The outer surface is sharply, spirally striate and closely obliquely striated . The shell has a more or less developed callous ridge or funicle revolving on the inner side of the whorl within the umbilicus, and terminating at the columella, the edge of which is reflexed over it. The sinuous columella terminates in a point or denticle at its base. The outer lip is lirate within. Distribution The habitat of most species is in the Indian Ocean, but some occur in the Pacific Ocean. Species Species within the genus ''Monilea'' include: * '' Monilea belcheri'' (Philippi, 1849) * ''Monilea callifera'' (Lamarck, 1822), the type species * '' Monilea carmesina'' (Webster G.H., 1908) * '' Monilea chiliarches'' Melvill, 1910 * '' Monilea cocoa'' Okutani, 2001 * '' Monilea discerna'' (Iredale, 1937): (synonym: ''Talopena discerna'' Iredale, 1937) * ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
