Genus names whose last component is a Latin noun (or Latin adjective treated like a noun) obtain their gender from the gender of that noun [Rule 65 (1), Rule 65 (2)]. A list of genus names formed in that manner and being in the neuter gender is provided below. Names with Latin components in other positions are not listed here. See also the LPSN introductory page on forming names.
