CATALOGUE OF RECENT AND FOSSIL CONUS

  Conus vimineus Reeve, 1849.

Range: S. Red Sea, Seychelles, S. India, Sri Lanka, W. Thailand, and Philippines.

Description: Moderately small to medium-sized, light. Last whorl narrowly conoid-cylindrical to narrowly conical, outline convex adapically, almost straight below. Columella deflected dorsally. Shoulder subangulate, often indistinct, with a moderately deep exhalent notch. Spire usually of moderate height, slightly stepped; outline slightly sigmoid to slightly concave. Larval shell of 4-4.5 whorls, maximum diameter 1.1 - 1.2 mm. Suture wide and deep in larval shell and early postnuclear whorls. Teleoconch sutural ramps flat, with radial threads and 3 wide spiral grooves that may increase to 4-5 grooves in late whorls. Entire last whorl with deep, axially striate spiral grooves separating regularly spaced ribs near base and variably arranged ribs and narrow ribbons above; elevations smooth or finely granulose.

Shell Morphometry
  L 32-43 mm
  RW 0.02-0.05 g/mm
  RD 0.37-0.44
  PMD 0.81-0.88
     (Indian Ocean shells; 0.76 - 0.84 Philippine shells)
  RSH 0.15-0.25

Ground colour beige. Last whorl with spiral rows of rectangular light brown spots on ribs, fusing into flecks and axial streaks that usually cluster in 3 spiral bands, below shoulder, above centre, and near base. Colour pattern more pronounced in Indian Ocean shells (Pl. 57, Figs. 5,6,8) than in those from Philippines (Pl. 57, Fig. 7). Larval whorls grey to beige. Postnuclear sutural ramps sparsely marked with brown radial streaks. Aperture brown to brownish violet deep within.

Periostracum brownish grey, thin, translucent, smooth.

Operculum may be absent (Ramalho, pers. comm., 1989).

Habitat and Habits: Subtidal, to 50 m.

Discussion: C. vimineus is most similar to C. longurionis. For comparison, see the Discussion of that species.

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.
