Calliostoma javanicum: Leal, 1991: 45; Hess & Abbott, 1994: 142; Lyons, 1998: 16; Espinosa et al., 2007: 64, fig. 003; Williams et al., 2008: 487, tab. 2; Rosenberg et al., 2009: 622; Williams et al., 2010: 785, tab. 1.

Calliostoma sp.1: Leal, 1991: 47.

Type material. Holotype: MHNG-MOLL-51496.

Type locality. Java (in error; see Leal 1991) .

Previously known distribution. East Florida to Brazil, live specimens from 1–97 m (Leal, 1991; Rosenberg et al. 2009).

New occurrences. Off southeastern Brazil, Martim Vaz Island and Abrolhos Bank, 780–940 m (shells only).

Habitat. Benthic, on coral, rocky and sandy habitats (Rodríguez-Sevilla et al. 2009).

Material examined. Brazil: Espírito Santo: off São Mateus, Abrolhos Slope, 19°40’S, 37°48’W, MD55 sta. CB77, 790– 940 m, MNHN, 1 sh (27/v/1987); off Vitória, Martim Vaz Island, 20°32’S, 28°52’W, MD55 sta. DC55, 780– 795 m, MNHN, 1 sh (20/v/1987). Additional non-MD55 material: holotype .

Measurements. ~6 whorls, H= 5.4 mm, D= 5.5 mm (juvenile).

Remarks. According to Rosenberg et al. (2009), the bathymetric range of this species is 1– 97 m. The wellpreserved juvenile specimen found in the present samples at 780–795 m depth suggests a greater maximum depth, though this single shell could still have been carried away from its original area. Leal (1991) reported C. javanicum from Vitoria Bank (MD55 stations DC22, DC26), Montague Bank (sta. DC27), Jasseur Bank (sta. DC34, DC35), Davis Bank (sta. DC40), Dogaressa Bank (sta. DC42) and Columbia Bank (sta. DC47). The species is newly reported here from Trindade (off Martim Vaz Island) further eastward, and the Abrolhos Bank to the west.
