Heliastes roseus Günther, 1880:45 , plate XX, fig. D (original description, illustration; lectotype, herein designated, BMNH 1879.5 .14.10, 64.6 mm SL; type locality off the Kai Islands , Indonesia, Challenger station 192). Zabulon roseus: Whitley, 1928:297 (new combination).

Description. Dorsal-fin rays XI, 9. Anal-fin rays III, 9. Pectoral-fin rays 19. Pseudobranch with 11 or 12 filaments. Gillrakers 7 to 9 + 17 to 19, total 24 to 28. Tubed lateral-line scales 14 to 17. Midbody lateral scales 24 to 27. Circum caudal-peduncular scales 15 or 16. Scales between anal-fin origin and lateral line 8 or 9. Caudal fin subtruncated ( Günther, 1880:45, plate XX, fig D). Selected morphometric data are presented in Table 2 .

Coloration. “Uniform rose coloured” ( Günther, 1880:45).

Designation of lectotype. When Günther (1880:45) described Heliastes roseus he did not designate a holotype. There are five syntypes of this species in the Natural History Museum, London: BMNH 1879.5.14:10–11 (two specimens, 53.0 & 64.6 mm SL) and BMNH 1890.2.26:141–3 (three specimens, 49.2–58.9 mm SL). To unequivocally fix the name of this species to a zoological entity, we hereby designate as the lectotype of Heliastes roseus the syntype of 64.6 mm SL (BMNH 1879.5.14.10). By that action the other syntypes—BMNH 1879.5.14.11 (53.0 mm SL) and BMNH 1890.2.26.141–3 (3: 49.2–58. 9 mm SL) become paralectotypes.

Distribution. Known only from the type specimens collected off the Kai Islands, Indonesia, at Challenger station 192 (5°49’15” S, 132°14’15” E, in 129 fathoms –236 meters).

Comment. Along with the type specimens of Grammatonotus roseus , the lectotype and paralectotype of Propoma roseum (= Symphysanodon typus, family Symphysanodontidae ) were also collected at Challenger station 192 ( Anderson, 1970:333).

Material examined. Five specimens, 49.2 to 64.6 mm SL. INDONESIA, off the Kai Islands: BMNH 1879.5 .14.10 (lectotype: 64.6 mm SL), BMNH 1879.5.14.11 (paralectotype: 53.0 mm SL), BMNH 1890.2.26.141–3 (3 paralectotypes: 49.2–58.9 mm SL).
