Family Trichasteridae

Astroceras Lyman, 1879

Astroceras elegans (Bell)

• Mortensen, Th. 1924. Vid. Medd. dansk naturh. For., 77, p. 107. Pl. VI (3).

Material Examined: One specimen, 60–100 fathoms, N.P. Station 9, Bay of Plenty.

The species is also known from Discovery Station 934, 92–98 metres, north of New Zealand (Mortensen, 1936, p. 241), from east of North Cape, 70 fathoms (Bell, 1917), and off Three Kings, Capt. Bollons, 60 fathoms, Mortensen (1924, p. 108).

Although all of these records are from the outer part of the shelf, it is highly probable that the principal home of the species is on the deeper slope, beyond 100 fathoms.
