Semelangulus
brazieri
(G.B. Sowerby II, 1869) Description:
Original description by G.B. Sowerby II, 1869: “Shell small,
oblong, compressed, thin, smooth, pink, subpellucid; posterior side
short, truncated, angular, behind the angle flattened, concentrically
ridged; cardinal teeth small; lateral none”. Size:
Size not given in original description, and still uncertain. Distribution:
Type locality “Port Jackson” NSW. Habitat:
Not given in original description, and still uncertain. Remarks:
This species is difficult to recognise from the original
description and has been so since it’s description in 1869. There are
only three lots identified as this in the Australian Museum collection,
reflecting the difficulty in identifying the species. The illustration
accompanying the original description was small (shown here as Fig. 1)
and could match several NSW species. Hedley
(1913) dismissed a suggestion that the type specimens were Tellina
ticaonica Deshayes, 1855. No
further understanding of the species was presented until Lamprell &
Whitehead (1992, sp. 311) gave a description and figure of their
interpretation of species. However, their description has taken
liberties with the known data, giving a length of 20 mm and a
distribution of “New South Wales” (implying all of NSW) without
basis. But the specimen they illustrated in their fig. 311 (Australian
Museum C. 15914) matches the original description reasonably well and is
accepted here as illustrative of the species. This specimen is figured
here in Fig. 2. Fig.
