Taxonomy and scientific names
The naming of species with a two-part Latin name, such as Tenualosa ilisha for the hilsa, followed by who named it and when.
Also: binomial name, authority
Every described species has a scientific name in two parts: the genus, written with a capital, and the species, in lower case, as in Labeo rohita for the rohu. The name is followed by the authority, the person who first described the species and the year, such as Hamilton, 1822. Brackets around the authority mean the species has since moved to a different genus. Common names change from place to place, so the hilsa is ilish in Bengali, palla in Sindhi and Punjabi, and pulasa in Andhra, but the scientific name is the same worldwide.
