Description
Siniotrochus myriodontus Gage & Billett, 1986
(Figs 13 A, 14)
Siniotrochus myriodontus Gage & Billett, 1986: 266 –272, figs 28(C–E), 29–31; Bohn, 2005: 232 –234, figs 1(A–B), 2
Material. M 48/1347: 1 posterior fragment (ZSM 20020016). M 48/1351: 2 posterior fragments (ZSM 20020015).
Remarks. Gage and Billett (1986) provide an excellent description of this species, including detailed information on a variety of taxonomically important wheel parameters. Given that the current specimens have already been treated in more detail (Bohn 2005) the species is only shortly outlined: body about cylindrical, up to 31 mm long and 7 mm wide; tentacles 12, with four pairs of lateral digits; calcareous ring with 5 radial and 5 interradial plates; body wall with single layer of wheel deposits of the socalled siniotrochid type (Fig. 13 A); wheel diameter 414 (284–560); hub about half the diameter of the wheel, perforated by several holes; spokes 17 (12–25); inwardpointing teeth 42 (30–67); outwardpointing primary teeth 18 (11–31); outwardpointing secondary teeth 6 (0–29) (arrowheads in Fig. 13 A); simple rod deposits present in tentacles and around anus.
Siniotrochus myriodontus closely resembles the northwestern Atlantic Ocean S. phoxus Pawson, 1971 from which it differs by the presence of outwardpointing secondary teeth on the wheels.
Distribution. (Fig. 14) Northeastern Atlantic Ocean (Porcupine Seabight) and southeastern Atlantic Ocean, 3490–5389 m (Bohn 2005; Gage & Billett 1986).
