Original Description

Abundant in Bortonian and reaching Whangai below and Kaiata just above is a true Globigerina of the bulloides-triloba type, which is easily distinguished from the more typical forms in later horizons by a slight flattening and compression of each chamber and especially by its wide but very low and hardly open aperture directed laterally to overhang a previous chamber, instead of centrally, and with a pronounced rim. This may be called Globigerina. linaperta. n.sp. (plate 13, figs. 54-57) [Finlay 1939 No. 2]
