Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. H. C. Hotchkiss 1993 | Carinal spines begin their series at or near the center of the disc and number approximately 13 in the space of eight ambulacrals. The carinal spines are preserved in a rigid erect position and are probably fused to the upper arm plates. Similar plates and spines occupy the rest of the aboral surface of the disc, diminish in size toward the interradial margins, and are smaller still on the oral interradii. Splayed uppermost vertical spines are very short, less than half the length of an arm segment and do not materially contribute to the overall width of the arm. Interradial outline of disc tends to be concave. |
