Information about Trinomen
In zoology, a trinomen, or trinominal name, refers to the name of a subspecies.
A trinomen is a name consisting of three names: generic name, specific name and subspecific name. All three names are typeset in italics, and only the generic name is capitalised. No indicator of rank is included: in zoology, subspecies is the only rank below that of species.
If the generic and specific name have already been mentioned in the same paragraph, they are often abbreviated to initial letters: for example one might write, "The Great Cormorant Phalacrocorax carbo has a distinct subspecies in Australasia, the Black Shag P. c. novaehollandiae".
In a taxonomic publication, a name is incomplete without an author citation and publication details. This indicates who published the name; in what publication; with the date of the publication.
It must be noted that while binomial nomenclature came into being and immediately gained widespread acceptance in the mid-18th century, it was not until the early 20th century that the current unified standard of trinomial nomenclature was agreed upon, mainly due to its tireless promotion by Elliott Coues. See Allen (1884) for an example of the state of the debate and competing approaches in the late 19th century. Thus, when referring especially European works of the preceding era, remember that the nomenclature used is usually not in accord with contemporary standards.

Biology
In biological nomenclature, a generic name or "the name of a genus" (sometimes "genus name") is the name of a genus. In any scientific name to consist of more than one part, the name of the genus will be the first part...... Click the link for more information.
In zoological nomenclature, a specific name or specific epithet is the second part (second name) in the name of a species (a binomen). The first part is the name of the genus.
