3.25
mm. Body anteriorly cylindrical, becoming dorsoventrally
flattened, truncate anteriorly, tapering posteriorly.
Prostomium (Figure 28a) distinctly shorter and narrower
