Basilissopsis Charcoti
''Basilissopsis'' is a genus of sea snails in the family (biology), family Seguenziidae. In 1897 Philippe Dautzenberg, Dautzenberg and Paul Henri Fischer, 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 Whorl (mollusc), whorls contain midwhorl angulation but spiral Lira (mollusc), lirae are absent. The U-shaped posterior sinus is shallow. There is no anterolateral sinus.

Philippe Dautzenberg
Philippe Dautzenberg (20 December 1849, in Ixelles, Brussels – 9 May 1935, in Paris) was a Belgian malacologist, a biologist who specializes in the branch of invertebrate zoology that deals with mollusks. He was an amateur and autodidacticism, autodidact, who was actually the owner of a carpet and soft furnishings factory. He was also a devoted family man with 12 children. He assembled, thanks to his many connections all over the world, a large part of the shell collecting, shell collection of the Royal Belgian Institute of Natural Sciences, which consists of 9,000,000 specimens and is one of the three largest shell collections in the world. He was a participant in the scientific surveys of Prince Albert I of Monaco and the author of 210 published works (between 1881 and 1937 (post mortem) ) in the field of malacology. He described 1895 new taxa. He collected shells from an early age, resulting in his personal collection of about 4.5 million specimens, relating to 33,000 Rece ...
