| It may be desirable to separate generically the species having the hemispherical apertures, median ciliated pore, and sublateral avicularium. |
| The supplied inserts include apertures, posts of various widths, and cross hairs. |
| The polypides of living stenolaemates grow inwardly from skeletal apertures. |
| Together, this indicates that the length is about twice as long as the width and the apertures appear more slit-like than round holes. |
| To estimate the relative surface area of basal lamina and apertures, we used a line intercept technique with cycloids. |
| Consisting of a grid of iris diaphragms, the facade's surface has changing apertures. |
