About 5.5 whorls, smooth and, lightly polished, growth lines present which are raised slightly at the suture; teleoconch with 4.5-5.5 whorls. Suture simple. : imperforate. Columella curved, somewhat thickened, slightly reflected,white, with a thin callus joining the lip and a small plication. Aperture roundly ovate, large, about 3/4 of the shells height.

Indo-West Pacific; Tarawa & Gilbert Islands [Smith, 1865:551]; Solomon Islands, New Zealand, NSW, Queensland, NSW, Tasmania, as well as wetsern and northern Australia; central Japan;Korean Peninsular [NIBR, 2019:328] ; Persian Gulf [Petit de la Saussaye, 1853: 118]; Red Sea [Beu, 2017:206]; Eastern Pacific, Easter Island [Rehder, 1980:53]; entire Gulf of Mexico, East Florida to Brazil [Rosenberg et al, 2009:643]; Brazil [Rios, 1985:160]; Natal to Cape Town, South Africa [Barnard, 1963:108].
Habitat:
pelargic.
Etymology:
[latin] from luteus = yellow or golden yellow, in reference to the colour of the shell.

ranslation: "Shell ovate, very thin, imperforate, dirty white beneath a thin brownish epidermis; five inflated whorls, although somewhat less detached than in the following species; the spiral striae are almost obsolete and very narrow on the upper whorls, and resemble grooves on the last whorl. Suture very narrow; spire conical, about one-third shorter than the aperture; aperture ovately rounded; inner lip slightly concave in the middle, and almost straight below the sinuosity; outer lip semicircular and very thin."
This shell was found in the open sea in the Arabian Gulf by Commander Jehenne, who, as noted above, had preserved the vesicular appendage by means of which the mollusc floated on the surface of the water.

Translation: Recluzia rollandiana nobis (pl. 5, fig. 12)
Shell ovate-oblong, subperforate, whitish-brown beneath a slightly tawny epidermis; with six very inflated whorls, sculptured with transverse striae, some deeply impressed and others obsolete; suture deep; spire conical and elevated; aperture ovate; columella slightly sinuous in the middle, becoming nearly straight below; outer lip semi-ovate and thin.
Length 25 mm; width 18 mm.
"Shell ovate-oblong, brownish-white beneath a slightly tawny epidermis; six very inflated whorls, sculptured with striae, some rather deeply impressed and others only faintly marked; the whorls are separated by a deep suture. Spire conical, almost equal in length to the aperture; aperture ovate; columella with a slight sinus in the middle, and behind this sinus a kind of small perforation; the lower portion of the columellar lip runs almost straight, except where it joins the outer lip; outer lip semi-oval and thin."
This species differs from the preceding one in being more elongate, with more rounded whorls separated by a much deeper suture. Its transverse striae are also more strongly developed. The difference in habitat further justifies the distinction made between these two species.
Recluzia rollandiana comes from the Atlantic Ocean, in the vicinity of Mazatlán. The specimen used for this description belongs to M. Rolland du Roquan, who kindly placed it at the author's disposal, and to whom the species is dedicated in gratitude for his courtesy.
