Extra details from original publication
Remarks - Although the final chamber is similar to that of the spinose Turborotalita quinqueloba (Natland), Tenuitella jamesi is distinguished by its microperforate and pustulate wall. A form described as Globorotalia sp. 4 by Jenkins and Orr (1972, pl. 18, figs. 7-12) and as Tenuitella sp. by Fleisher (1974, p. 1134) and Li (1987, p. 311), differs from T. jamesi in the huge lip, but both have a similar range in the Miocene.

Distribution - Tenuitella jamesi ranged from the lower middle Miocene to the middle middle Miocene in Hole 747A.
