This name is considered a
nomen dubium.[1] Hedley (1922: 260) and Powell (1966: 109) summarized the arguments against using the earlier name Cythara Schumacher, 1817, with much uncertainty regarding the identity of its type species, against Eucythara Fischer, 1883. The name has also been used by European authors (e.g. Knudsen, 1952; Nordsieck, 1977) for species classified now in MangeliaRisso, 1826.[1]
Description
The tropical shell is relatively large. It is columbelliform and longitudinally costellated. The
spire is short. The
aperture is narrow and elongated. The outer
lip is denticulated within. The columellar lip is striated.[2]
The margin of the mantle is slightly dilated on the right side.
The shell is fusiform, smooth and longitudinally plicated or rihbed. The
aperture is linear, posteriorly subemarginate. The
siphonal canal is very short and nearly straight. The
columella is subflexuous and transversely striated. The inner
lip is posteriorly callous. The outer lip is margined, denticulate, or striated internally.[3]
