Fusiturricula
''Fusiturricula'' is a genus of sea snails, marine gastropod mollusks in the family Drilliidae. Taxonomy The genus ''Fusiturricula'' (together with '' Cruziturricula'') forms an unsupported group that is sister clade to Drilliidae in the cladogram of the molecular phylogeny of the Conoidea.. The type species of ''Fusiturricula'', ''Turris fusinella'' Dall, 1908, is even different from what is currently conceived as belonging to that genus, but those species are similar to ''Cruziturricula'' ''sensu auctt.'' Although ''Fusiturricula'' (and ''Cruziturricula'') definitely do not belong in the family Drilliidae (they may represent a new family), they are assigned in the Drilliidae provisionally as a working hypothesis. This genus is included in the family ''Cochlespiridae Cochlespiridae is a Taxonomy (biology), taxonomic family (biology), family of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. This family is not well differentiated morphologically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fusiturricula Armilda
''Fusiturricula armilda'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The size of an adult shell varies between 17 mm and 60 mm. (Original description) The small, delicate shell is fleshy white, obscurely banded with brown, a pale belt on the body whorl just in front of the periphery. It contains 8 whorls excluding the (lost) protoconch. The spire is acute, slightly shorter than the aperture including the siphonal canal. The whorls show a conspicuous shoulder, above which a slightly concave spirally striate anal fasciole extends to the appressed suture, which on the last whorl or two shows indications of a marginal thickening. The axial sculpture consists of (on the body whorl, about fifteen) protractive short riblets with subequal or slightly shorter interspaces apparently confined to the periphery: these are crossed by t\ro strong spiral threads, the posterior largest and forming oblong tumid nodules at the intersection ...

Fusiturricula Bajanensis
''Fusiturricula bajanensis'' is a species of sea snails, a marine gastropod mollusc in the family Drilliidae. It is also considered a synonym of '' Fusiturricula jaquensis'' (G.B. II Sowerby, 1850), but according to Fossilworks it is a synonym of † '' Fusiturricula springvaleensis'' Mansfield 1925 Description The size of an adult shell varies between 35 mm and 85 mm. Distribution This species occurs in the demersal zone of the Caribbean Sea off St. Croix and Barbados Barbados is an island country in the Lesser Antilles of the West Indies, in the Caribbean region of the Americas, and the most easterly of the Caribbean Islands. It occupies an area of and has a population of about 287,000 (2019 estimate). .... References * Tucker, J.K. 2004 ''Catalog of recent and fossil turrids (Mollusca: Gastropoda).''

Fusiturricula Fenimorei
''Fusiturricula fenimorei'', common name Fenimore's turrid, is a species of sea snail, a marine gastropod mollusk in the family Drilliidae. Description The size of an adult shell varies between 30 mm and 71 mm. (Original description) The very large shell has a fusus-like shape. It is milk-white, covered with a very thin translucent periostracum. The whorls of the protoconch are decollated. The postnuclear whorls are strongly rounded. They are marked by almost knoblike axial ribs, which extend from the anterior limit of the posterior sinus to the periphery. These ribs are almost as wide as the spaces that separate them. In addition to this the whorls are marked by sigmoid axial lines of growth. Of these ribs, 10 occur upon all but the penultimate and the body whorl, each of which has 12. The spiral sculpture consists of fine threads, which in the sinus portion near the summit of the early turns are about as strong as the spiral threads anterior to this, but on the later ...
