Narrative of a Survey of the Intertropical and Western Coasts of Australia Volume II Part 45

Sh.e.l.l orbicular conical; spire rather depressed; whorls five spirally striated; upper part flattened, expanded, white with numerous diverging red cross lines; centre flat, nearly at right angles with the upper edge, white, with a convex thread-like rib round its base, which is distantly articulated; base of the whorls convex, red, punctured and variegated with white; axis conical, concave, white, smooth at the commencement; aperture subquadrangular; inside pearly, inner lip with an obscure tooth at the end of the umbilicus; axis one-fourth, diameter one-third, of an inch.

38. Phasianella pulchra (n.s.)

Testa minuta oblique conica tenuis pellucida linea albida opaca et fasciis coccineis ornata, anfractibus valde convexis.

Sh.e.l.l minute, obliquely conical, thin, pellucid, variegated with spiral opaque white intercepted striae and several transverse scarlet bands formed of oblique lines; axis, imperforated, one-sixth, diameter one-eighth, of an inch.

This sh.e.l.l is somewhat like P. pullus, Turbo pullus of Montague, but the whorls are more convex, and it is rather differently marked.

40. Scalaria tenuis (n.s.)

Testa conica umbillcata tenuis pellucida albida unifasciata, costis albis tenuibus ereberrimis parum elevatis laevibus, anfractibus contiguis.

Sh.e.l.l conical, thin, pellucid, whitish-brown, with a narrow central spiral brown band; whorls contiguous, convex, smooth, with numerous close oblique slightly raised, thin, simple-edged cross ribs; axis umbilicated; umbilicus narrow; mouth small, ovate, orbicular; axis three-eighths, diameter one-fourth of an inch.

This sh.e.l.l is most like Scalaria princ.i.p.alis, n.o.b. Turbo princ.i.p.alis of Pallas, Chemn. 11 t. 195, f. 1876, 1877. The sh.e.l.l before me is most probably a young specimen.

This sh.e.l.l was found at low water upon the Coral Reefs, in the entrance of Prince Regent's River, on the North-west Coast.

47. Littorina australis (n.s.)

Testa ovata, conica fulva rudis spiraliter striata sulcata, spira acuta, fauce livida.

Sh.e.l.l ovate, conical, fulvous-brown, rough, with numerous impressed spiral lines; the spire acute, the whorls rather convex, last slightly angular, the columella lip purplish-brown; axis solid, with a lunate concavity behind the usual situation of the umbilicus.

48. Littorina unifasciata (n.s.)

Testa ovato-conica imperforata purpureo-albida laevigata, anfractibus convexis ultimo subangulato, apertura purpurea unifasciata.

Icon. --

Sh.e.l.l ovate conical, nearly smooth, with only a few concentric ridges, and distant, scarcely impressed, very narrow, grooves; white or purplish-white outside; the whorls rather convex, last one slightly angular in front; mouth ovate; throat purple or purplish-black with a distinct broad white spiral band just below the slight external keel; inner lip purple with a deep concavity behind it; spire acute half the length of the sh.e.l.l; axis 8/12, diameter 6/12, of an inch.

This sh.e.l.l has somewhat the shape of Littorina zigzag, the Trochus zigzag of Montague, but is all of one colour externally and has a much shorter spire.

A broken sh.e.l.l apparently of this species was brought home, but when a more perfect specimen is round, it may prove to be distinct from it.
