Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. H. Flower 1962 | Orthocerids with smooth or annulated, orthoconic or slightly cyrtoconic conchs with straight sutures. Relatively close septal spacing of ellesmeroceridan aspect (five or more chambers over a distance comparable to conch cross section diameter). Siphuncle is central or located between conch wall and center, but never marginal. Siphuncle is narrow, tubular, or slightly expanded between the septa. Connecting rings are relatively thicker than in other Orthocerida. Septal necks are suborthochoanitic or orthochoanitic. Endosiphuncular deposits occur in apical parts of nearly mature specimens, and either form an irregular lining or are composed of endosiphuncular rods. Cameral deposits are mural and episeptal in apical portions the conch |
