Cossmannica is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.[2]
The surface of the shell is polished, marked by faint lines of growth and microscopic spiral striations. The shell is not umbilicated. The basal fasciole is absent. The aperture is suboval. There are two columellar folds.[3]
