Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| H. B. Brady 1881 | With Reuss's genera Chilostomella and Allomorphina, which together from his family Cryptostegia, I have associated Seguenza's genus Ellipsoidina. The anomalous characters of the latter, viewed as a Nodosarian, I pointed out many years ago, and had I then known the genus Chilostomella by anything more than figures, I should have suggested the present position for it. The primary difference in the structure of these two types consists in the fact that in Chilostomella the segments alternate, the attachment to each other being at one side, and the aperture first at one end and then at the other, whilst in Ellipsoidina the attachment is at the base, the segments grow in the same direction, and consequently the aperture is always at the same end. |
