holotype: V. carseyae
holotype: V. carseyae
topotype: V. carseyae
topotype: V. carseyae
x: V. carseyaeOriginal description: Test V-shaped, laterally somewhat compressed, composed throughout much of its development of appressed, well-in flated, distinctly striate biserial chambers that increase rapidly in size with growth, later chambers arranged ir regularly in the plane of biseriality forming a fully mature test that is somewhat fan-shaped in peripheral outline; sutures deeply incised; aperture a broad lunate opening at base of septal face of biserial portion of test and a similar opening on each side of many of the later chambers.
Entries in the Catalog of original descriptions: Ventilabrella carseyae
Emended description: Biserial chambers deeper than wide followed by one or two sets of multiserial chamberlets. Test V-shaped, laterally somewhat compressed, composed throughout much of its development of appressed, well-inflated, distinctly striate biserial chambers that increase rapidly in size with growth, later chambers arranged irregularly in the plane of biseriality forming a fully mature test that is somewhat fan-shaped in peripheral outline; sutures deeply incised; aperture a broad lunate opening at base of septal face of biserial portion of test and a similar opening on each side of many of the later chambers.
