Gastropoda - Rostellariidae
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|K. Bandel 2007||The shell is slender fusiform with high spire and the body whorl ovoid. Its growth is terminate. On the final whorl the species specific characters are developed. The siphonal canal is an open groove that is short with the outer side longer than the inner side in Rimellinae and is a long mostly straight canal in Rostellariinae and Calyptraphorinae. The posterior end of the aperture usually continues in a narrow canal that continues onto the spire, with the only exception of Strombolaria. The apical canal may be straight or curving, short or long, with its sides spread out onto the shell in case of the Calyptraphorinae. The outer lip is thickened and may or may not have a basal sinus (stromboid notch) and may or may not bear wrinkles, ridges or spines.|
|R. L. Squires 2013||Spire high, last whorl ovoid (on last whorl, species specific characters are developed). Posterior end of aperture commonly continues in a narrow canal that ascends the spire. Outer lip can have stromboid notch (basal sinus) and can bear wrinkles, ridges, or spines. Siphonal canal open groove and straight or curving, short or long, and uncommonly with its sides spread out onto the shell (Bandel, 2007, p. 123).|
