Length 2 in., breadth 7\ lin. Hab. Lake Macquarie ; and Cape Solander, Botany Bay, New South Wales. Named after its discoverer, Mr. John Brazier, an enthusiastic and intelligent conchologist, who has contributed much to our knowledge of the Australian mollusca. HELIX (TROCHOMORPHA) DEIOPEIA, n. s. (Plate II. fig. 4.) Shell deeply umbilicated, depressedly and convexly conical, moderately thin, finely obliquely irregularly striated, upper whorls brown, last whorl black, ornamented with numerous pale diaphanous oblique stripe-like spots ; spire convexly depressedly conical, apex obtuse, suture narrowly margined ; whorls six, rather convex, the last not descending, keeled, somewhat flattened at the base ; umbilicus conical, moderate, partly surrounded by a faint horn-coloured band passing into the interior of the shell; aperture oblique, truncately oval; peristome non-continuous,pale horn-colour,margins converging, the right thin, slightly expanded, the basal a little thickened, sinuous, and somewhat reflexed.
