S.B. _Militaris_, WILBUR. _Carnifex_, JABLONSK. _Profanus_, DESFONT by James Russell Lowell

Lowell is mimicking a naturalist as he writes a formal species description, similar to those in 18th- and 19th-century entomology texts. At that time, Latin served as the international language of science, so its use makes the satire resemble an authentic field report. This choice also provides Lowell with some protection—by using the detached tone of scientific Latin, he can express harsh opinions while maintaining the guise of objectivity.

The 'specimen' is a satirical portrayal of pro-slavery politicians and slaveholders from the South. The setting ('civitat. Americ. austral.' — cities of the American South), the affinity for blood and slaughterhouses, the insatiable demand for public resources, and the practice of enslaving S. Guineensis all directly reference the antebellum Southern political elite.

In Latin, candidatus translates to 'clothed in white' — Roman candidates donned white togas to represent purity. Lowell plays on this by using it as the creature's 'popular name,' which serves as a punchline: this blood-soaked, brainless parasite is referred to as 'the Candidate,' highlighting the stark contrast between a politician's polished public persona and what Lowell perceives as the grim reality.

Outis means 'Nobody' in Greek — it's the name Odysseus uses for the Cyclops in Homer's Odyssey. So, 'Isaac Nobody' is a fictional scholar created by Lowell. The footnote pokes fun at academic citation disputes, with the humor lying in the debate among these made-up authorities about whether this politician-insect resembles a common soldier-bug or more closely resembles Beelzebub.

Guinea was the name commonly used by Europeans to refer to the West African coast from which millions of enslaved individuals were taken. Lowell labels enslaved Africans with a fictional species name within the same taxonomic framework, reflecting the pseudo-scientific racism that justified slavery. He then quickly shifts the focus back to the enslaver as the real subject of study.

The narrator mentions that he carefully dissected the creature's head but found no trace of a brain, which is something nearly all insects possess. This serves as Lowell's most pointed insult: the pro-slavery politician is not only morally bankrupt but also, in a literal sense, less intelligent than an ordinary bug. By framing it scientifically, the insult comes across as a fact rather than just a personal opinion.

It’s a prose poem or a satirical sketch presented as a naturalist's field entry. Lowell opts for prose instead of verse; the 'poetic' feel arises from the rich irony and precise language rather than from any meter or rhyme. This piece fits within a tradition of satirical mock-documents, alongside works by Swift and later Bierce.

These are the three 'species' or varieties mentioned. Militaris translates to 'of the soldier' or 'military.' Carnifex translates to 'butcher' or 'executioner.' Profanus translates to 'profane' or 'unholy.' Together, they represent three aspects of the same archetype: the aggressive militarist, the killer, and the godless. The authors following each name (Wilbur, Jablonsk, Desfont) are fictional naturalists, adding to the parody of a genuine taxonomic entry.
