CATALOGUE OF RECENT AND FOSSIL CONUS

  Conus lentiginosus Reeve, 1844.

Range: Western coast of India.

Description: Moderately small to medium-sized, moderately light to moderately solid. Last whorl conical, ventricosely conical or slightly pyriform; outline convex at adapical two-thirds to three-fourths, straight or concave below; left side consistently sigmoid, right side sometimes almost straight. Shoulder angulate. Spire of moderate height, outline concave or sigmoid. Larval shell of about 2 whorls, maximum diameter 0.9-1.0 mm. First 3-5 postnuclear whorls tuberculate. Teleoconch sutural ramps flat to slightly concave, with 1 increasing to 1-3 spiral grooves, obsolete or replaced by many spiral striae in late whorls. Last whorl with axially striate spiral grooves on basal third, separated by ribs anteriorly and by ribbons posteriorly.

Shell Morphometry
  L 29-38 mm
  RW 0.08-0.16 g/mm
  RD 0.60-0.69
  PMD 0.80-0.89
  RSH 0.18-0.24

Ground colour white, variably tinged with violet. Last whorl with confluent brown axial flames, generally arranged in 3 spiral bands, below shoulder, near centre and within basal third. Spiral rows of brown dots and dashes extend from base to shoulder, varying in number and arrangement. Larval whorls white. Teleoconch sutural ramps with brown radial blotches. Aperture white, tinged with violet deep within.

Periostracum yellowish brown, thin, translucent, smooth.

Habitat and Habits: Inshore, shallow subtidal (Kohn, 1978).

Discussion: C. lentiginosus is similar to C. dictator, C. milesi, C. traversianus, C. stocki and C. eximius. For comparison with the first 4 congeners, see the DISCUSSIONS of those species. C. eximius attains larger size, often has a lower spire (RSH 0.08- 0.26), and is separable by its pale brown multispiral larval shell (3.5 whorls), smooth early postnuclear whorls, prominent spiral grooves on later sutural ramps, and white aperture.

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.
