Urosalpinx

Urosalpinx is a genus of sea snails, marine gastropods in the subfamily Ocenebrinae of the murex snail family, Muricidae.

==Description== The shell is elongated oval, or short fusiform, longitudinally ribbed or undulated and spirally striated. The aperture has a short siphonal canal. The outer lip is dentate and lirate within. The operculum is somewhat like that of Purpura, semicordate, with the nucleus at the outer edge a little below the middle. Lingual dentition nearly like that of Trophon, the lateral teeth having an elongated base of attachment but the rhachidian tooth has numerous minute denticles between the principal ones, corresponding to ridges on the surface of the tooth, as in the Murices. Ova-capsules are oblong, shouldered, widest near the summit, compressed, carinated on either side peduncle short. The base of the attachment is very small. The aperture is median at the summit.
