Uneroded animals with a pattern of longitudinal undulated lines, and with fine brownish lines along the growth ridges. Jugal area wedge-shaped, generally white with a smaller, darker triangle within. Dorsally the animal is slightly subcarinated. Dorsal elevation of valve iv 0.38 ( +5.2 mm +high/ +13.6 mm +wide) in a specimen (29.7 × +15.4 mm +) from Pointe Autea. + +Large ocelli present in head valve, lateral areas and postmucronal area, with a diameter of 38 µm, surrounded by small apical pores with caps 14 µm in diameter. Subsidiary pores occur randomly around the other pores, with highest concentration around ocelli. Head valve semicircular with posterior margin straight and unnotched. Intermediate valves (excluding the second) wider than long with protruring apex. Second valve largest. Lateral areas slightly elevated and clearly separated from central areas by sculpture. Fine, comarginally directed, wavy growth ridges also occur along part of the diagonal ridge in the pleural areas. General tegmentum surface smooth, except for the growth ridges and pits in the jugal-pleural areas. Sculpture of lateral areas homologous with that of head valve and postmucronal area.Tail valve triangular, width more than twice length; mucro terminal, slightly elevated, forward-directed. Postmucronal slope steep and very short. + +Articulamentum thick, shiny, with dark brown coloration in central area and white margins.Apophyses wide, long, triangular in valve ii to trapezoidal in tail valve, widely separated but connected by a short lamina, which shows minute teeth. Slits between them correspond to rows of transverse holes. Insertion plates rather short, with long, sharp, sawed teeth, roughly pectinate on outside. Slit formula: 8/1-1/0 (callus). Slitrays present in all valves, except for tail valve.They consist of transverse to round (innermost) holes. Callus with series of large transverse holes on its inner side. +A +very conspicuous thickening of the articulamentum results in two diagonal bridges. + +Cuticle of perinotum thick, dorsally beset with very fine spicules (121-147.4 µm × 47-53 µm), giving the whole girdle a velvety appearance. Spicules sculptured with about nine longitudinal ribs, which are less distinct in the basal part. Among the spicules, smooth, sharp-pointed needles were found, 95 × 16 µm in size. Ventrally there are radial rows of squarish to rectangular scales, measuring 24-30 µm. They are obtusely pointed and a little concave.There are about 7-10 shallow, longitudinal grooves on their visible side. + + +FIG. 8. — + +Onithochiton lyellii +(Sowerby,1832) + +,specimen,Rapa Island, +RAPA +2002,stn 80, +17.4 mm +: + +A + +, head valve dorsal view; + +B + +, valve ii, dorsal view; +C +, valve ii, left side, ventral view, detail of slit; +D +, valve ii, detail of sutural laminae, ventral view; + +E + +, tail valve, dorsal view; +F +, tail valve, lateral view.
