The term "Tritonia gilberti" is not a widely recognized or established name in mainstream biological taxonomy or common encyclopedic sources. It does not appear in authoritative databases such as the World Register of Marine Species (WoRMS) or the Integrated Taxonomic Information System (ITIS) as a valid species under the genus Tritonia (a group of marine sea slugs, nudibranchs).
Given the structure, "Tritonia" is a valid genus name for nudibranch mollusks, and "gilberti" would conventionally be a specific epithet, possibly honoring someone named Gilbert. However, no verifiable published description or reliable record for a species with this binomial could be confirmed. It may represent an unpublished name, a misspelling, a nomen nudum (a name without a formal description), or a usage in a non-scientific context. Without access to a credible source or original description, no further factual information can be provided.
