Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. Matsumoto 1915 | Ophiuroidea without external ambulacral grooves, and with ventral arm plates. Radial shields, genital plates and scales, oral shields and dorsal arm plates usually present; but sometimes rudimentary or absent. Ambulacral plates opposite, usually completely soldered in pairs to form the vertebrz. Madreporite represented by one, or sometimes all, of the oral shields. |
