Spiral sculpture of subsutural ramp of last whorl with adis, IP and abis followed by P1, s1, P2, s2, P3, s3, P4, s4, P5, P6, s6 and few tertiary cords on convex part of whorl. Primary cords increasing in height and strength abapically. Aperture broadly ovate. Columellar lip smooth. Outer lip erect, denticulate, with low, elongate denticles within. Siphonal canal moderately long, broad, narrowly open, with 3 moderately long, abapically bent ADP, MP, and ABP spines. ADP strongly dorsally bent.

This species was originally misidentified as Chicomurex laciniatus (Sowerby) by Japanese authors; Radwin & D'Attilio (1976: pl. 6, fig. 1) identified a specimen of C. elliscrossi as C. superbus, but C. elliscrossi has a broader shell with stronger intervarical nodes, a broader aperture, more shouldered and thicker shell, narrower and straighter columellar lip, smaller anal notch, a lower spire and a broader siphonal canal.

Type locality. Kii Peninsula, Japan.
Distribution. Indo-W.Pac (P). New Caledonia, Vietnam (Thach, 2005), and south-eastern Japan.
