Diagnosis
ReferenceDiagnosis
T. W. Amsden 1974This genus comprises virgianids with small, smooth shells having a ventral sulcus and a dorsal fold. The dorsal apparatus consists of noncarinate, narrow, flattened processes overlain by inner plates and supported on very short, discrete outer plates (text-fig. 37). The ventral interior has a small spondylium supported on a short septum.
