CATALOGUE OF RECENT AND FOSSIL CONUS

  Conus subulatus Kiener, 1847.

Range: Philippines and Solomon Is.

Description: Moderately small to medium-sized, moderately light to moderately solid. Last whorl ventricosely conical, conoid-cylindrical or conical; outline convex adapically, less so or straight below; left side concave at base. Shoulder angulate. Spire of moderate height, outline concave. Larval shell of 2.5-2.75 whorls, maximum diameter about 0.7 mm. Teleoconch sutural ramps flat to slightly concave, with 3-4 spiral grooves in late whorls. Last whorl with spiral grooves from base to centre or beyond, separating ribs on basal third and ribbons above.

Shell Morphometry
  L 30-38 mm
  RW 0.06-0.13 g/mm
  RD 0.51-0.54
  PMD 0.75-0.86
  RSH 0.13-0.17

Ground colour grey, variably shaded with pale brown. Last whorl with an interrupted spiral band of brown bars, spots, flecks or flames below shoulder and on each side of centre, often underlain by pale brown; bands variably complete and brown markings may be widely separated or axially confluent. Apex brown. Late sutural ramps with light to dark brown radial markings. Aperture violet.

Habitat and Habits: Shallow water.

Discussion: C. subulatus has often been confused with C. collisus, C. andamanensis, and C. sertacinctus. C. collisus has a generally broader and more conical last whorl (RD 0.53-0.60; PMD 0.80-0.90), and a less angulate shoulder; its ground colour is white and its last whorl pattern includes spiral rows of dots and dashes. C. andamanensis also has a broader last whorl (RD 0.55-0.60) and a less angulate shoulder; its aperture is wider basally, the spiral sculpture of its last whorl is more uniform, and its apex white to beige but not brown. For comparison with C. sertacinctus, 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.
