A co-type shows a brown tinting of the two carinae and of that part of the axial ribs connecting them, most marked at the tubercles of junction. It contains seven whorls . The protoconch contains two , homostrophe, convex whorls with 20 fine spiral incisions ending abruptly in a varix. The spire whorls show angulation at one-fourth the distance from the lower suture. They are uniformly concave between the angulations. Their sculpture shows axial ribs, valid, rounded nearly as wide as the interspaces, and spiral lirae, wider anteriorly, wider than their interspaces, crossing the ribs. There are six above the angulation, and two below it. Fine accremental striae can be seen under the lens. The suture is distinct, linear, undulating, conv ...

Exomilus Lutarius
''Exomilus lutarius'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. Description The length of the shell attains 3 mm, its diameter 1.15 mm. (Original description) The small, solid shell is cylindrical and abruptly truncate above. It contains five whorls, three forming the protoconch, sloping on the shoulder, perpendicular at the side, and concave at the base. The colour of the shell is grey (? bleached). The sculpture consists of deep narrow pits are formed by the intersection of radial and spiral sculpture. The radials are strong, prominent and perpendicular. The ribs are continuous, about a dozen to a whorl, knotted at the crossing of the spirals, which number four on the upper and twelve on the lower whorl. The spiral defines the basal angle larger and more prominent.

Raphitomidae
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Raphitominae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. The family was found to be monophyletic. Description The Raphitomidae is the largest, most diverse and most variable taxon in the Conoidea, with the greatest number of species and the largest ecological range (from the tropics to the pole) and largest vertical range (intertidal to hadal depths). The shells of species in the Raphitomidae are very variable in shape (buccinoid to ovate, elongate-fusiform, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
