Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. Skawina and J. Dzik 2011 | ‘The shell is thick and varies in shape from broadly oval to narrow sub-quadrate. Anteriorly, the shell is broadly, and posteriorly somewhat narrowly rounded or sub-angular. The length is in all cases greater than the height, relative proportions varying within wide limits. The beaks are anteriorly situated but are not terminal; they are inconspicuous and curved inwards and very slightly.' |
