''Hindsiclava perspirata'' is an extinct species of sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, the turrids and allies. Description The length of the shell attains 29 mm, its diameter 10 mm.

Hindsiclava Polytorta
''Hindsiclava polytorta'' is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae. Description The length of the shell varies between 30 mm and 60 mm. (Original description) The large, slender, solid, shell contains about thirteen whorls. These are of a dull ashen color and unpolished surface. The protoconch is missing. The succeeding whorls are transversely sculptured by twelve or thirteen rounded, shouldered ribs. These begin and are largest just before the notch-band, crossing the whorls a little obliquely or even in a directly transverse direction. They become widest at the beginning, becoming narrower and less prominent anteriorly. They fade out or become indistinct on the body whorl on the anterior half, and are less numerous or partially obliterated over the latter part of this whorl in fully developed adults. The lines of growth are more or less distinct, but not uniform, while the ribs on one whorl bear no uniform relation in p ...
