ART. XXXV.-Descriptions of New Species of New Zealand

Mollusca.

By HENRY SUTER.

[Read before the Wellington Philosophical Society, 2nd October, 1907.] Plates XXVIII-XXX.

1. Tonicia cuneata, n. sp. Plate XXVIII, figs. 1-2. SHELL oblong-ovate, rather small, valves much raised, the intermediate valves beaked, angled above, with cuneiform sculpture. Anterior valve with 4 low and smooth ridges with serrated margins, corresponding with the slits, anterior margin with the same number of slightly projecting lobes, posterior margin a little concave; sculpture between the riblets consisting of deeply engraved grooves and punctures, leaving numerous wedge-shaped patches of various size; the whole surface dotted with minute eyes. Of the intermediate valves, the first is notably larger than the following 5, all are sinuated on the latero-anterior sides and narrowed, convex in front and prominently beaked behind; dorsal area V-shaped, smooth, microscopically transversely finely striate; pleural tracts with a few narrow longitudinal and divergent serrated grooves; lateral areas not raised, with an anterior obtuse diagonal ridge, sculpture similar to that of the head-valve; the small, reddish eyes scattered over the whole surface. Posterior valve with a V-shaped dorsal area, its sides serrated, mucro at about the posterior fourth, posterior slope moderately concave, posterior margin slightly lobed, the lobes corresponding with the slits; sculpture beautifully wedge-shaped, with the posterolateral ridges corresponding with the anterior slits; the whole surface covered with minute eyes. Girdle moderately broad, leathery, yellowish, almost naked, with very few silvery fine hairs near the margin. Colour a dirty-white; anterior valve with the riblets reddish-white, the grooves and punctures rusty; intermediate valves with the central area light-olive, bordered by white, ornamented with very fine longitudinal reddish lines; grooves on the pleural and lateral areas rusty, a few light-blue spots scattered over the areas; posterior valve having the central area coloured as the intermediate valves, the grooves rusty, the cuneiform nodules light-blue on the pleural tracts, white, with a few blue spots, posteriorly. Interior greenish

white, without any strong callosity. Anterior valve with 4 slits, the 2 central ones broader; intermediate valves with 1 slit on each side, and posterior valve with 7 inequidistant slits; all teeth of the first 7 valves finely pectinated and sharp, but those of the tail-valve are stout, deeply grooved, rather blunt-edged; all insertion plates are high. Sinus flat, finely denticulate; sutural lamina angularly produced, rather thin; valve-callus not much raised.

Length, 22 mm.; breadth, 11 mm.; dry specimen. Divergence, 78°.

Animal with the gills extending nearly the whole length of the foot.

Type in my collection.

Hab.-Bay of Islands (J. C. Anderson).

Remarks. This shell is distinguished by its peculiar cuneiform sculpture from all the species of the genus known to me; it adds another genus to the New Zealand fauna.

2. Seila cochleata, n. sp. Plate XXVIII, fig. 3.

Shell small, conical, solid, dark-brown. Sculpture consisting of flat cinguli, 3 on the two whorls suceeding the embryonic shell, 4 on the following four whorls, and 5 on the body-whorl, to which are added 2 narrow spirals on the base, the upper of which arises from the suture; all are of about the same strength, the interstices of the same width as the cinguli, ornamented with fine axial striæ; the intercalation of an additional spiral takes place between the first and second rib, and it is at first very thin, but gradually attains the same strength as the others. Colour chestnut-brown. Spire elevated-conic, much higher than the aperture; outlines faintly convex. Protoconch broken off in the only specimen I have. Whorls about 10, regularly increasing, flat; base somewhat excavated. Suture deep, canaliculated by the spiral sculpture. Aperture triangularly oval, angled above, produced below into a very short and open canal. Outer lip rather thick, denticulated on the outside by the spirals, angularly rounded on meeting the straight basal lip. Columella vertical, short, arcuate, thick and rounded, subtruncate below; inner lip narrowly and thinly spread over the columella and parietal wall.

Diameter, 3-8 mm. ; height, about 10.5 mm.
Type in my collection.

Hab.-Bay of Islands (J. C. Anderson).

Remarks. In sculpture this species equals the Pliocene Bittium cinctum, Hutton (which, however, is a Seila), but the fossil species has more whorls, is higher, and the outlines of the spire are perfectly straight.

3. Aclis succincta, n. sp. Plate XXVIII, fig. 4.

Shell very small, turreted, perforate, hyaline and somewhat shining. Sculpture consisting of spiral threads, one upon the middle of the shoulder, the second (most prominent of all) on the angle of the shoulder, the third (slightly finer) a little below the periphery, and the fourth just above the suture; base with a few additional spiral lire; the whole crossed by oblique rather distant axial lines reticulating the interstices and extending over the base; the axial sculpture by far not so conspicuous as the spiral. Colour light-horny. Spire turriculate, much higher than the aperture; outlines straight. Protoconch small, obtuse, spirally sharply ridged. Whorls 6. regularly increasing, distinctly shouldered, and angularly narrowed again below the periphery; base convex. Suture distinct, margined above by the fourth spiral. Aperture subvertical, oval. Peristome discontinuous, sharp. Columella vertical, somewhat arcuate, a little broadened and subtruncate below. Perforation narrow, open. Operculum unknown.

Diameter, 1.1 mm.; height, 2-6 mm.
Type in my collection.

Hab.-Near the Snares Islands, in 50 fathoms (Captain Bollons). One specimen.

4. Pyramidella (Eulimella) limbata, n. sp. Plate XXVIII, fig. 5.

Shell small, subulate, imperforate, polished, with channelled suture. Sculpture consisting simply of straight growth-lines, slightly plicate on some of the whorls. Colour white. Spire subulate, much higher than the aperture; outlines straight. Protoconch heterostrophe, of 2 smooth whorls, the nucleus lateral. Whorls about 9, regularly increasing, flatly rounded; base convex. Suture very distinctly channelled. Aperture vertical, suboval, the sides subparallel, the base angularly effuse. Peristome solid, but not thickend, rather sharp; basal lip expanded. Columella straight, subtruncate below; inner lip not reflexed.

Diameter, 1.5 mm.; height, 5 mm.

Type in my collection.

Hab.-Bay of Islands, type; Takapuna Reef (H. S.).

5. Odostomia (s. str.) bembix, n. nov. Plate XXVIII, fig. 6. Odostomia lactea, Angas, Hutton, Cat. Mar. Moll., 1873, p. 22, &c. (not of Angas nor of Dunker). O. angasi, Tryon, Index, p. 74 (not of Tryon).

Shell small, ovato-conic, subperforate, slightly polished, subdiaphanous, fairly solid. Sculpture consisting of irregularly
