Height 11, diam. 3.5 mm. Rather common, beach ,all along the: 
South Australian coast; dredged Gulf St. Vincent and Spencer

E, commensalis Tate 1898. “The Commensal Eulima.'’ 
Elongate-pyramidal, strongly curved in two directions, trans- 
lucent glassy; fawn-coloured with contained animal; smooth; 
whorls ten, moderately convex; body-whorl globosely inflated, 
thence tapering to the very acute yriHoconch; mouth semi-circular; 
outer lip much curved medially; front of mouth well rounded, 
but the margin slightly reRected, so that seen from behind there 
is the semblance of basal constriction. Height 5, diam. 2 mm. 
Generally distributed, from Bcaciiport S.A. to Itllcnsbrook W.A., 
beach and down to 100 fathoms, commensal on the long spires of 
certain sea-urchins. (Type locality — Holdfast Bay and Aldinga 
Bay, commensal with certain species of A mbiy pneustes . a genus 
ot rather long-spined sea-urchins). Mouth like that of E. temsonx 
Tryon, but protoconch very actite (not mamillatc), shell much 
narrower. 
E. inflata Tate & May 1900. ‘The inflated Eulima.” 
Whorls slightly irregularly convex; penultimate whorl somewhat 
contracted; last whorl much inflated, regularly convex; mouth 
small, roundly oval, hardly oblique; outer lip not retreating at 
the sutural margin. Height (without proloconch) 6.25, diam. 
3 mm. Rare, Beachport S.A. to Rounest Island, W.A., beach 
and down to 110 fathoms. ('Type locality — Noith coast of Tas- 
mania). Rcsembcls K. tryoni Tale & May, but thinner and long- 
er for the same number of whorls — whorls more convex; tryonx 
has a more oblique mouth, narrower base, which is oblique on 
the left side. South Australian specimens are a little longer and 
narrower than the type. 
E. mayr Tate 1900. “May*s Eulima.^’ Solid, highly pol- 
ished; white; spire with a slight apical twist from before back- 
ward, gradually tapering to an extremely allcnuated tip; whorls 
fourteen, flat; month elongate oval, a little higher than wide, 
elightly oblique; outer Hp retreating from the middle line to 
the suture. Height 7.75, diam, 2.5 mm. Gulf St. Vhneent S.A. 
to King (icorgc Sound W.A., beach and down to 35 fathoms. 
(Type locality — East coast of 'Tasmania, soutli of Swansea). 
Resembles A. intermedia, but the last whorl approximately half 
the length of shell, instead ol one third, as in that Mediterranean 
ipccics. South Australian specimens are narrower and smaller— 
the type of E. mayi appears to be unique.
