Chelonechinus javanensis Bather 1934, p. 834
| Diagnostic Features | Imperfect specimen, shape suggests a higher dome than those of C. crassus and C. suvae. Ambulacral pores, when seen, are central, minute, and single. Slightly convex plates. [Bather 1934] |
|---|---|
| Distribution | Tertiary of Gemborg, Java. |
| Type | Natural History Museum plaster cast of holotype E75751 |
| Classification and/or Status | Species of Chelonechinus |
| Remarks | Differs from C suavae and C crassus in having plates that are thinner and more convex, and a more marked ridging of the interambulacrals, which strengthens them and allows for a higher dome.
