| As shown by Fryda and Blodgett, the shell characters of Alaskacirrus fit well with the diagnosis of the family Cirridae Cossmann, 1916, as emended by Bandel. |
| It is clear, however, that Mamet and Pinard's diagnosis of the protonodosariid wall as a microgranular tectum must be emended. |
| A new genus, Ristedtoceras, is erected and the genus Pseudorthoceras Girty, 1911 is emended. |
| In 1969, Rolfe correctly emended the spellings of the archaeostracan families by inserting id before the familial suffix. |
| Among all the functions related to the septal marginal fluting, the one suggested by Spath is emended and elaborated herein as the most reasonable one. |
| The genus is emended to account for the nature of the central body wall, as well as new evidence of tabulation including details of the archeopyle. |
