The length of the shell attains 6½ mm, its diameter 3 mm; length of the aperture: 3⅓ mm, its diameter 1¼ mm. (Original description of
Mitromorpha brazieri in Latin) The shell is ovately-fusiform, spirally thinly-striated, and sculptured with growth lines. It is pale brownish and painted with indistinct transverse lines articulated with white and red. There are 5
whorls. The uppermost two whorls (the nucleus) are large, globose, smooth, shining, and horny. The remaining whorls are somewhat convex and are separated by a distinct, slightly oblique suture. The
body whorl is elongated and only slightly contracted anteriorly. The
aperture is elongated and pale brownish inside, being broadly channelled anteriorly. The outer
lip is thin. The
columella is slightly concave above, obliquely twisted below, and covered with a thin, shining callus. ==Distribution==
