Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| C. W. Merriam 1974 | This Siphonophrentis has a ceratoid to cylindrical growth habit that reflects frequent rejuvenescence and elongate curved corallites. Septa are withdrawn from axis; minor septa are very short (or unrecognizable). Tabulae are complete, occasionally straight, but more commonly uparched distally and either flat medially or with a slight sag. Tabulae are usually rather widely spaced. The wall has a very nar- row stereozone for this genus. There are no dissepments, but there are occasional looplike or globose tabellae. The abrupt curvature changes on rejuvenes- cence all caused by the resumption of upright growth |
