85.  Mitra tabanula ?  Lam.  Hist. 7 323. n. 79.

A single bleached specimen, agreeing with this description excepting in having five instead of three or four plaits on the columella, was brought up by the sounding line.  The shell is longitudinally grooved, and very remarkable for being furnished with numerous, rather distant, smooth, narrow, raised spiral bands; having the inter-spaces finely spirally striated; the nucleus of the shell, like that of a voluta, is mammillary.

Lamarck never having seen this shell has described it on the authority of Chemnitz, whose figure agrees very well with the shell before me; excepting that the spots round the suture form nearly a continual band at a little distance from it; the outer lip is smooth and thin; the inside dull livid brown; the axis is fourteen-twelfths, the diameter seven-twelfths, of an inch.

87.  Marginella minuta (n.s.) Testa minuta ovata fusiformis alba polita, spira conoidea obtusiuscula, labro inflexo, columella quadriplicata.  Icon. —­

Shell ovate, fusiform, white, polished; spire conical, nearly as long as the aperture, rather blunt; outer lip somewhat inflexed; columella with four distinct plaits; axis three-twelfths, diameter two-twelfths of an inch.

90.  Strombus australis (n.s.)

Testa ovato-oblonga tuberculata spiraliter sulcata albida fusco-variegata, spira exserta, cauda recurva, labro incrassato posterius lobo digiti-formi termitato intus (roseo ?) sulcato.  Icon. —­ ?

Shell ovate oblong, spiral, white, spotted and lined with pale, fulvous-brown; the spire exserted, conical, half as long as the shell; the whorls longitudinally ribbed with one more prominent than the rest, the one nearest the suture being acute and tuberculated; the canal recurved; the outer lip thickened, ending in a projecting lobe behind, and edged with two or three blunt tubercles; the throat rose-coloured, furrowed; the inner lip much thickened.

This shell is one of the five species which have been confounded with Strombus auris dianae; it is most like S. zelandiae, n.  Chemn. 10 t. 156. f. 1485, 1486, in form and throat, but has the sculpture of S. adusta, n.  Chemn. 10 t. 156. f. 1487, 1488; this last Lamarck considers as the true S. auris dianae, whilst Linnaeus unquestionably describes the shell figured by Martini, 7 t. 84. f. 840, and by Seba, 3 t, 61. f. 1, 2, which I have named S. lamarckii, from having considered it to be the young of a new species; it is figured by Martini, 7 t. 84. f. 338, 339, and by Seba, 3 t. 61. f. 5, 6, and is very nearly allied to S. bituberculatus of Lamarck.
