The generic name Bathykorus references the habitat and shape of the species. Bathy (Greek; from bathus, depth or deep) refers to the deep-sea habitat of the species, and korus (Greek; helmet) refers to the helmet-like shape of the bell. The specific epithet of bouilloni is named in honor of the late Dr. Jean Bouillon, (1926–2009). Dr. Bouillon’s studies spanned over 60 years, and described 17 families, 34 genera, and 114 species. His work and his generous sprit continue to enlighten and inspire generations of biologists. Diagnosis. Generic Diagnosis
