Range: Aden and N. Somalia.

Description: Medium-sized to moderately large, solid. Last whorl conical, outline almost straight. Shoulder angulate. Spire of low to moderate height, may be stepped in later whorls; outline concave to almost straight. Teleoconch sutural ramps flat to concave, occasionally with 3-5 weak spiral grooves in late whorls. Last whorl with a few obsolete spiral ribs at base.

Shell Morphometry
  L 55-97 mm

  PMD 0.86-0.94
  RSH 0.09-0.15

Ground colour white. Last whorl with a variably broad light to dark brown spiral band on each side of centre and axial streaks or flames; a third often interrupted colour band may occur below shoulder. Coarse or fine darker spiral lines extend from base to shoulder, but vary in number and arrangement. Shells that have only axial flames intergrade with shells that have last whorl largely brown and only with spiral pattern elements. Somalian specimens (form anadema; Pl. 34, Figs. 19, 20) characterized by a yellowish brown to orange, predominantly spirally arranged pattern. Base yellowish brown to brown. Larval whorls beige to brown. Postnuclear sutural ramps with brown radial streaks and blotches that extend over outer margins. Aperture white.

Periostracum beige, thin, translucent, and smooth.

Radular teeth long and narrow, with a weak adapical barb opposite an obsolete blade; a long serration of spiny denticles extends down the shaft to about 1/4 the length above base.

Habitat and Habits: In 10-25 m, on mud, coral rubble and in sand channels among coral reefs.

Discussion: C. fumigatus may be similar to C. splendidulus but has a generally broader last whorl (RD 0.57- 0.79), its aperture is violet in larger specimens, and its subshoulder area lacks a colour band as may occur in C. splendidulus. For comparison with C. amadis, see the Discussion of that species. C. splendidulus was also referred to as C. argillaceus Perry, 1811 (Walls, [1979]), but this is a nomen dubium (Röckel, 1979; Coomans et. al., 1981; Kohn, 1986). C. anadema, known only from Kiener's illustration, was synonymized with C. monile by Walls ([1979]) and considered a valid species by Coomans et al. (1980) and Richard (1990). Kiener's figure (Pl. 70, Fig. 7) represents the population of C. splendidulus from Somalia.

This section contains verbatim reproductions of the accounts of 316 species of Conus from the Indo-Pacific region, from Manual of the Living Conidae, by Röckel, Korn and Kohn (1995). They are reproduced with the kind permission of the present publisher, Conchbooks.

All plates and figures referred to in the text are also in Röckel, Korn & Kohn, 1995. Manual of the Living Conidae Vol. 1: Indo-Pacific Region.

The range maps have been modified so that each species account has it own map, rather than one map that showed the ranges of several species in the original work. This was necessary because each species account is on a separate page on the website and not confined to the order of accounts in the book.
