<p><strong>Abstract.</strong> A review of the taxonomic history of the agglutinated (benthonic) foraminiferal genus <i>Cribrostomoides</i> Cushman, 1910 reveals much confusion concerning its type species, coiling mode and apertural characteristics. We believe the originally designated type species of <i>Cribrostomoides</i> Cushman, 1910, <i>C. bradyi</i> Cushman, 1910, to be no more than varietally (i.e. infra-subspecifically) distinct from, and therefore a junior synonym of, <i>Haplophragmoides subglobosus</i> Cushman, 1910. The coiling of <i>Cribrostomoides</i>, as typified by <i>C. subglobosus</i> (Cushman, 1910), is in the form of an involute streptospire characterised by a repeated alternation in axis. The aperture of the genus is equatorially or asymmetrically placed and interio-areal and single (in megalospheric and juvenile microspheric specimens) to areal and multiple (in microspheric adults). In order to stabilise the concept of <i>Cribrostomoides,</i> we have designated lectotypes for both <i>C. bradyi</i> and <i>H. subglobosus,</i> and have also emended the generic diagnosis of Loeblich and Tappan (1987). Criteria for the discrimination of <i>Cribrostomoides</i> emend, herein and allied genera are tabulated.</p>
