International code of nomenclature :
In 1898, international congress established a commission to frame international code of Botanical and Zoological nomenclature. This commission suggested some rules in 1901 which were modified in 1964.
- The zoological name (scientific name) should be Latinized
- Every animal is to be given a zoological name according to binomial system/trinomial system.
- The first letter of genus name should always be capital.
- The first letter of species name should always be small.
- The scientific name should be printed in Italics or underlined separately.
- The name of subspecies, if any, always comes after the species name.
- If many scientific names have been given to the same animal by different authors, the name used prior to those included by Linnaeus in “Systema Naturae,” 10th edition (1758) is considered valid.
- The name of discoverer if any, appears at the end of the scientific name.
- The two genera should not have same name & similarity two species in a genus. However, species name may figure many times but each time with a separate genus. For example Elephas indicus (Indian elephant) & Bos indicus (cow).
- Suffix idae should be added in the name of genus to create family and suffix inae should be added in the name of genus to create sub-family
