32 . Snut h ul ustralicn: Shells. 
in life; axially faintly striate; protoconch subtumid; adult whorls 
six, conspicuously tricarinate, -flat, carinae raised, rounded; base 
subconvex, lirate; mouth pyriform, entire; inner lio reflexed, with 
a very distinct transverse tooth-like fold. Height 2.5, diain. 1 
mm. Streaky Bay. (Type locality — Long Bay, Tasmania, 
dredged). A minute three-keeled shell, upper and lower keels 
so closely united as to appear one broad keel in which the suture 
is concealed. 
STROMBIFORMIDAE. 
Small, genrally elongated, tapering or turriculate, shining, 
polished, spire sometimes curved; mouth oval or pyriform, entire, 
lip simple, columellar margin more or less thickened; operculum 
horny, paucispiral, sometimes absent. Distribution — Tropical and 
Temperate. Fossil — Jurassic. Animal with slender tapering 
tentacles and eyes sessile at their outer bases; proboscis retractile, 
invaginate, when extended very lang; mouth without jaw or rad- 
ula; foot elongated, produced in front; mantle with anterior rudi- 
mentary siphonal fold. They creep with the foot much in advance 
of the head, which is usually concealed within the mouth of the 
shell, the tentacles only protuding. More or less parasitic on 
sea-urchins, holothurians. Sexes probably distinct. 
Eulima Risso 1826. Jeffreys refers to the name Eultma as a 
compound of a Greek and a Latin word, signifying finely polished; 
VVoodward gives it as from enlhma, ravenous hunger. Awl-shaped, 
polished, shining like porcelain; not umbilicate; spire finely taper- 
ing to a regular point and slightly twisted to one side; whorls 
many; suture slight; varices slight externally, but forming small 
ribs within, marking the position of successive months; mouth 
ovate, entire, angulate above and rounded below; columellar 
border reflected; operculum horny, paucispiral, nucleus near the 
inner lip. Type — £. polita Linne (British Isles) — Eulima 
Aegantissima Montag, 
E. augur Angas 1865 (— E. proxima Sowerby: — E. aph- 
eles Tenison-Woods 1878: E, margmata Tenison-Woods 1878). 
‘'The Augur Eulima.” Rather narrow, solid; wliite, opaque; 
smooth; spire very slightly curved; the old mouths not uniformly 
along one side, there may be a variation of a quarter of a whorl 
either way; protoconch blunt, of two scarcely convex whorls, 
slightly oblique; the protoconch is usually missing and dredged 
examples show the irregular fracture where it has broken away; 
shore specimens have the posterior end blunt from beach rolling; 
adult whorls eight, early whorls more or less convex, later whorls 
rather flattened; periphery of body-whorl rounded; suture mar- 
gined; mouth suboval; outer lip sinuous above; columella straight.
