Diagnosis
ReferenceDiagnosis
H. Matsumoto 1915Disk and arms covered by a thick skin. Radial shields very rudimentary and insignificant. Single oral papilla on either side and two or three dental papilla at the apex of each jaw. Teeth in a single vertical series. Teeth and papillae all alike, stout, stumpy, conspicuously thorny at tips. Second oral tentacle pores open outside oral slits, each provided with a thorny, stumpy papilla, which arises from adoral shield. Dorsal arm plates absent, while the lateral arm plates are subventral, so that the dorsal side of the arms is merely covered by a naked skin. Ventral arm plates welldeveloped, in contact with each other. Vertebrae short and very stout. Vertebral articulation streptospondyline, the articular peg being entirely ibsent. Arm spines few, converted into compound hooks. No tentacle scale.
