Glyphostoma (from Ancient Greek γλύφω (glúpho), meaning "carving", and στόμα (stóma), meaning "mouth") is a genus of sea snails, marine gastropod mollusks in the family Clathurellidae.

Description The shell has a fusiform shape. The siphonal canal is rather long. The genus is characterized by a very heavy outer lip, which is strongly rugose within. The inner lip is more or less wrinkled.Julia Gardner (1947): The Molluscan Fauna of the Alum Bluff Group of Florida; Professional Paper 142, U.S. Government Printing Office, Washington, 1947
