General description

Tests in Androsina are planispirally coiled and involute in early stages, later chambers become peneropliform, then flabelliform and finally broadly arched but not annular. The interior of chambers is divided by pillars. Living specimens appear brownish - greenish and harbour chlorophycean endosymbionts.

General description

Test growth in Cyclorbiculina compressa starts with planispiral and involute chambers that rapidly increase in size and finally become annular.Chambers are divided by partitions. Living specimens possess a green colour due to chlorophycean endosymbionts.

General description

Laevipeneroplis bradyi have planispiral tests with chambers that are partially evolute in early stages and later become flaring. Living specimens show a bright green colour due to chlorophycean endosymbionts.

General description

Early chambers are planispiral and involute, later ones are more or less flaring. Hallock and Peebles (1993) state that this species is morphologically very variable. Chlorophyte symbionts lead to a green colour in living specimens.

Description Bock, W., D., Lynts, G., W., Smith, S., Wright, R., Hay, W., W., Jones, J., I., 1971, Miami Geological Society Publications, Memoir 1

General description

Peneroplid coiling of early chambers. The later portion of the test becomes uncoiled and uniserial. Living specimens are red due to rhodophycean symbionts.
