Updated: May 19, 2025

This beautiful snail is of a brightly shining yellowish or greenish horn colour. The whorls of its spire are small, but the body whorl, whilst preserving a wide diameter throughout, gradually increases in trumpet-like manner to the round mouth. It belongs to the same group with H. olivetorum and H. nitida, and is allied to the Australian H. ptycomphala.
