Specimens of this species possess a large white peripheral flange composed of a mass of calcareous spicules similar to that illustrated in the original description of Carterina spiculotesta (Carter, 1877). Tests are trochospiral throughout with chambers increasing rapidly in size. The last whorl comprises only 2-3 chambers. The deep umbilicus may be filled up with a spicular mass that may extend into the peripheral flange. Only the first (about 10) chambers are brownish in color, the other ones are yellowish or white. The spicules are elongated, fusiform, arranged somewhat parallel to the periphery on the spiral side and radial on the umbilical side.
