"This Sumatran form appears to be a new species. It is typified by being somewhat biconvex with subrounded, lobulated periphery; chambers slightly oblique and increasing only slightly in size as added with exception of last chamber which is usually the largest, five to six in last-formed whorl; sutures ventrally depressed, slightly curved to straight and more or less radial, dorsally rather strongly curved, slightly depressed; wall smooth, finely perforate; aperture opens ventrally and is covered by a distinct lip. Diameter 0.40 mm.; thickness 0.15 mm. "This form is frequently found in the late Tertiary deposits of the East Indian Region. In Sumatra it is common in the Transitional Zone and is sometimes associated with Globorotalia aff. canariensis (d'Orbignyl. "This species appears related to Globorotalia quadraria Cushman described from the Miocene of Louisiana which differs from the Sumatran form by the chambers increasing in size more rapidly as added."

The synonymy of G. barisanensis with G. fohsi is contested: "G. barisanensis appears to be a valid name and a senior synonym of G. peripheroacuta. However, we recommend that it will be more practical to conserve the latter name, which is well established in the literature."

thanks for pointing that out, I've added a note on this - and it will need to addressed by the Neogene working group. Jeremy
