Stenodrillia Horrenda
''Stenodrillia horrenda'' is a species of sea snail, a marine gastropod mollusk in the family Drilliidae.Rosenberg, G. (2015). Stenodrillia horrenda. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=420319 on 2016-12-12 Description The length of the shell attains 60 mm. (Original description) The very coarse and strong, long, narrow shell has with a concave conical base. It shows huge hunchy ribs, and coarse spiral threads. Its longitudinal sculpture is characterized by six enormous bunchy oblique ribs on each whorl, which die out on the base and at the sinus below the suture, but reach the suture at the bottom of the upper whorls. They are parted by broad open furrows, which run obliquely to the left and more or less continuously down the spire. These ribs and furrows are roughened by coarse unequal lines of growth. The surface is scored by strong rough spiral threads parted by wider furr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drilliidae
The Drilliidae are a Taxonomy (biology), taxonomic family (biology), family of small predatory sea snails with high-spired shells. They are classified as marine (ocean), marine gastropod mollusks in the superfamily Conoidea. This family has no subfamilies. It consists of about 30 genera and approximately 500 Recent species. Description The shell is claviform with a tall spire, or squatly conical to biconical. In many species, the siphonal canal is truncated. The aperture (mollusc), aperture is U-shaped with a parietal callus pad. The sculpture of the shell shows prominent axial ribs with a polished surface. Most species have a dorsal varix (mollusc), varix (transverse elevation), except in the genera ''Cymatosyrinx'', ''Elaeocyma'' and ''Splendrillia''. The protoconch can be smooth or very carinate. The ovate operculum (gastropod), operculum has a terminal nucleus. The radula of the species in this family have characteristically five teeth in each row (formula : 1 + 1 + 1 + 1 + ...

Compsodrillia Acestra
''Compsodrillia acestra'' is a species of sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, the turrids and allies. Description The length of the shell attains 19 mm, its diameter 5.5 mm. (Original description) The shell is long and slender. It has a pale olive-color with a translucent white tip. It contains 9 whorls, with a smooth vitreous rounded two-whorled protoconch. The fasciole is wide, steep, excavated and marked with close-set fine even spirals.;It is bounded behind by a sharply cut elevated thread, a little space in front of the suture. The whorl in front of the fasciole is covered with close-set, strong, subequal, flattish spirals, with narrow channelled interspaces. These spirals, from two on the four apical whorls, increase to seven on the penultimate whorl, and eleven (behind those on the siphonal canal) on the b ody whorl. Here they are a little more widely separated, and have one or two intercalary fine threads in the interspaces ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compsodrillia Eucosmia
''Compsodrillia eucosmia'' is a species of sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, the turrids and allies. Description The length of the shell varies between 10 mm and 25 mm. (Original description) The color of the shell is pale, with touches of pale brown and a peripheral whitish zone. It contains 8 whorls, with a glossy, rounded protoconch of two whorls. The fasciole is rather wide, excavated, undulating in harmony with the ribs, marked by fine revolving threads and marginated at the appressed suture by a stout elevated line. The spiral sculpture on the rest of the shell (1) consists of (on the whorls preceding the body whorl) two or three prominent white stout threads, somewhat swollen where they ride over the ribs. On the body whorl there are about fifteen of these primary spirals. Between the fasciole and the end of the siphonal canal, in each of the wide interspaces, are (2) three or four much finer hardly elevated flattish threa ...

Compsodrillia Gundlachi
''Compsodrillia gundlachi'' is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies. The specific epithet is named after Cuban naturalist Juan Gundlach. Description The length of the shell attains 50 mm. The original description is as follows: "The solid, slender shell is pale brown or whitish. It contains ten whorls (the nepionic whorls lost) strongly appressed at the suture; anal fascicle close to the suture,. The whorls are smooth or faintly spirally striated, rather wide and excavated. The notch is wide, not very deep. The sculpture consists of about six strong, short, turgid ribs obsolete in front of the periphery and on the last half of the body whorl. These are crossed by from two to five spiral threads stronger on the summits of the ribs, especially the pair which first appear, and faint, finer, spiral striations between the ribs. The lines of growth are well marked. The aperture is elongate. The outer lip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compsodrillia Haliostrephis
''Compsodrillia haliostrephis'' , common name the spindle drillia, is a species of sea snail, a marine gastropod mollusc in the family (biology), family Pseudomelatomidae, the turrids and allies. Description The length of the shell varies between 10 mm and 25 mm. (Original description) The pure white shell of the holotype contains 8 Whorl (mollusc), whorls with a glossy rounded vitreous protoconch of two whorls. The spiral sculpture resembles much as in ''Compsodrillia eucosmia'', a line marginating the suture. There are two or three strong primaries on the upper whorls, five or six on the body whorl, and eight or ten smaller ones on the siphonal canal. The principal primaries are strongly marked and slightly swollen on the summits of the ribs. The secondary spirals, very faint or absent behind the periphery but present in the interspaces in front of it, are finer than in the ''C. eucosmia'', and more numerous. The fasciole is wide, nearly smooth, undulated, and little ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
