''Hermes'' is a proposed genus of sea snails, marine gastropod mollusks in the family Conidae, the cone snails and their allies. This genus currently (November 2011) is still treated by some experts as an "alternative representation" of this group of species. When the "alternative representations" are not used, this group of species is instead still placed in the Linnaean genus ''Conus''. ==Distinguishing characteristics== The Tucker & Tenorio 2009 taxonomy distinguishes ''Hermes'' from ''Conus'' in the following ways:〔Tucker J.K. & Tenorio M.J. (2009), Systematic Classification of Recent and Fossil Conoidean Gastropods, ConchBooks, Hankenheim, Germany, 295 pp.〕 * Genus ''Conus'' ''sensu stricto'' Linnaeus, 1758 :: Shell characters (living and fossil species) :::The basic shell shape is conical to elongated conical, has a deep anal notch on the shoulder, a smooth periostracum and a small operculum. The shoulder of the shell is usually nodulose and the protoconch is usually multispiral. Markings often include the presence of tents except for black or white color variants, with the absence of spiral lines of minute tents and textile bars. ::Radular tooth (not known for fossil species) :::The radula has an elongated anterior section with serrations and a large exposed terminating cusp, a non-obvious waist, blade is either small or absent and has a short barb, and lacks a basal spur. ::Geographical distribution :::These species are found in the Indo-Pacific region. ::Feeding habits :::These species eat other gastropods including cones.〔 * Genus ''Hermes'' Montfort, 1810 ::Shell characters (living and fossil species) :::The shell is elongated and subcylindrical in shape with a tubular body whorl. The protoconch is multispiral. The anal notch is shallow. The shoulders are rounded to subangular. The shell is ornamented with nodules which die out in the early spire whorls, two or more cords on the whorl tops, and well developed ridges on the body whorl. The periostracum is smooth, and the operculum is small. ::Radular tooth (not known for fossil species) :::The anterior section of the radular tooth is shorter than the length of the posterior section, and the blade is long and may cover the full length of the anterior section. A basal spur is present, the barb is short. The radular tooth has serrations, and a terminating cusp. ::Geographical distribution :::The species in this genus occur in the Indo-Pacific region, including Australia. ::Feeding habits :::The radular tooth suggests that these cone snails are vermivorous, meaning that the cones prey on polychaete worms, however ''Hermes nussatellus'' has been reported to feed on mollusks.〔〔A.R.
