FIGURE 53.—Eunice guildingi (holotype, BM(NH) 1839.12.27.5): a, anterior end, lateral view; b, subacicular
hook, parapodium 37; c, compound falciger, parapodium 37; d, pectinate seU, parapodium 37; e, parapodium 37,
anterior view. Eunice guttata (holotype, BM(NH) ZB 1972.71): f, anterior end, lateral view; g, parapodium 34,
anterior view; h, compound falciger, parapodium 34; i, pectinate seta, parapodium 34; j, subacicular hook,
parapodium 34. (Scale bars in mm.)
aciculae emerging above midline. Presetal lobes low, transverse
folds. Anterior postsetal lobes following outline of
acicular lobes closely, becoming low transverse folds in
median and posterior setigers. First 4 ventral cirri tapering.
Ventral cirri basally inflated from about setiger 5 through
remainder of body. Bases ovate, narrow tips tapering. Anterior
notopodial cirri digitiform, becoming slightly inflated medially
in anterior branchial segments. Notopodial cirri decreasing in
length from about setiger 5 to setiger 20, thereafter short,
slender, digitiform. Notopodial cirri without articulations.
Pectinate setae (Figure 53d) flat, flaring. One marginal tooth
distinctly longer than other teeth, with -10 coarse teeth. Shafts
of compound falcigers (Figure 53c) distally slightly inflated,
marginally frayed or serrated. Appendages short, tapering with
very large head, bidentate. Proximal teeth shorter than distal
teeth, tapering, directed obliquely distally. Distal teeth very
nearly erect, tapering. Guards symmetrically bluntly pointed,
marginally serrated; mucros absent. Pseudocompound falcigers
and compound spinigers absent Notopodia supported by
paired aciculae. Neuropodial aciculae single, black, tapering,
distally straight; cross-sections round. Subacicular hooks
(Figure 53b) black, bidentate. Hooks first present from setiger
