Viriola intergranosa (Hervier, 1898)
Viriola intergranosa is a gastropod mollusk in the family Triphoridae, a family of very small sea snails. Almost all species in this family are micromollusks and almost all have left-handed shell coiling. Members of the family are found worldwide, but the majority are found in the Indo-Pacific. Most species live between the intertidal zone and offshore at a depth of between 200 m and 500 m (rarely up to 1,000 m).
The shells of the Triphoridae are small (between 2 mm and 10 mm, rarely 50 mm) and extremely highly domed, with numerous narrow coils that often have a characteristic sculpture.
The facts about their taxonomy are rather sparse, which is made difficult by the high diversity and variability of the species. Most triphorid collections in natural history museums are still undescribed.
The type locality for the description of Viriola intergranosa is the Loyalty Islands, another description comes from New Caledonia. The last whorl on the shell is flattened. The siphon is short, partially closed, obliquely curved and yellowish. Arched columella, brownish. The columella lip is round and protruding and connected to the beginning of the siphon.
