Diagnosis
ReferenceDiagnosis
A. W. Hunter et al. 2007Interradial outline of the disc straight or concave (but may be convex). Oral and aboral faces of the disc with small scales of uncertain outline covered with granulated integument. Oral face
covered with spines. Probably no true marginalia present. Disc margins often thickened on aboral faces(possible post-mortem folding of the skin after death). Mouth angle plates short, with oral side covered with large papillae. Ambulacrals with typical boot-shaped ridge on the oral side of arms. Median suture between alternate ambulacrals straight, with sinuous appearance between neighbouring boot-shaped ridges. Excavations for the dorsal longitudinal muscles not very broad. Aboral outline of ambulacrals trapezoidal to quadrate. Laterals ear-shaped, with vertical and groove spines.
