Comatula purpurea —A. H. Clark 1911a: 532; 1918: 271, pl. 14 fig. 16; 1931: 360, pl. 39 fig. 109, pl. 40 fig. 111, pl. 41 fig. 114.
Material examined. 3 specimens. Ambon Is. NSMT E-8143 (1 specimen, juvenile), E-8147 (2), Latuhalat, 10 m, December 1, 1992.
Description. Centrodorsal thin discoidal, 1–2.2 mm across, up to 0.6 mm thick, roundish in aboral view, with cirrus sockets in 1 aligned row. Cirri VII–VIII, 11–14, 5– 8 mm long. Longest cirrals (4 th –5 th) 1.2 times longer than wide; cirrals smooth without aboral tubercle. Radials narrowly exposed, in contact laterally. IBr 2(1+2): Ibr 1 trapezoidal, in contact laterally; Ibr 2 (axil) triangular, free laterally. IIBr not present. Arms 10; anterior arms 85 mm, posterior arms 50 mm long; first syzygy at br 1+2, second usually at br 3+4. P 1 longest, 7–8 mm long, of 30–32 segments; combs of 4–7 teeth confluent with outer edge of pinnulars. Pinnule combs to P 2.
Remarks. Comatula purpurea (Müller, 1843) was synonymized with Comatula pectinata by Rowe and Gates (1995: 148). These two species had been distinguished mainly by the arrangement of cirri (A. H. Clark 1931: 320, in key): cirri are segregated in the interradial angles in the former species, while not in the latter. The specimens (NSMT E-8143 and E-8147) show both types of cirri arrangement. We agree the synonymization by Rowe and Gates (1995).
Distribution. Singapore (Messing and Tay 2016); Indonesia, northern Australia, Philippines (A. M. Clark and Rowe 1971); Great Barrier Reef (Gibbs et al. 1976; Fabricius 1994); South China Sea (Lane et al. 2000). Depth range: 0–120 m (Lane et al. 2000).
