NEW SPECIES AND A NEW GENUS OF NEOGENE BENTHIC FORAMINIFERA FROM THE SOUTHWEST PACIFIC-OCEAN

Nine new species of benthic foraminifera are described from sediments of the southwest Pacific Ocean. All are bathyal to abyssal in their di stribution. Two of them, Globocassidulina hooperi n. sp. and Pseudopar rella parca n. sp., are particularly significant because their occurre nce is limited to abyssal depths, coincident with the distribution of Antarctic Bottom Water and its close derivatives. A distinct mode of c hamber arrangement, combining two styles of biserial development, char acterizes Hooperella strigata, n. gen., n. sp., which serves as the ba sis for the erection of Hooperellidae, a new family in the superfamily Cassidulinacea. The other species to be described herein are Ammobacu lites paradoxus, Globulotuba scrippsi, Turrilina hadra, Schackoinella favoculcita, Heronallenia cursa, and Nonion belfordi. Lectotype and pa ralectotype specimens are designated for Ammobaculites filiformis Earl and.
