Nebularia is a genus of predatory sea snails, marine gastropod mollusks in the subfamily Cylindromitrinae within the family of Mitridae.[1] This name was originally proposed as a subgenus of the genus Mitra. The type species of this genus is Mitra contracta Swainson, 1820.

Taxonomy

[edit]

In 1991, Cernohorsky considered that the subgenus Nebularia does not form a well-defined group.[2]

In 2001, Thorsson and Salisbury used the tern Nebularia as a group (and not as a valid taxonomic name), for species related to the type species Mitra coronata.[3]

Description

[edit]

The shell is impressed with transverse grooves. The body whorl is anteriorly contracted. The aperture is narrow behind, effuse in front. The margin of the outer lip is smooth.[4]

Species

[edit]

The genus Nebularia contains the following species:[1]
