Ophioderma Müller and Troschel, 1842


Ophioderma Müller and Troschel, 1842 

Type species. Asterias longicauda Retzius, 1805  , by subsequent designation, Clark, 1915.

Although the most conspicuous characteristic of the genus, i.e. the genital slits, are not visible, the presence of large disks with very small scales covered by granules, firmy fused subrounded arms, very short, flat, and addpressed arm spines, and two flat genital scales, lead us to include the fossils in Ophioderma  .
