Mitromorpha


Miltromorpha is a genus of sea snails, marine gastropod mollusks in the family Mitromorphidae, in the superfamily Conoidea the cone snails and their allies. This genus was originally described by Carpenter off the west coast of the United States. The species occur mainly on the continental shelf and in insular environments. Their real diversity is poorly understood.
Mitromorpha was previously categorized under the family Conidae, subfamily Clathurellinae..
The genus Mitrolumna is currently treated as a synonym or subgenus of Mitromorpha, but is available for the Eastern Atlantic and Mediterranean species, if these are considered to form a distinct radiation. The same genus is also used for a number of extinct species:
The small shells have an elongate fusiform shape. They are generally strongly spirally sculptured. The flattened shells are crossed by longitudinal plicae and revolving lirae. The aperture is long and narrowly oval. The anal sinus is in most cases obsolete. The outer lip is acute, smooth within, occasionally scarcely sinuated posteriorly. The columella is straight, bearing a number of short plicae or teeth upon it in the middle and slightly transversely lirate.
