description: <i>Rapa rapa</i> (Linné, 1758) Figs 123, 124, 192 <i>Murex rapa</i> Linné, 1758: 752, no. 476. Synonyms: <i>Rapa pellucida</i> Röding, 1798: 148. <i>Rapa striata</i> Röding, 1798: 148. <i>Pyrula papyracea</i> Lamarck, 1816: pl. 436. TYPE MATERIAL. — <i>Murex rapa</i>: not found — <i>Rapa pellucida</i>: unknown. — <i>Rapa striata</i>: unknown. — <i>Pyrula papyracea</i>: three lots in the Lamarck collection at MHNG, although none of them is labeled as type material, and their status is doubtful (Y. Finet, pers. comm.): 1098/59 (1 specimen, 65.6 mm), 1098/60 (3 specimens, 40.6, 38.4 and 36.2 mm), 1098/61 (1 specimen, 55.0 mm). TYPE LOCALITY. — <i>M. rapa</i>: undetermined (“In Oceano Asiatico”). — <i>R. pellucida</i>: undetermined. — <i>R. striata</i>: undetermined. — <i>P. papyracea</i>: two of the specimens in MHNG (1098/59, 1098/61) are labelled “Oc. indien”. MATERIAL EXAMINED. — <b>New Caledonia proper</b>. LAGON: EXPÉDITION MONTROUZIER: stn 1245, Secteur de Touho, stn 912, Secteur de Koumac, 20°57’S, 164°53’E, 8-12 m, 1 lv 20°45.2’S, 165°16.3’E, intertidal, 1 dd (Fig. 124). (Figs 123, 192) and 1 fragment (including the protoconch). — <b>FIGS 123-126</b>. Teleoconchs of <i>Rapa</i>. <b>123</b>, <b>124</b>, <i>R. rapa</i> (Linné, 1758). <b>123</b>, LAGON: stn 912, H 25.6 mm; <b>124</b>, EXPÉDITION MONTROUZIER stn 1245, H 33.6 mm. <b>125</b>, <i>R. incurva</i> (Dunker, 1852), LAGON stn 269, H 27.6 mm; <b>126</b>, LIFOU 2000 stn 1447, H 24.1 mm. DISTRIBUTION. — Indian Ocean: Seychelles (Jarrett 2000). West Pacific, “completely embedded in soft, rubbery corals” (Cernohorsky 1972). New Caledonia, live in 8-12 m, empty shells from intertidal to 8 m. REMARKS. — The species included in <i>Rapa</i> are diagnosed on the basis of shell outline and sculpture and deserve a revision based on at least a careful anatomical analysis. The two specimens are here referred to <i>R. rapa</i> on the basis of the stronger spiral cords on the base (compared with <i>R. incurva</i> – see below). Protoconch of 3+ whorls (3.8 whorls in Philippine specimens: MO unpublished). Protoconch-I eroded in the available specimens, estimated of about 1 whorl. Protoconch-II of about 2.8 whorls, with 2 major spiral keels (the abapical starting on the early second protoconch whorl, the adapical starting at the end of the second protoconch whorl), and 1 minor subsutural keel, sculptured with a series of threads over each keel; the subsutural threads are prosocline, the median orthocline, the abapical opsthocline. The series of threads tend to fuse giving rise to sigmoid collabral riblets.
