Hastula brazieri (Angas, 1871)

Description: Shell of about 14 adult whorls; early whorls straight sided, later whorls or body whorl weakly concave, subsutural groove absent. Axial sculpture of curved axial ribs, low and wide, varying in spacing and width, almost absent on some shells, and sometimes weakly nodulose at top. Spiral sculpture of irregular, microscopic threads and grooves. Fasciolar band well defined with sharp edge; siphonal notch moderately deep. Outer lip thin and simple. Coloured with tan streaks between white axial ribs, sometimes with tan colouration restricted to the upper third of whorls; base of body whorl tan.

Size: Up to 40 mm in length

Distribution: Endemic to Australia; Yamba, NSW, to SA, including Tasmania.

Habitat: Subtidal, to 40 m., but most specimens are taken as beach shells. Uncommon.

Comparison: This is a tall, slender shell, generally with weak sculpture, which allied with the absence of a subsutural groove, distinguishes it from the other NSW terebrids. The colour pattern of brown streaks between the axial ribs is another characteristic feature.
