Additional material. Chone aurantiaca ( Johnson, 1901)   [ MCZ 1933, holotype]. Chone magna ( Moore, 1923)   [ USNM 17281, holotype]. Chone picta ( Verrill, 1885)   [ YPM 30000 View Materials , topotypes]. Chone veleronis Branchial   lobes and branchial crown. Insertion of the branchial crown exposed dorsally beyond collar ( Fig. 6 View FIGURE 6 A). Radioles: 12–22 pairs. Radioles with median pinnules slightly longer than proximal pinnules. Radiolar tips long. The palmate membrane (pm) extends about three quarters the length of the branchial crown ( Figs 6 View FIGURE 6 E, J). Lateral flanges (fl) broad ( Fig. 6 View FIGURE 6 J). Dorsal lips broadly rounded in frontal view, as long as wide, without mid-rib, resembling the ventral lips, longer than wide in dorso-lateral view. Dorsal pinnular appendages (dpa): 1–4 short pairs united by a palmate membrane ( Fig. 6 View FIGURE 6 K). Ventral lips rounded, as long as wide, about one quarter the length of the dorsal lips. Ventral radiolar appendages: 1–2 pairs, short, as long as basal pinnules of the ventral most radiole.

Peristomium   . Anterior peristomial ring lobe (aprl) not exposed beyond collar, distally entire, triangular ( Fig. 6 View FIGURE 6 B). Posterior peristomial ring collar: antero-dorsal ( Fig. 6 View FIGURE 6 A), ventral and lateral margins entire ( Figs 6 View FIGURE 6 B, E), ventral margin higher than dorsal ( Fig. 6 View FIGURE 6 B); longitudinal grooves on dorsal, ventral and lateral sides of collar; entire length of mid-dorsal collar margins forms a broad gap. Dorsal pockets well developed. Ventral shield of collar rounded ( Fig. 6 View FIGURE 6 E) (not easily discernible). Ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view: 2: 1.

Thorax. Chaetigers 2 to 8: notopodia– two irregular rows of elongate, narrowly hooded chaetae ( Fig. 6 View FIGURE 6 I); one anterior row with narrow bayonet chaetae ( Fig. 6 View FIGURE 6 G); two posterior rows with symmetrical; paleate chaetae with a short mucro ( Fig. 6 View FIGURE 6 H); neuropodia– two irregular rows of acicular uncini per torus ( Fig. 6 View FIGURE 6 F), second tooth enlarged, located in the midline, dentition covering one quarter of the main fang length. Glandular ridge on chaetiger 2 narrow.

Abdomen. Abdominal segments: 68–74. Anterior ( Fig. 6 View FIGURE 6 C) and posterior uncini ( Fig. 6 View FIGURE 6 D) similar, with the main fang surmounted by four rows of teeth equal in size, occupying less than half the length of main fang, main fang not extending beyond breast, breast rectangular. Pygidium with rounded posterior margin.

Methyl green staining. Body stains uniformly, except for the anterior margin of collar ( Figs 6 View FIGURE 6 A–B, E).

Remarks. In C. fauveli   , C. aurantiaca   , C. magna   , C. picta   and C. veleronis   , the ventral margin of collar is higher than dorsal margin, and the ratio of posterior peristomial ring collar length versus chaetiger 2 length, in lateral view is 2: 1. Chone fauveli   and C. veleronis   have broad flanges and radiolar tips long, but the glandular ridge on chaetiger 2 is rounded in C. fauveli   and sunglasses-shaped extending to the first half of the third segment in C. veleronis   . The mucro of the paleate chaetae in C. fauveli   is short while it’s missing in C. magna   and C. picta   , and minute, hair-like in C. aurantiaca   . Among species of Chone   included in this revision, C. fauveli   is unique by having a rounded ventral shield of collar ( Table 2 View TABLE 2 ).

Material examined. Type material. Chone infundibuliformis Kr ø   yer, 1856 [ ZMUC POL – 1749, lectotype], [ USNM 376, paralectotype], [ BMNH 82.5. 12.33, paralectotype]. Chone suspecta Kr   ø yer, 1856 [ ZMUC POL – 1748, holotype, Kristianssund, Norway].

Observations on C. suspecta   holotype. Specimen with histolysis, no branchial crown is preserved. Body length 11 mm, width 1.5 mm. Thoracic uncini with four rows of teeth above the main fang ( Fig. 7 View FIGURE 7 A); paleate chaetae with medium-sized mucro ( Fig. 7 View FIGURE 7 B); narrowly hooded bayonet chaeta ( Fig. 7 View FIGURE 7 D); anterior abdominal uncini with squared breast ( Figs 7 View FIGURE 7 E–G). Abdominal segments: 42. Spermatozoa with barrel-shaped nucleus; triangular, small acrosome and two small rounded mitochondria ( Fig. 7 View FIGURE 7 C).

Remarks. Kr ø yer (1956) described Chone suspecta   on the basis of a single specimen with damaged radioles. Malmgren (1866: 404) referred C. suspecta   to C. infundibuliformis   . Cochrane (2000) stated that the etymology suggested his uncertainty as to whether the specimen was representative of a discrete taxon or a juvenile form of C. infundibuliformis   . This study confirms that C. infundibuliformis Kr   ø yer, 1856 is a synonym of C. suspecta Kr   ø yer, 1856. The name infundibuliformis   has priority over suspecta   and has been in frequent use since its inception and is the name used by most museum curators (Art. 23.1, International Code of Zoological Nomenclature, 2000).
