Hemilienardia

Hemilienardia is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae, the turrids.
Description
This genus is readily distinguishable from Lienardia by the apex. The multispiral protoconch consists of a cone of 3½ smooth rounded whorls. It lacks the characteristic diagonally cancellated sculpture of the other genera in this family. The succeeding adult whorls not only differ in sculpture, but are wound in so divergent a spiral and increase at so disproportionate rate as to project that protoconch in a mucronate point. In the colour of the type the contrast is even more violent, as there the brilliant snow-white apex against the deep rose-red is visible to the naked eye. Another generic feature is an opaque peripheral zone. The deep-seated columella folds, so conspicuous in Lienardia, are here less developed. The species are small, short, stumpy and usually brightly coloured. They frequent the upper zone of coral reefs.
