Borsonia
''Borsonia'' is a genus of sea snails, marine gastropod mollusks in the family Borsoniidae. Description The fusiform shell has medium to small size. It has an elevated spire and a well-marked siphonal canal. The whorls of the spire are usually angulated near the middle. On this angle they show elongated nodes or axial ribs. These nodes disappear almost completely at the last section of the body whorl. The sutures are distinct. The aperture is elongate and is about half as long as the shell. The simple outer lip curves back near the top and forms a deep notch. The columella is nearly straight and has none, one or two strong plications on the upper half. The anal sinus of the outer lip is not deep The sinus area between and the strong sutural cord are well excavated. There is an opening in the infrasutural depression of the body whorl. Distribution At considerable depths in the subtropical and temperate waters of the Pacific Ocean and the Atlantic Ocean; in shallower boreal w ...

(Original description) The rather thick shell has a fusiform shape and is yellowish-white. The upper whorls are lost by erosion. Of the remaining 6 whorls the upper ones are still eroded, of the 4 whorls which are in sufficient state of preservation, the upper 2 are slightly angular, their upper part a little excavated, the lower part more convex, with a single row of nodules on the limit. In the lower ones the shell is slightly excavated below the suture, but otherwise regularly rounded, without nodules.

Borsonia Hirondelleae
''Borsonia hirondelleae'' is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae. The specific name ''hirondelleae'' refers to the ship ''Hirondelle'', that was used to collect molluscs from the Bay of Biscay. Dautzenberg, P.
