Basilissopsis

	Basilissopsis ''Basilissopsis'' is a genus of sea snails in the family Seguenziidae. In 1897 Dautzenberg and Fischer created this new genus for their specimen of ''Basilissopsis watsoni'', based on the shell characteristics of discolored specimens that were non-nacreous and lacked labral sinuses. This was however contradicted later by the discovery of other species in this genus that possess nacre and labral sinuses. This puts this genus in the family Seguenziidae. Description Nothing is known of the anatomy of the soft body in these species. The conical shell has peripheral carina and collabral axial riblets. All whorls contain midwhorl angulation but spiral lirae are absent. The U-shaped posterior sinus is shallow. There is no anterolateral sinus. A basal sinus is present. A columellar sinus is lacking. The aperture has a rhomboidal shape. A columellar tooth is lacking. The umbilicus contains a septum. The shell has no microsculpture. There are no data about the radula. Species Species ...

These ribs in crossing the upper carina form small sharp-pointed tubercles, of which there is also a trace on the lower carina. The superior sinus lies just above the upper carina, the basal sinus toward the middle of the base. Both are well marked. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	William Healey Dall William Healey Dall (August 21, 1845 – March 27, 1927) was an American naturalist, a prominent malacologist, and one of the earliest scientific explorers of interior Alaska. He described many mollusks of the Pacific Northwest of America, and was for many years America's preeminent authority on living and fossil mollusks. Dall also made substantial contributions to ornithology, zoology, physical and cultural anthropology, oceanography and paleontology. In addition he carried out meteorological observations in Alaska for the Smithsonian Institution. Biography Early life Dall was born in Boston, Massachusetts. His father Charles Henry Appleton Dall, (1816–86), a Unitarian minister, moved in 1855 to India as a missionary. His family however stayed in Massachusetts, where Dall's mother Caroline Wells Healey was a teacher, transcendentalist, reformer, and pioneer feminist. In 1862, Dall's father, on one of his few brief visits home, brought his son in contact with some na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
