1991: 57, pl. 60, fig. 1.

Test variable in size, usually medium, a medium-height trochospire with 4–6 subspherical to radially slightly flattened chambers in the final whorl. Chambers increase slowly in size as added, sutures depressed.Aperture a wide and deep opening directly into umbilicus. Remarks:A few individuals with a lower trochospire and more umbilical aperture were found ( Figs 4F, 4I View Fig ) in our material. These forms may be identified as N. eggeri ( Rhumbler, 1901) . Saito et al. (1981) separate these species on the basis of a higher spire in N. dutertrei , but Kennett and Srinivasan (1983) suppose that N. eggeri is a junior synonym of N. dutertrei . We tend to agree with the latter opinion at this stage.

N. dutertrei differs from N. incompta in having a bigger and less compact test, and in having more chambers in the final whorl.

Distribution: Equatorial and tropical waters. A common species in our material.
