Not Eulepis geayi.—Fauvel, 1940, p. 9 (=Grubeulepis augeneri, new species).—Tebble, 1955, p. 79 (=Grubeulepis tebblei, new species).

MATERIAL EXAMINED.—Delagoa Bay, Inhaca Island, southeast Africa, intertidal—1 specimen (BMNH 1952: 1: 2: 1).

DESCRIPTION.—Length 35 mm (21-40 mm), width, including setae, 8 mm (5-8 mm), segments 39 (36-39). Elytra 12 pairs, becoming more elongate posteriorly; first pair (missing on specimen examined) with 3-4 papillae on anterior margin (Day, 1967); remaining elytra with variable number lateral leaflike processes between anterior and posterior rounded lobes [for example, 3 on second, 8 on eighth, and 17 (left) and 21 (right) on twelfth)]; processes digitiform, not articulate (Figure 20d-f). Branchiae 13 pairs, inflated, with distal branchial cirrus (Figure 19b). Dorsal cirri on segments 3 and 6, subulate (Figure 18b). Posterior lamellae, beginning on segment 28, subreniform to subconical (Figure 20a).

Prostomium covered by segment II, attached middorsally on posterior half; median antenna short, conical, inserted anterodorsally on prostomium; lateral antennae conical, inserted more ventrally; palps elongate-tapered, extending beyond tentacular cirri; no eyes visible; nuchal organs clavate, lateral to prostomium (Figure 18a). Tentacular parapodia (I) narrower basally, enlarged distally, each with dorsal and ventral tentacular cirri, subequal in length, 2 acicula and 2 bundles of smooth and spinous capillary setae. Ventral buccal cirri on segment II thicker and longer than those following.

Biramous parapodia supported by reddish amber-colored acicula and neuropodial hammer-shaped distal plates (Figures 19a,b; 20a). Notopodial acicula with hooked tips. Notopodial capillary setae smooth and spinous, forming long spreading bundles emerging from posterior parts of notopodia; stout reddish amber-colored notopodial hooked setae, spinous along bend and distal part, tapering

distally to fine tips or flattened spatulate (Figure 19c). Neuropodial acicula with hammer-shaped distal plates. Neurosetae of several kinds: 1-2 upper pectinate setae (Figure 19d); limbate capillaries (Figure 18c,e); slender setae, tapering gradually to long capillary tips (Figure 19f); slightly stouter setae tapering rather abruptly to capillary tips (Figure 19e); few stout acicular neurosetae in some anterior segments (Figure 18d). In posterior region, some of upper neurosetae much stouter than lower neurosetae, bent downward, tapering abruptly to fine tips (Figure 20a-c). Pygidium with single long anal cirrus on right side; left cirrus short, bulbous. Pharynx not extended.

DISTRIBUTION.—Indo-west-Padfic (Madagascar, Mozambique, Natal), Red Sea, South-west-Pacific (New Caledonia). Intertidal. May be commensal with Polyodontes melanotus, according to Day (1962).
