Shell acicular, smooth, glossy, transparent or opaque, without varices. Colour : the opaque or semitransparent shells are milk-white, with a dull opaque band above the sutures, next above which is an indistinct, often interrupted orange line; another orange line runs round the periphery of the last whorl and tinges the outer lip. Whorls twelve, with straight sides, parted by a linear suture. Base attenuated. Aperture rather oblique, narrowly pyriform, effuse anteriorly, posteriorly subchannelled, a thin callus on the body whorl, columella slightly curved, thickened within. Length, 7,7 mm. Breadth, 1,2 mm.
A few specimens from 41-50 fathoms off Cape Three Points. A small series taken by Mr. A. U. Henn in 10£ fathoms off Bow Reef, near Cape Sidmouth, North Queensland, possesses a third orange line around the base, but otherwise so closely agree that I regard them as belonging to this species.
Described as Leiostraca lodderae

This species has a general resemblance to L. bivittata, H. & A. Ad., but as that is described as having from nine to ten whorls in a length of 14 mm., I consider it distinct. Mr. W. F. Petterd has kindly identified my specimen as his Eulima vitrea, of which the description suits a half grown L. lodderae. The decision of Tate & May that E. vitrea, Petterd, is Leiostraca bivittata seems to me not in accord with the proportions noted for each. Other allied species are Leiostraca samoensis, Crosse, longer, and in proportion much broader, and Eulima acerrima, Watson, which has the same number of whorls as L. subtilis in half the total length.
