|---|---|---|
| F. H. C. Hotchkiss 1993 | Carinal spines (inferred from sockets) begin their series midway between center and edge of disc, extend onto the arms, and number about five in the space of four ambulacrals. The carinal spines are not erect, and are not fused to the upper arm plates. The splay of the uppermost vertical spines nearly doubles the overall arm width so that it nearly equals the disc radius. Aboral surface of disc ornamented with granules and with few scattered spines (presence inferred from
sockets). Oral interradii with numerous spines. |
