36 MR. G. F. ANGAS ON NEW MARINE SHELLS. (Jan. 16, 
very finely longitudinally striated, and showing, beneath the lens, 
minute transverse strize on the upper whorls ; whorls 7, very slightly 
convex, flattened immediately below the sutures, the last large, 
inflated, and hardly subangulate at the periphery ; apical whorls of 
spire wanting ; sutures impressed ; aperture semilunar, pointed behind 
and rounded in front ; columellar margin arcuate, thickened towards 
the base ; outer lip thin, simple, rounded, a little flattened above. 
Long. 7, diam. 43 lines. 
Hab. New South Wales (coll. Brit. Mus.). 
This curious species I have provisionally placed in Mr. Arthur 
Adams’s genus Apicalia rather than among the true Stylifers. The 
family Styliferidee requires revision. 
CERITHIOPSIS PURPUREA, h. Sp. (Plate V. fig. 7.) 
Shell elongately acuminated, moderately solid, purplish brown, 
with the last rib on each whorl grey; whorls 11 or 12, encircled 
with rounded equidistant ribs, 4 to a whorl, the last smaller, an extra 
rib on the base of the last whorl, which is flattened and very minutely 
striated, the interstices finely longitudinally striated; nucleolar 
whorl sinistral; aperture quadrately ovate; outer lip thin; columella 
arcuate and produced in front. 
Length 32 lines, breadth 1 line. 
Hab. Dredged off Shark Island, Port Jackson. 
This species differs from C. crocea, Ang., in being smaller and 
more cylindrical, with a narrower base, in its style of colouring, 
and in having the lateral outline less rectilinear. A variety occurs 
of a pale livid brown colour. 
Conus (STEPHANOCONUS) SMITHI, n. sp. (Plate V. fig. 8.) 
Shell small, stoutly conoidal, irregularly, faintly, longitudinally 
striated by the lines of growth, finely transversely grooved towards 
the base, straw-colour clouded with pale chestnut ; the upper whorls 
ornamented with distant dark chestnut flames, a few scattered spots 
of the same colour, indicating two bands, occurring on the body- 
whorl, which is encircled throughout with equidistant narrow fillets 
of a pale hue closely reticulated with chestnut spots ; spire elevated ; 
whorls turreted, concave, radiately lirate ; apex papillose ; aperture 
rather wide, the outer lip angled above at its junction with the 
whorl, nearly straight, and parallel to the columella. 
Length 5, breadth 3 lines. 
Hab. Cape Solander, Botany Bay (Brazier). 
A very prettily painted little species, belonging to the same sec- 
tion as C. rutilis, Menke. 
DriLLia £MULA, n. sp. (Plate V. fig. 9.) 
Shell elongately ovately fusiform, purplish brown ; whorls 10, 
strongly carinated a little below the sutures and sharply angulated 
in the middle, below which descend irregular longitudinal ribs 
nodulous at the angle, strongly transversely ridged below the angle, 
and more finely above, the upper space between the angle and the
