Aforia Circinata
''Aforia circinata'', common name the ridged turrid, is a species of sea snail, a marine gastropod mollusk in the family Cochlespiridae. Description The shell grows to a length of 75 mm. The slender, elongated shell is coated with a brownish epidermis. It features six evenly rounded whorls, characterized by a sharp carina. Above the carina, the shell is smooth, while below it, the surface is grooved with wider interspaces. The deep anal sinus is situated approximately one-third of the way from the carina to the suture.

Aforia Goniodes
''Aforia goniodes'' is a species of sea snail, a marine gastropod mollusk in the family Cochlespiridae. Description The shell size varies between 40 mm and 85 mm (Original description) The high, narrow shell exhibits a biconical shape, with a subscalar profile.

Below the periphery, the spiral sculpture features narrow, shallow grooves that separate wider, almost obsolete threads. At the periphery, there is an obtuse carina that is sharper on the early whorls. Behind this carina is a wide, shallow sulcus, followed by the whorl rounding towards the distinct but unchannelled suture. The upper or posterior part of the whorl shows fine spirals that are perceptible but fainter than those in front of the periphery. The transvers ...

Aforia Crebristriata
''Aforia crebristriata'' is a species of sea snail, a marine gastropod mollusk in the family Cochlespiridae. It is also considered as the type species of the genus '' Dallaforia'' through its synonym ''Irenosyrinx crebristriata'' Dall, 1908 Description The length of the shell attains 48 mm, its diameter 16.5 mm.
