Pinguigemmula
''Cryptogemma'' is a genus of sea snails, marine gastropod mollusks in the family Turridae, the turrids. Distribution These are deep-sea species with a wide geographic distribution. Species According to Zaccharias ''et al.'' (2020) this genus should only include: * '' Cryptogemma aethiopica'' (Thiele, 1925) * '' Cryptogemma periscelida'' (Dall, 1889) * '' Cryptogemma phymatias'' (Watson, 1886) * '' Cryptogemma powelli'' Zaharias, Kantor, Fedosov, Criscione, Hallan, Kano, Bardin & Puillandre, 2020 * '' Cryptogemma praesignis'' (Smith, 1895) * '' Cryptogemma tessellata'' (Powell, 1964) * '' Cryptogemma timorensis'' (Tesch, 1915) * ''Cryptogemma unilineata'' (Powell, 1964). The others should be excluded from this genus because the lack key characters such as the narrow fusiform shell and the well-marked peripheral anal sinus. They show closer resemblances to other conoidean families (such as Horaiclavidae) than to Turridae. Species within the genus ''Cryptogemma'' include (acco ...

Turridae
Turridae is a taxonomic family name for a number of predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. MolluscaBase (2018). Turridae H. Adams & A. Adams, 1853 (1838). Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=152 on 2018-07-22 The family name Turridae was originally given to a very large group of several thousand sea snail species that were thought to be closely related. The family was described with about 700 genus-group taxa and an estimated 10,000 recent and fossil species. However, that original grouping was discovered to be polyphyletic. In recent years, the family Turridae has been much reduced in size, because a number of other families were created to contain the monophyletic lineages that had previously been thought to belong in the same family. The common name ''turrids'' is still used informally to refer to the polyphyletic group. Distribution Species in the family ...

Carinoturris Polycaste
''Carinoturris polycaste'' is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies. Description The length of the shell attains 14 mm, its diameter 5.5 mm. (Original description) The white shell has a pale olivaceous periostracum. It contains five whorls exclusive of the (lost) protoconch. These are rather slender and moderately rounded except for a single strong peripheral keel which marks the deepest part of the anal sulcus. The suture is distinct, not appressed, with a feebly indicated flattish area between it and the posterior edge of the anal fasciole, which between the keel and the flattening is slightly impressed. There is no other spiral sculpture and the axial sculpture consists mostly of moderately prominent incremental lines. The anal sulcus is deep and wide. The outer lip is thin, prominently arcuately produced. The inner lip is smooth. The columella is very short and gyrate. The axis is pervious. The si ...

Borsonella Callicesta
''Borsonella callicesta'' is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae. Description The small shell is white, covered with an olivaceous periostracum, and with four whorls exclusive of an apical whorl or two (which in the specimens is always eroded). The suture is distinct. The edge of the whorl in front of it is slightly thickened. The spiral sculpture on the upper whorls consists of a somewhat blunt peripheral keel, undulated more or less toward the apex and obsolete on the body whorl. Other sculpture consists of minute, broken, irregular, more or less oblique, usually punctate impressed lines. The aperture is simple. The outer lip is sharp. The body of the shell is erased and white. The siphonal canal is short, somewhat recurved The height of four whorls, 15 mm; of the body whorl, 10 mm; diameter of the shell: 7 mm.

Carinoturris Adrastia
''Carinoturris adrastia'' is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies. Description The length of the decollate holotype attains 16 cm, its diameter 6.25 mm. (Original description) The white shell has a thin, pale olive periostracum. The apex is invariably eroded, and the subsequent whorls, eight or more, are polished and faintly showing incremental lines. The suture is inconspicuous, the anterior margin is sometimes raised like a small cord. The spiral sculpture consists of a strong, sometimes nodulous or undulated peripheral keel, rather nearer the succeeding suture than to the preceding one, the latter space occupied by the slightly concave anal fasciole. The axial sculpture consists only of arcuate incremental lines. The base of the shell is rounded;. The aperture is narrow. The outer lip is thin, sharp, produced and internally smooth. The anal sulcus is wide and shallow, with no parietal nodule. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptogemma Quentinensis
''Cryptogemma quentinensis'' is a species of sea snail in the family Turridae. Description The length of the shell attains 12 mm, its diameter 5 mm. (Original description) The small, solid shell is white under an olivaceous periostracum. It has five (decollate) whorls. The suture is distinct, bordered by a rounded ridge on each side. The surface is dull. The spiral sculpture consists of a prominent nodulous peripheral ridge which is the anal fasciole, with two smaller ridges in front of it with wider interspaces. In front of the first of these the suture is laid. The space between this and the second is more or less channeled, but these two ridges are not nodulous. In front of these four or five obscure threads appear on the siphonal canal The siphonal canal is an anatomical feature of the shells of certain groups of sea snails within the clade Neogastropoda.

Cryptogemma Polystephanus
''Cryptogemma polystephanus'' is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids. Description The length of the shell attains 25 mm. (Original description) The shell of moderate size contains six or more whorls. The protoconch is eroded. The shell is white, with a cream-colored periostracum. The spiral sculpture consists numerous fine, subequal, flattisb threads with narrower interspaces, which cover the whole shell. To these are added a thickened ridge which borders the anterior margin of the suture, and on the spire a peripheral nodose keel, which is less marked on the body whorl, where it forms the shoulder.oO the penultimate whorl there are twenty of these nodules. Other axial sculpture is furnished by line, short, sharp elevated wrinkles which cross retractively the ridge adjacent to the suture, like the "gathers" of a skirt, and become obsolete on the fasciole. There are twenty-eight of these wrinkles on the margin of the penultimate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cryptogemma Oregonensis
''Cryptogemma oregonensis'' is a species of sea snail, a marine gastropod mollusk in the family Turridae, the turrids. Description The small, white shell has a pale olivaceous periostracum. It consists of more than four whorls but the apex is eroded. The suture is distinct. The whorl in front of the suture as far as the shoulder is flattish. The shoulder of the whorl is strongly marked and angular. It is coronated on the penultimate whorl by the ends of about 25 straight, protractively oblique narrow ribs with subequal interspaces, becoming obsolete on the base of the body whorl.
