Solariella intermissa: Diagnosis: Shell without colour pattern, whitish; turbiniform, but showing considerable variation in profile and sculpture; whorls rounded, some with distinct angles, but without a tabulate shoulder; protoconch large (450-500 µm in diameter). Spiral sculpture lirate, corded at whorl angles when present; axial sculpture of prosocline pliculae which cause granulation of spiral cords. Umbilicus deep, generally narrow, but expanding rapidly and becoming funnel-shaped toward base.
Description: Shell turbiniform, spire prominent (L/D = 0,78-1,0); whorls rounded or angular, without tabulate shoulder, periphery at or near mid-whorl; teleoconch of up to 5 whorls. Sculpturally divisible into two extreme forms, the smooth typical form and the angular gilchristi form, but intermediate stages numerous. Spiral sculpture of first whorl comprising 3-7 spiral lirae; in typical form these persist, together with frequent subequal intermediaries, throughout most of shell, occasionally some whorls almost smooth; in gilchristi form up to four lirae on first whorl strengthen to form cords on later whorls, shell curvature changes at cords forming distinct angles, whorls sometimes almost flat between cords; one cord just below suture, a second (usually the strongest) 1/3 – ½ distance between suture and periphery, another one or two nearer periphery. Axial sculpture of prosocline axial pliculae, rarely starting before end of first whorl and generally strongest from second to fourth whorls; causing distinct granulation of spiral cords in gilchristi form; pliculae becoming obsolete toward periphery and on body whorl where axial sculpture present as fine irregular growth-lines only; growth-lines may interact with spiral lirae to form weak cancellation. Base generally finely Urate, but sometimes nearly smooth; axial sculpture for most part weak or obsolete in adults. Umbilicus deep but narrow, widening rapidly on to base and thus becoming funnel-shaped; sculptured by well-developed spiral lirae of unequal strength, outermost of which is usually strongest; axial pliculae strengthen or return at margin, often causing slight granulation of lirae. Aperture subcircular, peristome may or may not be complete; columella lip sometimes slightly reflected; outer lip smooth, prosocline; interior nacreous.
Protoconch: Typically solarielline, surface irregularly granular with fine spiral Urae; terminal lip slightly flared: large, 450-500 µm in diameter.
Colour: White to yellowish-white, translucent and tinged with grey when fresh, some pink/green iridescence; dark colour of animal may show through; dead shells usually lustreless; protoconch and early whorls pale to greyish-yellow when fresh, otherwise as rest of shell. Dimensions: Largest specimen, length 9,1 mm, diameter 10,1 mm.
Radula: Typically solarielline, cusps of rachidian and inner laterals rather coarsely denticulate, outer lateral large and relatively broad. Most notable feature is first marginal which has an expanded base and rather weak, slender shaft and cusp giving appearance of a nascent latero-marginal plate.

Spectamen semisculptum: Diagnosis: Shell whitish, without colour pattern; height moderate; whorls rounded, without shoulder; sculptured by close set spiral lirae, not corded; axial sculpture of subsutural and umbilical pliculae.
Description: Shell turbiniform, height moderate (L/D = 0,81-0,87); whorls evenly rounded and lacking a distinct shoulder; suture slightly sunken; periphery at mid-whorl; teleoconch of up to 3 whorls. Sculpture of spiral lirae and axial pliculae; spiral lirae begin at start of teleoconch, ca 10 on first whorl (only visible in freshest shells) becoming more numerous in later whorls as intermediaries develop; one near suture may be slightly stronger forming a weak angle; lirae similar on base and in umbilicus. Axial sculpture of close set subsutural pliculae starting near beginning of second whorl; pliculae obsolete toward periphery but reappear on base near umbilicus. Umbilicus deep, relatively narrow but expanding rapidly; margin evenly rounded or distinctly keeled; pliculate, sometimes strongly so. Aperture rounded, peristome virtually complete; outer lip prosocline, smooth; interior not obviously nacreous. Protoconch: As in S. philippense, but larger and slightly more globose, diameter 600-800 µm. Colour: Yellowish-white, translucent, dark colour of visceral mass shows through apex of live-taken specimens. Dimensions: Largest specimen, length 4,0 mm, diameter 4,6 mm.

Spectamen semisculptum: This species is most similar to S. multistriatum (Thiele, 1925) in its rounded whorl profile, spiral liration and large protoconch. That species, however, is larger and lacks axial pliculae. The present material shows some variation in the angularity and pliculation of the umbilical margin and in the presence or absence of a slightly enlarged lira near the suture.

Solariella intermissa: South-western Transkei to off Cape Point (possibly extending to Namibia—chuni), 340-1280 m (living specimens 450-1280 m, muddy deposits with sand and rubble).

Spectamen semisculptum: Distribution: Zululand to Agulhas Bank, 126-500 m (living specimens 126-420 m).
