Eulima coxi: Shell small, pupiform-cylindrical, glossy; translucent white, with an opaque-white band midway between the sutures, spreading downward; spire convexly tapering, slightly so for the greater part of its length, but more suddenly above, leaving the initial whorl projecting like a mucro or teat, which is tilted or oblique. Whorls five (exclusive of the apical mucro), not in the least impressed at the sutures, the suture slightly ascending and then deflexed at the aperture; base tapering. Aperture semioval, acuminate above; peristome bending forward a little below, somewhat inflexed above; columella concave, passing without angle into the parietal margin, which bears a thin callus.
Length 4, greatest diameter 1.43, length of aperture 1.4 mm.; diameter of apical " button " 0.15 mm.
Port Stephens, New South Wales, Australia, collected by Dr. J. C. Cox. Type is No. 71,306 coll. A. N. S. P.
The general contour differs considerably from that of Lambertia Montrouzieri Souv., which is moreover a far larger species. The surface is unbroken by varices, and the white line running midway of the whorls looks deceptively like the suture. Mr. Charles Hedley, the malacologist of the Australian Museum, tells me that he knows of no description of an Australian Eulima resembling this one.
