Type genus

Ophiocamax Lyman, 1878a (type species: O. vitrea Lyman, 1878a ).

Diagnosis

Dorsal disc with spines with multipointed crowns. Ventral cluster of spiniform teeth, dental plate entire, sockets small, not penetrating. Numerous spiniform oral papillae clustered at lateral jaw edges. Vertebral articulation hourglass-shaped.Arm spines thin, round in cross section, with lateral thorns. Pointed thornlike tubercles on dorsal, ventral and lateral arm plates. Proximal tentacle pores with multiple elongated erect scales, forming a sheath through which the foot emerges, distally a single thorny scale, penetrated by foot ( O. vitrea ). Arm spine articulations conspicuously large muscle opening encompassed by rather thin dorsal and ventral lobes forming an irregular circle. Row of spine articulations on midline of raised distal portion of lateral arm plate. Second or third dorsalmost spine articulation often much larger than others.
