Motourrcotir Triphora innotabilis, Hedley. 3 BA 
Triphora innotahilis, Hedley, Proc. Linn. Soc., New outh 
Wales, 1903 (1902), part 4, p. 608, pl. xxxii., figs. 28, 24, 25. 
Type locality—Sydney Harbour. 
Dredged in Gulf St. Vincent, (?) depth, 10 good, 4 mod- 
erate; in 22 fathoms, Investigator Strait, 2 perfect and 
fresh ; in 62 fathoms off Cape Borda, 1 perfect. Taken in 
shell sand, Edithburgh and at Streaky Bay, good. Identi- 
fied by Mv. Hedley from his type. 
JNhtosit ery iphora latilirata, n. sp. Pl. xxvi., fig. 1. 36 Y- 
Shell sinistral, solid, elongate-conic. Protoconch of 5 
whorls, smooth and round. Spire-whorls 13, flat, sloping ; 
suture rather wider than the spaces between the spiral ribs. 
Spirals 3, flat, wide, nearly smooth on the surface: inter- 
stices narrow, punctated by close-set axial incisions, which 
also cut the sides of the lire. Body-whorl rhomboidal, with 
three spiral ribs, towards the aperture the interspaces are 
occupied each by a short, rapidly-widening spiral; the axial 
incisions are more distinct towards the aperture. Base con- 
vex with a peripheral spiral, rounded, smooth keel, and a 
second more anterior, punctated between. Aperture roundly 
quadrate:; outer lip sloping, straight, ascending at the suture 
and pinched into a tiny sinus, anteriorly circular and effuse ; 
in profile straight, minutely retrocurrent at the suture, ob- 
liquely very slightly antecurrent anteriorly. Canal well 
marked, nearly closed, especially at the junction with the 
aperture, markedly recurved. Inner lip distinct, slightly 
erect. Colour, white. 
Dim.—Uength, 10°5 mm.; breadth, 2°5 mm. 
Locality.—Type, Gulf St. Vincent, (2) depth, with 23 
others moderate: in 15 to 20 fathoms off St. Francis Island, 
1 moderate: in 24 fathoms off Newland Head, 1 moderate ;. 
in 55 fathoms off Cape Borda, 1 good. 
Variations.—In the shell from 55 fathoms, in the ante- 
penultimate whorl an interstitial thread arises between the 
middle and anterior spirals, and becomes a definite though 
small lira, In some large shells a thin sutural lamina is 
seen between the later whorls. A large broken specimen 
would measure 15 mm. if complete. In one individual the 
posterior spiral lira throughout the shell is tinged brown. 
Welestritteriptore: armillata, n, sp. Pl. xxii., fig. 5. 34S ores 1909 
Shell solid, elongate-conic. Protoconch of 4 whorls, con- 
vex, centrally carinate, the fourth with two approximate 
carinz; crowded fine axial bars, concave forward above the 
,
