The radular teeth are extremely small and very numerous. The central tooth has a bifurcated base and a single denticle. The innumerable lateral teeth are straightsided and have a simple denticle. The inner marginal teeth are about twice the width of the laterals and have four, long denticles, while the even broader outer marginals have six comblike denticles.
